SIGNAL
LED
These green LEDs show 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) OUTPUT CONNECTIONS
Channel output connections to speakers is by binding
posts. PS-800 and PS-1400 models also provide Speakon
NL4 connections.
For the binding posts, polarity is clearly indicated by black
(–) and red (+) output terminals.
For the lower Speakon connector, pin assignments are:
Channel A : +1 / -1
Channel B : +2 / -2
Bridge : +1 / +2
For the Speakon situated on top, pin assignments are:
Channel B : +1 / -1
B) INPUTS
XLR and Jack inputs are connected in parallel.
Nominal input impedance is 20k ohm for balanced use and
10k ohm for unbalanced use.
Polarity complies with AES14-1992 (ANSI S4.48-1992) and
therefore pin assignments are:
1 or (Jack sleeve) = GND (Ground)
2 or (Jack Tip) = (+) non-inverted signal
3 or (Jack ring) = (–) inverted signal
C) INPUT MODE
This switch allows the selection of the input configuration
mode: stereo, parallel or bridge.
Typically the amplifiers are used in stereo mode, where the
input to channel A feeds channel A and the input to channel
B feeds channel B.
Parallel mode allows feeding both channels with the signal
plugged into channel A. Channel B's input isn’t
disconnected in this mode, therefore it can be used as a
link thru connection.
Bridge mode sums
both amplifier channels together, thus
doubling the output power. Refer to the “Bridge Mode
Operation” Appendix for further information.
D) INPUT SENSITIVITY SELECTOR
This selector allows to choose the input sensitivity 0.775V,
1.00V and 1.44V.
E) GROUND LOOP SELECTOR
The selector is used to avoid ground loops. Set the selector
in the “OFF” position when loops are detected.
F) MAINS LEAD
The mains lead is a connector type IEC320 terminated on a
plug.
If you need to cut off the plug to replace it for the type used
in your region, cable colour codes are brown (live), blue
(neutral) and yellow-green (earth). The appropriate fuse is
provided in the connector.
G) FAN INLET GRILLES
Like for the front outlet grilles, keep clean and dust-free to
assure free air intake for proper cooling.
