2. CONTROL ELEMENTS
The FX control determines the signal level sent from each
channel to the built-in effects processor; this signal is also
present at the FX SEND jack (see ).
The PMX5000 has two FX controls (FX 1 and FX 2), so that
you can use two effects simultaneously. Accordingly, the
PMX5000 also has two effect aux buses, which have one
output jack in common (see and ).
+
Please note that the effects processor signal will be
inaudible, as long as the FX TO MON/MAIN controls
, , are set fully counter-clockwise.
The PAN(ORAMA) control determines the position of the
channel signal in the stereo main mix.
The BAL(ANCE) control for the stereo channels
corresponds to the PAN control for the mono channels. It
determines the relative volume of the left and right input
signals before they are routed to the stereo main output.
PMX3000/PMX5000: When you press the PFL button (Pre
Fader Listening) the left LED shows the pre-fader
input gain of the channel. Adjust the optimum input gain (0
dB) with the TRIM control . When PFL is on, the corres-
ponding LED illuminates.
If the LEVEL SET LED
is illuminated constantly, the
signal is within the optimum operating level range. However,
if the CLIP LED indicates that the input gain is too high, you
should reduce the level slightly with the TRIM control. The
CLIP LED should never be illuminated all the time, only with
signal peaks.
The MUTE switch mutes the channel in the main mix. The
pre-fader signals (monitor buses) remain operative. When
MUTE is pressed, the corresponding control LED illuminates.
The channel fader controls the channel signal level in the
main mix.
2.1.1 Input section
Each mono input channel is equipped with a balanced
microphone input (XLR connector) which provides
+48 V phantom power for condenser microphones at the
touch of a button (see rear panel).
PMX1000: The two stereo channels 5/6 and 7/8 have an
additional balanced XLR microphone input with +48 V
phantom power.
+
Be sure to switch off your audio system before you
activate the phantom power supply to protect your
monitor speakers from switch-on thumps.
Each mono input features one LINE IN connector (1/4"
jack), which can be used with either balanced or
unbalanced signals.
+
Please remember to use either the microphone or
the line input on a specific channel. Never use both
at the same time!
+
When you connect a mono line signal to a stereo
channel, always use the left input. The mono signal
will then be reproduced by both sides equally.
+
PMX1000: This does not apply to the mono/stereo
combination channels 5/6 and 7/8.
INSERT I/O. Insert points or simply inserts are dynamic
processors or equalizers. They are pre-fader, pre-EQ and
pre-MON/FX SEND. Unlike reverb and other effects, which
are usually added to the dry signal, dynamic processors
usually process the entire signal. So, aux send buses are
not the best solution. Dynamic processors need to be
inserted directly into the signal path. Once processed, the
signal then returns to the mixing console at the same point
where it left. Signal interruption takes place only if a plug is
inserted into the corresponding jack (1/4 " stereo plug: tip =
signal output, ring = input). All mono input channels are
equipped with inserts.
The stereo channels have a TRIM control for gain
adjustment, with the input sensitivity ranging from +20 to
-20 dB.
PMX1000: The stereo channels 5/6 and 7/8 feature an
additional XLR connector for microphones whose gain
can be set from 0 to +40 dB.
Each stereo channel has two line-level inputs (1/4" jacks)
for the left and right channels. If only the jack marked “L” is
used, the channel is mono. The signal will then be
reproduced on both sides.
+
PMX1000: This does not apply to the mono/stereo
combination channels 5/6 and 7/8.
PMX3000: The stereo channels 9/10 and 11/12 are equipped
with additional RCA connectors.
PMX5000: The stereo channels 13/14 and 15/16 are
equipped with additional RCA connectors.
+
PMX3000/PMX5000: Please note that you need to set
the A/B selector to A (1/4") or B (RCA) when you
connect a signal to the input.
PMX3000/PMX5000: Each of the two stereo channels has
two monitor controls (MON 1/2) and a LEVEL control .
Like the other channels, they also feature a PFL switch.
Instead of a fader this channel has a rotary LEVEL control.
The phantom power supply provides the voltage necessary
for the operation of condenser microphones. Use the
PHANTOM switch to activate the supply for the XLR
connectors of the input channels. The +48 V LED will
illuminate when phantom power is on. In most cases,
dynamic microphones can still be used, as long as they are
connected in a balanced configuration. If in doubt, please
contact the manufacturer of your microphone!
+
With phantom power switched on, you must never
connect microphones to the console (or to a stage/wall
box). Also, be sure to mute the monitor/P.A. speakers,
before you turn on the phantom power supply. After
switching on, please allow the system to stabilize for
about one minute, before you adjust the input gain.
+
Caution! Never use unbalanced XLR connectors (pins 1
and 3 interconnected) on the MIC input jacks, if you are
going to use the phantom power supply.
The AMP MODE switch determines the mode of operation
of the PMX amplifier stage:
PMX1000:
MAIN: In the “MAIN” position the mixer works as a stereo
amplifier.
MON: In this mode the monitor signal is present at OUTPUT A
and the main signal at OUTPUT B (both are mono).
BRIDGE (bridged mono mode): In BRIDGE AMP MODE
the output power of OUTPUT A is added to that of OUTPUT
B, i.e. OUTPUT B delivers twice its normal output power .
PMX3000/PMX5000:
MAIN L/MAIN R.
In position MAIN MIX, the mixer works as
a stereo amplifier.
MON 1/MONO. In this mode the monitor 1 signal is present
at OUTPUT A and the main signal at OUTPUT B
(both are mono).
BRIDGE (bridged mono mode): In BRIDGE AMP MODE
the output power of OUTPUT A is added to that of OUTPUT
B, i.e. OUTPUT B delivers twice its normal output power .
+
In BRIDGE mode, always connect only one loudspeaker
with an impedance of at least 8 W to the OUTPUT B jack!
Please note that OUTPUT A must NEVER be used in
BRIDGE mode!
+
In all other operating modes, the minimum impedance
of the speaker must not fall below 4 W.
+
Please note that the power delivered to the speaker
connected to OUTPUT B in BRIDGE AMP MODE is
