RS232 
 
All functions of the Atlas can be controlled and monitor
ed via RS232, using the DB9 connector.  As long as the 
rear panel power switch in turned on, the RS232 circuitry  is always active, thus allowing the Atlas to be taken 
out of  STANDBY  via RS232.  Refer to Appendix C for more information on using RS232. 
 
Please refer to Appendix D for additional information.

Appendix A  Troubleshooting Guide 
 
If the Atlas should function abnormally during operation, pleas
e review the items in the following checklist.  Please 
be sure to thoroughly check all other connected components such as speakers, preamplif iers, as well as cables. 
 
Symptom Possible Cause(s) Remedy 
No power or front panel 
lights and no sound. Power cable is not inserted 100% into AC 
input connector. Ensure that the AC cord is inserted all the way 
into the Atlas and that the wall outlet is active. 
 Power Supply fuse is open. Replace with same type and rating ONLY 
 Rear panel fuse is open. Replace with same type and rating ONLY. 
 Circuit breaker is open (AC outlet). Check the AC outlet circuit breaker and reset, 
if necessary, or contact your dealer. 
 Module rail fuse is open.  See “Display codes” section below. 
No audio output. Input Jack not correctly mapped. Ve rify that the Input ja ck that is physically 
being used is the same one that is shown on 
the display when the INPUT button is 
pressed.. 
 Mute is active Unmute the Atlas. 
 Overheating The amp module(s)  may be overheated.  Shut 
down the Atlas until it cools. An external fan 
may be necessary. 
 Amp module fuse is open. Replace with same type and rating ONLY. 
Hot/Warm Normal  operation  
 
 
 
Display Codes 
 
If the Atlas displays the following message in the display upon power up\
: 
 
LEFT FUSE PLUS  The left channel plus fuse is  blown.  Replace with same type and value. 
LEFT FUSE NEG  The left channel minus fuse is bl own.  Replace with same type and value. 
RITE FUSE PLUS  The right channel plus fuse is blown.  Replace with same type and value. 
RITE FUSE NEG  The right channel minus fuse is  blown.  Replace with same type and value. 
 
HOT Heatsink Temperature over 85 C.  Turn atlas  off to cool it.  Research reason for overheating. 
 
OC DC offset on the output.   
 
If one of these messages is in the display on porer up, t he Atlas will not come out of STANDBY until the error is 
corrected.
