Output module for PM100 modular mixer.

Discontinued - this product is no longer available.

The master module contains all the electronics required for the various summing amplifiers, output stages, VU meters, crossfade control circuits, etc. The majority of connections are on the rear of the unit. Monitoring The monitoring section of the PM-100 is very comprehensive. Visual monitoring is provided by a stereo 24 segment led bar graph meter. AUX EXT CONTROL SENSITIVITY ATTENUATION A.V.O. ON AUX 1 MASTER AUX 2 MASTER PROG TO AUX 2 PFL SELECTED ZONE CUE TO BOOTH BOOTH MON Two powerful stereo headphone amplifiers are incorporated designed to drive headphones of 32 ohms or greater. Connections are via 3 pole jack sockets. The main phones output is located at the top right of the front panel, the second output is on the rear panel. The meter and the main phones output are both connected to the same signal so what you see is what you hear. Mon Bal (monitor balance) It is important that the function of this control is fully understood. The output from this control is fed to the RET MASTER MONO PM-100 PGM SPLIT PFL BAL PHONES monitoring section (the led bargraph meter and via the PHONES volume control to the main phones output). With the control turned fully clockwise towards PFL, the meter will read the PFL signal of any channel that has its PFL button depressed, or the sum of channels if more than one is selected. As a further visual aid a red led beneath the meter also illuminates if any PFL button is depressed. If no PFL buttons are depressed the meter reads the main output level which is dependent on the MASTER control setting. Turning the monitor balance control counter clockwise towards PGM feeds the programme signal (pre master) to the monitoring section. Therefore the CONTOUR A CROSS FADE FORMULA SOUND B PUNCH operator can quickly pan or mix between the PFL and program. It also facilitates the monitoring of a recording being made with the master turned down. A SPLIT button is also provided (which is the preference of some operators). This provides a mono PFL signal on one side of the monitor system and a mono program signal on the other side. The Mon Bal sets the balance of the two signals in this situation. Practice and use will determine the best mode of operation. A.V.O. (Automatic Voice Over) This function is enabled by the illuminated push button A.V.O. ON. When turned on any microphone signal present will dim the music signals to allow talk over. The amount the music is dimmed is determined by the attenuation control. The adjacent sensitivity control sets the triggering level of the AVO system. AUX RET (Auxiliary Return) This is a basic stereo input configured to accept balanced or unbalanced input signals via 2 X 1/4" 3 pole jack sockets. (For unbalanced operation 2 pole jack plugs may be used). For mono operation feed equally into both inputs. The input impedance is >20K ohms balanced and 10K ohms unbalanced. This input is intended for simple no frills connection to the stereo buss for effects return etc. If more facilities are required it is normal to use an input channel. MASTER - This control sets the output level of the main balanced output available via 3 pole XLR connectors on the rear panel. This output is monitored by the main phones and VU meter when the MON BAL control is set to PFL and no PFL is selected. The VU meter is factory calibrated 0dB = 0dBu (775mV) MONO - An illuminated push button switch located below the master control allows the master output to be operated in mono mode. This switch only affects the main output. ZONE -The zone output is almost identical to the main output in all respects except that the signal is not available to the monitoring section and no insert sockets are provided. The output may also be used in mono or stereo as set by a rear mounted push switch located between the XLR sockets. AUX 1 MASTER - This master control adjusts the output level of the signals derived from the Aux1 sends on the input modules. The outputs are via 2 1/4" jack sockets a mono signal may be obtained by using the left output socket only. AUX 2 MASTER - This master control adjusts the output level of the signals derived from the Aux2 sends on the input modules. The outputs are via 2 1/4" jack sockets a mono signal may be obtained by using the left output socket only. AUX 2 OPTIONS An illuminated push button switch located below the AUX 2 Master control (PROG TO AUX 2) routes the programme mix to the AUX 2 output. This is provided so that the AUX 2 output can be used as yet another zone output should this be required. Alternatively if the second phones output is set (via internal jumpers located on PC-344) to listen to the AUX 2 output a second monitoring system will then be available which is totally independent of the main phones output. This would provide for a second operator to have independent monitoring facilities. In this mode AUX 2 jumper links on the channel modules would normally be set to pre fade. The AUX 2 master control would set the phones level. BOOTH - This control adjusts the level of the booth output which is a mix of music channels only. The outputs are via 2 1/4" jack sockets. A mono signal may be obtained by using the left output socket only. CUE TO BOOTH - An illuminated push button switch located below the booth control. When depressed this switch routes the mains phones signal to the booth output, so therefore all the phones monitoring facilities become available on the booth outputs. Operators should be aware that in this mode it is possible to have microphone signals present on the booth outputs which could be the cause of acoustic feedback. CROSSFADE The XF-A and XF-B busses are fed to the crossfade circuitry. The crossfader is a 45mm fader which can be used to smoothly fade between the XF-A and XF-B busses. The crossfade system uses studio quality V.C.A.'s (voltage controlled amplifiers) to Improve crossfader life and also ensure good attenuation at the ends of travel. Red and green leds positioned at the fader ends correspond to the XFA and XFB routing switch illumination colours which gives good visual routing status. CONTOUR A contour control is provided which allows the operator to adjust the crossfader characteristics to suit personal taste, from a gentle fade between A and B to a more aggressive fade towards the ends of the fader. PUNCH A fast momentary action push button is fitted to provide rapid switching effects. The action of this switch is to turn on both XF-A and XF-B busses irrespective of the fader position. Depending on how channels are routed to crossfader this can provide several effects for the creative D.J. INSERTS Insert sockets in the form of 3 pole 1/4" jacks are provided for the connection of external signal processing equipment. Located on the rear panel the connections are:- Tip = send (mixer output) Ring = return (mixer input) Body = common (ground) These sockets have switching contacts so that if a plug is not inserted the signal path is maintained. Insert sockets are provided for the following functions:- XFA left and right for the connection of filters etc. into the XFA signal chain. XFB left and right for the connection of filters etc. into the XFB signal chain. MIC left and right for the connection of signal processing equipment, compressors, limiters etc. into the microphone signal chain. Master Insert left and right for the connection of signal processing equipment into the main output chain. Individual microphone inserts are also provided on the input channel modules. RECORD OUTPUTS 2 pairs of gold plated phono sockets are provided for the connection of stereo recording equipment. One pair provides the complete programme mix; the other pair provides the mix of music sources only. AVO does not affect this output. All record outputs are unaffected by the master controls. SUB BASS OUTPUT A mono output via a 1/4" jack is provided for driving a sub bass loudspeaker system to enhance low frequency performance. The filter allows frequencies below 70Hz to pass through. An internal jumper located on PC-344 allows higher bass output if required. LIGHTING TRIGGER A mono fully floating transformer isolated trigger output is available on a 1/4" jack to provide safe connection to lighting equipment. PRIORITY A priority input with adjacent level trim control and control socket are provided to help comply with fire regulations. The fire alarm panel needs to provide a fully floating pair of contacts to join the two pins on the control connector. Internal jumpers located on PC-342 provide the option to mute all signals or leave mic signals active and intoduce the priority signal. The priority input may not be required if existing microphone inputs are to be used for evacuation. This will depend on local fire regulations.
