Discontinued - PM100 Universal Input Module with linear fader.

Sorry, we are no longer able to supply this product

(mic, stereo, line, phono - RIAA inputs)

This product is no longer available.

Input Sources The design of this module allows almost any input source to be used and further allows the operator to switch between any two input sources.

This is achieved by providing a balanced low impedance low noise microphone pre amplifier; a stereo RIAA equalised pre amplifier which also may be configured as a normal flat response line level input; and a normal line level input stage.

Input Connectors Rear panel mounted 1 - XLR Mic input socket, 1 - 3 pole jack insert socket (provides connection for external equipment into the microphone channel). Two pairs of gold plated RCA phono sockets are provided for the stereo inputs. Input A may be the RIAA input or a normal line input as selected by 2 internal jumpers. The B input may be a microphone input or a stereo line input as selected by a further internal jumper. Rear panel gain trims are provided to set the maximum gain available on any input.

INPUT SELECTION A front panel mounted toggle switch allows rapid selection of the A or B input. Red and Green led's provide clear visual indication of the input selected. Adjacent areas are prov ided to label the input sources.

GAIN A control allows the operator to compensate for variations in programme material. (See later section on gain)

PEAK A red led indicates when the peak signal level in the module is just below clipping. Three band equalisation

HF (High Frequency or Treble) This control provides +6dB boost - 20dB cut @ 10kHz with a shelving response.

MID (Middle Frequencies) This control provides +6dB boost - 20dB cut @ 1kHz with a bell response.

LF (Low Frequency or Bass) This control provides +6dB boost - 20dB cut @ 100Hz with a bell response. This response has been chosen so that sub sonic frequencies are not boosted by this control. All E.Q. controls have a centre detent at the (E.Q flat) centre position. The E.Q. function may be disabled by the setting of internal jumpers (see diagram).

AUX 2 Push button with led illumination. When depressed the signal in this module is mixed wi th any other source selected. The resulting mix is available at the Aux 2 outputs on the master module. Internal jumpers allow the source to be selected pre of post (before or after) the channel fader. (See output section for more options on Aux2)

AUX 1 has a similar function to Aux2. A control replaces the switch so a separate level mix of channels is available at the Aux1 outputs on the master module. Internal jumpers are also provided for pre post selection.

Bal Pan (Stereo balance & Pan) With a stereo source selected this control provides adjustment to balance stereo signals. With a microphone source selected or the mono switch depressed this control allows the source to be positioned anywhere in the stereo image. A centre detent is provided at the control centre position.

PFL (Pre Fade Listen) Push button with red led illumination. When depressed the signal in this module is connected to the PFL Mix Buss. Any number of channels may be selected simultaneously, the sum of which will be available in the master module for monitoring. An indicator led below the Vu meters also illuminate s if any PFL switch is depressed. (See monitoring section on output module for more information)

MONO Push button with red led illumination. When depressed this switch simply links left and right signals and allows stereo signals to operate in mono.

XFA (Crossfade A select) Push button with red led illumination. Depressing the switch routes the channel signal via the VCA controlled crossfader channel A. XFA will take priority if both buttons are depressed.

XFB (Crossfade B select) Push button with green led illumination. Depressing the switch routes the channel signal via the VCA controlled crossfader channel B. Red and green led switch illumination along with similar illumination on the crossfader gives g ood visual indication of routing status. If neither of the crossfade assign switches are depressed and a stereo source is selected the signal will be routed via the stereo buss to the output section bypassing the crossfade circuitry. If a microphone source is selected the crossfade A&B assign switches will not function and will not illuminate if depressed. The signal will be routed to the output section via the microphone mix buss. Fader A 60mm studio quality linear fader is provided. This should be used to fade up and down the volume of the channel. For normal production operation the fader should be set at the top (No.9) and the gain control adjusted for normal volume. The fader should be used to fade in the signal at the required time taking the fader to the top. This lets you concentrate on the timing confident that the volume will be correct. If you want to operate with some gain in hand (e.g. mic mixing) operate with the fader set a t No.7. Always operate with the gain set as low as possible to achieve the desired results. (See the section on gain)

MUTE Push button with red led illumination. When depressed signal feeds to the programme busses are muted. AUX1 and AUX2 are not af fected. An internal jumper allows this switch to be disabled. (Factory option - the mute switch may be rewired to provide a low voltage remote start switch wired to a 3.5mm jack socket on the rear panel.)

Internal Settings Jumper links are used to select and change functions. 1 - 5 uses 3 pin headers and the link should join the centre pin to one of the end pins. 6. Two pairs of pins - the link joins one pair of pins. The various link positions are also shown on the PCB. If you are changing link positions ensure they are seated correctly and all necessary links have been moved 1. 1 Jumper link. The position selects input B to microphone or stereo line input (in the microphone position the Xfade select switches are disabled.) 2. 2 Jumper links . The positions select input A to be a Magnetic phono cartridge equalised to RIAA or a normal flat response line input. Move both links. 3. 4 Jumper links . The positions select equalisation on or off (i.e. tone controls disabled). It is vital that all four jumpers are moved. 4. 2 pair of jumper links select Aux1 and Aux2 to be pre or post fader. (i.e. if the selected aux function is affected by the channel fader.) Move 2 links for AUX1 and 2 links for Aux2. E.G. an auxiliary set up for use as an echo send on a microphone channel would normally be set to post, so if the fader is closed no signal would be sent to the echo system. If the auxiliary function was in use as a foldback or monitoring feed it would normally be set to pre fader. Aux sends can be used for many tasks. 5. 1 Jumper link selects Phantom power on or off for microphone channels. 6. 1 Jumper link The position of this link determines if the channel mute button is enabled or disabled.
