Thank you for purchasing the Luxi Electronics® AMP-1002 
compact power amp.  Please read through this manual before 
using the product. 
 

How the product functions: 

This product has 4 audio inputs: No 

1 is a stereo balanced/unbalanced line input at +4 dBu level, No 2 
is a mono unbal mic input at -20 dBV level, No 3 and No 4 each is 

a stereo unbal line input at -10 dBV level.  The No 1, 3 and 4 line inputs are equalized in level, then 
these 3 left signals are mixed together, and 3 right signals are mixed together, controlled by the Line 
Gain pot, then the volume control.  The No. 2 mic input signal is equalized in level, controlled by the Mic 
Gain pot, not controlled by volume control (to prevent feedback from speakers to mic), split evenly to 
left and right channels, and mixed to the main left and right channels.  Volume control is a standard 10 
V reference voltage, external 10k ohm pot analog control for both left and right channels.  See the block 
diagram below. 

 

 

Power options: 

This product draws power from an external 24 V 3 A power supply sold separately (Luxi 

P/N 69-008-03).  

Do NOT plug the power supply connector into any other connectors; this could cause 

permanent damages to the product and void the warranty.

 

 

Captive screw plug termination: 

The captive screw plugs for power, audio, 

speakers and volume controls are supplied 
with the unit.  Separate the wires about 1” 
(2.5 cm) long; strip off the wire insulation 
precisely 3/16” (5 mm) from the end.  
Identify the positive and negative leads for 
power; Luxi power supply uses red wire for 
the positive wire.  If not sure, use a multi 
meter to verify. 

 Reversing power polarity 

could cause permanent damages to the product and void the warranty.

 

 

Mounting options:

 Luxi has the under desk mount (Luxi P/N 78-002-01) or the MediaHub table tanks 

sold separately; the product also fits many other mounting hardware from Extron, Middle Atlantic, etc.  
Only use the type 4-40, 3/16” (5 mm) long screws supplied with the mounting hardware to screw onto
