Multi Channel Amplifiers
6.
RCA
Input
Jacks
RCA Input
jacks are for use with source units having RCA or low level
output. source units with an output signal level of minimum 200mV may
be used. (see installation wiring diagram)
7.
Sub-Woofer RCA Input
Jacks (570-AZR700X5 only)
sub-Woofer jack are for use with the source unit with an RCA or low level
output. High level-in Adapter may be used with sub-Woofer input
8.
Auto Sensing (AS)
selector switch
When the As level switch button is sticking up for “lOW”; the amplifier is
set for low level input. The amplifier ReM connection is required to Remote
Turn-on from the source unit
When the As level switch button is pushed in for “Hi”; the amplifier is set
for high level input. use the High level in Adapter for the RCA terminals.
The Amplifier has a dC OFFseT turn on function for High level input, auto
sensing Channel A only. The ReM connection to the source unit is not
required for high level input.
9.
GAIN
Control
use the
GAIN
Control to fine-tune the input sensitivity of the amplifier to
the source unit’s output level. The operating range is from Min to MAX.
This is nOT a volume control!
10.
Crossover Filter
(570-AZR170X & 570-AZR400X4 only)
These controls allow control over the frequencies played for the rear
channels. There is an option for low pass Filter, Full Range or High pass
Filter.
11.
Frequency Control
(570-AZR170X & 570-AZR400X4 only)
used with the Crossover filter switch; the crossover frequency can be tuned
from 50Hz to 750Hz by the frequency dial in either lpF or HpF mode.
12.
Power
indicator
The led indicates the amplifier is functioning properly when the led is lit.
13.
Protection
indicator
The led will light up red and will flash if there is a fault detected by the
amplifier. disconnect the amplifier. Check and fix the connections to resolve
the fault condition.
