Quick Start Guide
Controls
(EN)
(1) The POWER switch is used to power up the
A500. The POWER switch should always be in
its "Off " position when you connect the unit
to the mains.
POWER LED lights up as soon as you power up
the A500.
(2) Each channel features a volume control. Use it
to adjust gain on your A500. Both volume
controls should be turned all the way to the
left whenever you power the unit up or down.
If an active signal is present on the input,
turning the volume down will protect your
speakers and your ears from unwanted "pops"
or transients.
(3) The PROT LED lights up whenever the
protective circuitry mutes the speaker output.
Please turn your A500 off immediately
whenever this LED is lit.
(4) The high-precision power indicator gives out
current signal strength.
(5) The CLIP LED lights up when the signal is
distorted. Should distortion occur, reduce the
input level, so that the CLIP LED no longer
lights up.
(6) CHANNEL INPUT 1 (MONO). Connect the
signal source whose output needs to
be amplifi ed.
(7) CHANNEL INPUT 2. These are the inputs for
channel 2.
(8) The STEREO/BRIDGED MONO switch is used
to toggle between the two operating modes
of your A500.
◊
Please power the A500 down using the
POWER switch each time you change the
operating mode. Similarly, only connect/
disconnect speaker connectors if the
A500 has fi rst been powered off !
(9) OUTPUT 1, OUTPUT 2 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.
(10) In addition to XLR or ¼" TRS connectors,
you can also use binding posts for
connecting speaker cables. When in mono-
bridged mode, make sure to connect your
cables to both middle connectors–as
shown on the unit itself.

(12) The mains connection is made via a
