F) Signal led
This LED shows the presence of signal at the
amplifier's inputs and is dependent on the position
of the LEVEL control.
G) Cooling air outlet grilles
Fan cooling permits airflow through the most
vital parts of the amplifier. Since the airflow finds its
way out through these grilles, keep them as clean
and dust-free as possible to assure proper cooling.

A) Speaker outputs
T e r m i n a l

provided to connect
the speakers. Both
70V
and
c o n n e c t i o n s
available.
More examples on
Appendix D.
B) Inputs
An XLR input is connected in parallel to an XLR
output for each amplifier. For more information
consult Appendix B.
Nominal input impedance is 20K ohm for
balanced use and 10K ohm for unbalanced use.
Polarity complies with AES14-1992 (ANSI
EN
S4.48-1992) and therefore pin assignments are:
1 = GND (Ground)
2 =(+) non-inverted signal
3 = (-) inverted signal
Terminal Block balanced input signal are also
available for each channel, in parallel with the XLR
inputs.

C) Input mode switch
OUTPUT
This switch allows the selection for the input
configuration mode: stereo, parallel or bridge.
BRIDGE
1 00V
Typically the amplifiers are used in stereo
1 40V
200V
mode, where the input to channel A feeds channel
A and the input to channel B feeds channel B.
1 00V
Parallel mode allows feeding both channels
with the signal plugged into channel A. Channel
B's input is disconnected in this mode.
Use the Bridge mode to use the power of both
amplifiers for one single output. For more
information consult Appendix A.
In the figure above, the Input Mode Switch can
be seen located between the two XLR input
connectors.
D) Mains led
The amplifier is plugged into the mains by way
of a power cord complying with the IEC standards.
The IEC-type detachable power cord features
three isolated cables, color code being brown
(live), blue (neutral) and yellow-green (earth).
E) Fan inlet grilles
Like for the front outlet grilles, keep clean and
dust-free to assure free air intake for proper
cooling.
