Frequency  
Th e Nº390S CD Processor is set at th e factory (in tern ally) for 100V,  
120V, 200V, 220V, or 240V AC m ain s operation as appropriate for  
th e coun try in wh ich it is to be sold. Make sure th at th e label on  
th e rear of th e Nº390S (adjacen t to th e power cord) in dicates th e  
correct AC operatin g voltage for your location , as attem ptin g to  
operate th e Nº390S at an in correct voltage can dam age th e un it.  
Th e Nº390S CD Processor is also set at th e factory for operation  
on eith er 50 or 60 Hz AC lin e frequen cies, as appropriate for th e  
coun try in wh ich it is to be sold. It will n ot operate if it sen ses an  
in correct lin e frequen cy.  
9
Warning!  
Neither the voltage nor the line frequency setting may be  
changed by the user. There are no user serviceable parts inside  
the Nº390S. Only qualified, authorized service personnel may  
open the Nº390S CD Processor, as hazardous voltages exist  
w ithin the unit.  
If th e AC m ain s voltage or frequen cy in dicated on your Nº390S is  
in correct, please con tact your local, auth orized Mark Levin son  
dealer or distributor.  
Th e Nº390S can easily be powered by a n orm al 15-am pere AC  
m ain s lin e. If oth er devices are also powered from th e sam e AC  
lin e, th eir addition al power con sum ption sh ould be taken in to  
accoun t.  
A Quick Start . . .  
We recogn ize th at m an y people are un derstan dably eager to begin  
listen in g to th eir n ew com pon en ts, an d th at readin g th e m an ual  
is often don e (if at all) at a later tim e—perh aps wh ile listen in g to  
m usic with th e n ew product itself. We stron gly recom m en d th at  
you read th is m an ual th orough ly, as th e Nº390S CD Processor  
in corporates m an y un usual features th at en h an ce its operation .  
Fortun ately, we can h elp you get som e m usic up an d run n in g on  
your system quickly, so th at you m ay begin en joyin g your n ew  
CD player wh ile readin g m ore about it. Th e goal h ere is sim ply to  
m ake som e m usic as quickly as possible. Th e followin g procedure  
assum es th at you h ave a relatively con ven tion al system an d it is  
already con n ected with th e exception of th e Nº390S (e.g.,  
pream plifier to power am plifier, to speakers, etc.).  
1. Turn off your associated components.  
Th is m in im izes th e opportun ity for a m om en tary electrical  
surge disturbin g your system wh ile m akin g con n ection s. If  
you h ave a large power am plifier, allow its power supply to  
fully disch arge before proceedin g (wh ich m ay take as lon g as  
several m in utes, depen din g on its design ).  
10  
2. Remove the transport screw from the bottom of the Nº390S.  
If you h ave n ot don e so already, rem ove th e kn urled tran sport  
screw from th e bottom of th e Nº390S n ow. Be sure to save it  
an d all packin g m aterial for possible future use. (Shipping the  
Nº390S without proper packing material and without the transport  
screw in its proper position may cause damage to the unit that  
would not be covered by the warranty.)  
3. Connect the Nº390S to AC pow er.  
Con n ect th e AC cord to th e Nº390S at th e receptacle on th e  
rear pan el, an d th en to your AC outlet. Th en turn on th e  
power switch just above th e AC power receptacle. (Th e  
in tern ation al sym bol for “on ” is a sin gle vertical lin e: |. “Off”  
is sym bolized by a circle: O.) Th e Nº390S will take a few  
m om en ts to in itialize an d will th en be ready to use.  
4. Connect either the XLR or the RCA analog outputs on the  
Nº390S to an appropriate input of your preamplifier.  
Wh en properly im plem en ted, balan ced in tercon n ection via  
XLR connectors and high quality balanced cables offers superior  
perform an ce, an d is preferred to sin gle-en ded RCA  
in tercon n ection . Both sets of outputs on your Nº390S h ave  
been optim ized to en sure m axim um com patibility in a wide  
ran ge of system s. (Note that you should never connect a line-level  
component such as a CD player to a phono input on a preamplifier.  
Although no damage is likely to result to either CD player or  
preamplifier, the sound will be badly distorted and the volume may  
be much louder than you expect.)  
4a. If going direct from the Nº390S to an amplifier!  
See Special Functions setup on page 47 to set th e Nº390S to  
variable output m ode.  
5. Power up the rest of the system, leaving the power amplifiers  
for last.  
Always turn th e power am plifier(s) off first, an d on last. Th is  
good h abit m in im izes th e opportun ity for un expected tran -  
sien ts to be passed to your loudspeakers. An oth er good h abit  
is to reduce th e volum e on your pream plifier to m in im um  
value before you restore power to th e system . Wh en th e  
Nº390S is in its variable pream p m ode, it powers up at a low  
volum e to m in im ize sudden ch an ges in volum e.  
6. Load a disc in the draw er and press Play; slow ly raise the  
volume on your preamplifier.  
Con gratulation s! You sh ould n ow be able to en joy your  
favorite m usic wh ile readin g th e rest of th is m an ual. (Please,  
do read the rest of this manual.)

Break-in Period  
Alth ough your Mark Levin son Nº390S CD Processor delivers  
outstan din g perform an ce straigh t out of th e box, you sh ould  
expect to h ear it con tin ue to im prove as it reach es its n orm al  
operatin g tem peratures an d its various com pon en ts “break-in .” It  
h as been our experien ce th at th e greatest ch an ges occur with in  
th e first 300 h ours, as th e Nº390S reach es th erm al equilibrium  
an d capacitors becom e fully form ed. After th is in itial break-in , its  
perform an ce will rem ain quite con stan t.  
Th e on ly exception to th is rule is if power is rem oved from th e  
un it for m ore th an a few m in utes, allowin g it to cool down .  
Depen din g on th e degree of coolin g in volved, you sh ould expect  
a brief warm -up period before th e Nº390S’s soun d quality is at its  
best. Un less your Nº390S was allowed to becom e quite ch illed,  
subsequen t th erm al re-stabilization sh ould n ot take lon g.  
Special Design Features  
Con gratulation s on your purch ase of th e Nº390S CD Processor.  
Th e design team is con fiden t you will en joy th e outstan din g  
perform an ce of th e Nº390S for m an y years. In case you are  
in terested in tech n ical details, wh at follows is a brief outlin e of  
som e of th e key tech n ologies in your n ew CD player.  
A New Generation  
Th e task of a CD player is easy to defin e: it m ust recover th e  
correct data from th e disc an d con vert th at data to a series of  
an alog voltages with n eith er am plitude n or tim in g errors  
(som etim es called “jitter”). As sim ple as th is soun ds, ach ievin g it  
in reality h as been extrem ely difficult—as eviden ced by th e  
sign ifican t son ic differen ces between various CD players.  
Con ven tion al CD player design depen ds h eavily on th e quality of

Th e Mark Levin son Nº390S leaps beyon d con ven tion al digital  
audio tech n ology by em ployin g a proprietary, closed-loop jitter-  
reduction system in con jun ction with a double speed CD-ROM

part-per-m illion accuracy, the digital signal is re-clocked im m ediately  
before its con version to an alog, elim in atin g tran sport-related jitter

In effect, th e design of th e Nº390S turn s th e accepted status quo on

Digital Servo Control  
Th e laser m ech an ism used in th e Nº390S uses all digital servo  
con trols of its operation s. Critical fun ction s such as focus an d

Digital Input/Output  
Versatility  
Th e Nº390S CD player in corporates two digital in puts, allowin g  
two extern al digital sources such as a laser disc player an d digital  
cable radio to ben efit from th e excellen t digital processor  
in corporated with in . Th e two m ost com m on digital in terfaces are  
supported for th e widest com patibility: EIAJ (som etim es called  
TosLin k™”) an d S/PDIF coaxial, via an RCA con n ector.  
Two h igh quality digital output con figuration s are also supported  
in th e Nº390S. A n ew com plem en tary driver for th e balan ced  
AES/EBU electrical output delivers outstan din g perform an ce to th e  
h igh quality XLR con n ector. A sin gle-en ded S/PDIF electrical  
output is also provided via an RCA con n ector. Th ese digital  
outputs m ay be used to feed th e in put of digital recorders or an  
outboard digital processor, an d th ey both ben efit from th e closed-  
loop jitter reduction circuitry described above. (In effect, th ey

All digital in terfaces h ave been carefully optim ized to deliver th e

result, th e Nº390S perform s optim ally with an y digital processor,  
with out h avin g to resort to tech n iques wh ich would lim it its

Industrial Design  
Th e Nº390S sh ares th e h an dsom e in dustrial design of oth er Mark  
Levin son com pon en ts such as th e Nº380 pream plifier. Th e

In keepin g with its soph isticated design , th e Nº390S also

Con trastin g stron gly with th e bulky, plastic drawers com m on ly

Convenience Features  
Too often, high performance CD players have eschewed convenience  
in th e h opes of seem in g m ore “perform an ce-orien ted.” Wh ile th ere  
were good argum en ts for such a “m in im alist” design in th e days  
of an alog turn tables, th e tim e is lon g gon e wh en th e audioph ile  
needed to give up operational convenience for m usical perform ance.  
After all, con ven ien ce features in a digital product are largely a  
m atter of writin g appropriate software, an d h ave n o affect on th e  
quality of th e digital data itself.  
Th e Nº390S supports a variety of custom program m in g option s,  
in cludin g “delete program m in g” wh erein selected tracks are  
om itted from th e play list. Th is allows th e user to skip th e on e or  
two son gs on an oth erwise good disc th at h ave been overplayed  
ad nauseam. Th e Nº390S will rem em ber such program s for  
th ousan ds of discs, sh ould you wan t to save th at m an y program s.  
Communications Links  
As with all Mark Levin son 30-series com pon en ts, th e Nº390S

so th at a CD can be en joyed. Even a soph isticated system with  
m an y com pon en ts can th us offer on e-button sim plicity of

In sh ort, th e Mark Levin son Nº390S establish es a n ew stan dard for  
perform an ce an d practicality am on g h igh en d CD players an d  
sh ould be audition ed by an yon e wh o desires th e fin est in digital

Fully Balanced Design  
Th e Nº390S is fully balan ced in both th e an alog an d digital  
dom ain s. In form ation from th e disc an d sin gle-en ded digital  
in puts are im m ediately con verted to balan ced sign als an d routed  
to balan ced DACs by way of an LVDS (Low Voltage Differen tial  
Sign al) tran sm ission lin e. Th is design tech n ique, borrowed from  
separate Mark Levin son digital processors, preserves th e faultless  
tim in g of th e digital audio sign al m ade possible by our Closed  
Loop Jitter Reduction (CLJR) system m en tion ed earlier in th is  
m an ual.  
An Arlon 25N® prin ted circuit board provides th e foun dation for  
th e critical an alog audio circuit. First used in th e Nº32 Referen ce  
Pream plifier, this superior m aterial offers superb dielectric properties  
an d h elps th e Nº390S ach ieve rem arkable perform an ce with  
com plex audio sign als.  
Design of th e fully balan ced DAC/an alog output m odule follows  
th e Mark Levin son tradition of rigorous com pon en t selection . An  
un usual h ybrid design approach in corporatin g both advan ced  
Surface-Moun t an d “th rough -h ole” tech n ologies, allows us to  
utilize th e optimum part at each location in th e circuit, with out  
th e con strain ts on parts selection n orm ally associated with  
tradition al PCB assem bly practices. Every active device h as been  
pain stakin gly selected for top tech n ical perform an ce, with fin al  
selection s of top perform in g devices determ in ed by n um erous,  
con trolled son ic evaluation s.  
Advanced Digital Filter  
Techniques  
Just as with Mark Levin son separate Digital Audio Processors, such  
as our Nº30.6 Referen ce, th e Nº390S in corporates advan ced digital  
filter techniques carefully chosen to optim ize the sonic perform ance  
of its on-board digital processor. Whether playing a CD, or decoding  
a digital sign al received th rough an auxiliary in put, sam ple depth  
is in creased to 24 bits an d sam ple rate in creased to 352.8kHZ or  
384kHz (in put rate depen den t) prior to con version to an an alog  
sign al. Th is soph isticated “processin g” of th e digital sign al before  
con version (referred to variously as “un con version ”, “upsam plin g”,  
or “oversam plin g”) is a fun dam en tal con tributor to th e excellen t  
soun d ach ieved by all Mark Levin son digital processors. Th e  
Nº390S con firm s its in tern al con version rate on its fron t pan el  
display each tim e a disc is loaded, or an auxiliary in put is ch osen  
an d locked.  
15  
Th e Nº390S also in corporates High Defin ition Com patible  
Digital® decodin g to take full advan tage of th e resolution avail-  
able from HDCD en coded 16-bit CDs. Th e HDCD form at retain s

available on th e disc.  
Digital to Analog  
Conversion  
Digital to an alog con version with in th e Nº390S is perform ed at an  
extraordin arily h igh level an d features a Mark Levin son -developed,  
balan ced im plem en tation of th e An alog Devices AD1853—a n ew  
class of m ulti-bit Sigm a/Delta DAC devices deliverin g superb  
tech n ical perform an ce. In addition to its un usual m ulti-bit  
arch itecture an d un like typical Sigm a/Delta devices, th e AD-1853  
h as a differen tial curren t output stage, wh ich allows us to optim ize  
th e critical curren t-to-voltage(I/V) con version stage with dedicated  
operational amplifiers possessing superlative rise time and bandwidth  
ch aracteristics. Followin g th is, a n ew active an alog filter circuit,  
im plem en ted in a differen tial am plifier, sum s both h alves of th e  
balanced signal and provides superb com m on m ode noise rejection  
in addition to its outstan din g filter ch aracteristics.  
This approach to the Digital-to-Analog circuit block yields distortion  
and noise levels that are extraordinarily low and contributes greatly  
to th e n atural soun d of th e Nº390S.  
Balanced Analog  
Volume Control  
Rath er th an use th e digital atten uator on -board th e DAC, th e  
Nº390S incorporates a fully balanced analog volum e control sim ilar  
to th at foun d in Mark Levin son separate pream plifiers. Wh en  
activated (by turn in g on th e variable output fun ction un der  
setup: sound), th e output of th e Nº390S m ay be atten uated in  
precise 0.1dB steps th rough m ost of th e ran ge. Sign ifican tly, th e  
Nº390S m ain tain s th e full perform an ce of its rem arkable DACs at  
all volum e levels—som eth in g im possible with digital volum e  
con trols, regardless of wh at tech n iques m ay be em ployed to m ask  
th e son ic con sequen ces of th is design approach .  
State-of-the-Art  
Output Buffer  
Th e balan ced discrete output buffer circuitry used in th e Nº390S  
em ploys th e sam e topology used in th e rem arkable Mark Levin son
