The pre-fader signals (monitor buses) remain operative. When MUTE is pressed, the corresponding control LED illuminates. m The channel fader controls the channel signal level in the main mix. 2.1.1 Input section [181 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. H9l 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. PMXIOOO: This does not apply to the mono/stereo combination channels S/6 and 7/8. [20l 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. [211 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. [221 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 S/6 and 7/8. [231 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. C PMX3000/PMXS000: Please note that you need to set the A/B selector [T] to A (1/4”) or B (RCA) when you connect a signal to the input. [241 PMX3000/PMX5000: Each of the two stereo channels has two monitor controls (MON 1/2) and a LEVEL control [251. Like the other channels, they also feature a PFL switch. [251 Instead of a fader this channel has a rotary LEVEL control. [26l 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. [271 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 [7T1 and the main signal at OUTPUT B [7Q] (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/PMXS000: MAINL/MAINR. In position MAIN MIX, the mixer works as a stereo amplifier. MON I/MONO. In this mode the monitor 1 signal is present at OUTPUT A [HI and the main signal at OUTPUT B [70] (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 8.0 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 O. Please note that the power delivered to the speaker connected to OUTPUT B in BRIDGE ...
