Current Audio AMP-1270 - Product Information; Supplied Accessories; Amplifier Specifications; Glossary of Audio Terms

Thank you for purchasing a Current Audio Multi-Channel Amplier.
Please read this manual thoroughly before making any connections or applying AC power. This manual
applies to both the AMP-1270 and the AMP-870. The AMP-870 has fewer channels (eight) compared
to the AMP-1270 with twelve channels.
Follow the instructions in this manual. It will allow you to obtain the maximum performance and listen-
ing pleasure from your new amplifier.
Please retain this manual to use as a future reference.
Supplied Accessories
The box includes the following equipment and accessories:
• (1) Multi-Channel Digital Amplifier (AMP-1270 or AMP-870).
• (1) Grounded Power Cord for US. Europe uses a 220VAC non grounded cord.
• (1) Set of right angle Rack Mount Brackets

Glossary of Terms
Amplier - An electronic device for increasing the amplitude of low level electrical signals, used chiefly in sound
reproduction.
Auto Sensing - Amplifier will only be turned ON when a low level music signal is detected. It will turn off when
no signal is present after about a 10 minute delay. The delay prevents any unwanted annoying cycling of amp.
Bridging - Amplifier bridging is simply using 2 channels of an amplifier to drive a common load for more power.
Channel - This refers to one input or output of a stereo zone.
Continuous Power Out - The ability of an amp to output its full RMS power continuously.
Frequency Response - Range over which an audio component can effectively produce a useable and fairly uni-
form, undistorted output signal.
Line Level - A low level signal like a CD output that must be amplified to produce a usable audio sound level for
speakers.
Loop Out - A duplicate low level input signal that can be used to power additional amps to expand your zones.
THD - Total Harmonic Distortion; specification that compares the output signal of the amplifier with the input sig-
nal and measures the level differences in harmonic frequencies between the two.
Zone - Two channels make one Zone, sometimes referred to as Room in multi-zone/room amplifiers.
