. Connect the signal source whose output needs 

to be amplified.

Here you will connect an output of your mixing console, your HiFi preamp or 
another signal source.

Our rack mixing console EURORACK PRO RX1602, with its eight mono-usable 
balanced stereo channels, is an ideal choice for signal processing and 
source selection.

The connections for both channels are laid out as RCA, XLR and ¼" TRS stereo 
connectors. The cinch inputs are intended for use with outputs laid out as 
unbalanced signals with a -10 dBV line signal level. Because these inputs 
are more sensitive than others, you can directly connect a CD player or a 
DAT recorder. Of course this input can also be used for connecting mixing 
consoles and similar equipment.

The XLR and ¼" TRS stereo connectors are laid out balanced, but they too can 
of course be used to connect unbalanced signals. Their sensitivity is +4 dBu 
(also see ch. 4).

Generally speaking, you should choose balanced over unbalanced signals in 
order to guarantee the highest noise protection.

Due to safety considerations, the inputs can not be used in parallel. 
However, if you are using cinch and XLR or ¼" TRS connectors 
simultaneously, the cinch input is given preference, and the other signal 
is muted.
If you wish to use the A500 in mono-bridged mode, 

[7]

. These are the inputs for channel 2.

The 

[8]

STEREO/BRIDGED MONO switch is used to toggle between the two 

operating modes of your A500.

[9]

 and BRIDGED MONO: These are the speaker 

connectors of your A500 laid out as ¼" TS mono connectors. When in 
mono-bridged mode, only use the BRIDGED MONO output. 

In addition to XLR or ¼" TRS connectors, you can also use binding posts for 

[10]

connecting speaker cables. When in mono-bridged mode, make sure to 
connect your cables to both middle connectors–as shown on the unit itself.

[11]

. Before connecting the unit to the 

mains, please check if the voltage selector corresponds to your local voltage. 
When replacing fuses, you should only use fuses of the same type and rating. 
With some units, the fuse switch can be put into two different positions in 
order to select between 230 V and 120 V operation. Please bear in mind: 
If you wish to use your equipment outside of Europe running on 120 V, 
you will have to use a fuse with a higher Ampere value.

The mains connection is made via a standard 

[12]

IEC RECEPTAClE. A matching 

cable is enclosed.

[13]

.

In this mode, both channels run independently with a separate input signal. 
Connect passive loudspeakers, preferably high-quality studio monitors, such 
as the BEHRINGER TRUTH B2031P. Set the STEREO/BRIDGED MONO switch 

[8]

 to 

“STEREO” to enable stereo mode.

Two independent mono signals, e.g. instrument signal and monitor mix

Bi-amp operation, with the bass signal on channel 1 and the treble signal 

on channel 2

In this mode, the voltages of both channels are added up and routed to just 
one loudspeaker. This results in a doubling of voltage, quadrupling of the peak 
power value and roughly trippling of the continuous power output on a single 
channel. The input and the gain control on channel 1 are used in mono-bridged 
mode. Thechannel 2 control elements are not used. ATTENTION: To avoid 

Use this operating mode to feed the output of both channels into a single 4-Ohm 
load. Set the STEREO/BRIDGED MONO switch 

[8]

 to “BRIDGED MONO.”
