PM - 80R UNIVERSAL INPUT MODULE

Input Sources. The design of this module allows almost any input source to be

used. This is achieved by providing a balanced low impedance low noise

microphone pre-amplifier; a stereo RIAA equalised pre-amplifier (phono cartridge

input); a stereo balanced line level input stage and a stereo unbalanced line level

input stage.

Configuration - Internal jumper links fitted to pin headers select the input types

available. (Similar jumpers provide selection of other options.)

See later section on configuration Drg-1008.

Input Connectors - Rear panel mounted 2 - XLR input sockets, 2 - gold plated RCA

phono sockets, 1 - 1/4"- 3 pole jack socket (provides a connection to pick up the

microphone signal only, or connect external equipment into the microphone

channel).

Gain control allows the operator to compensate for variations in programme material

or signal level. (See later section on gain)

HF (High Frequency or Treble)

This control provides +10dB boost & -10dB cut @ 10KHz with a shelving response.

Mid (Middle Frequencies)

This control provides +10dB boost & -10dB @ 1KHz cut with a broad bell response.

LF (Low Frequency or Bass)

This control provides +10dB boost -10dB 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 later

section on configuration.

AUX - Aux send. A concealed push button with led illumination has been added.

When depressed the signal in this module is mixed with any other source selected.

The resulting mix is available at the Aux outputs on the master module. Internal

jumpers allow the source to be selected pre of post (before or after) the channel

fader.

Bal /Pan (Stereo balance & Pan)

With a stereo source selected this control provides adjustment to balance stereo

signals. With a microphone selected this control allows the source to be positioned

anywhere in the stereo image. A centre detent is provided at the control centre

position.

MON (Monitor sometimes called Cue or PFL Pre Fade Listen)

Push button with red led illumination.

When depressed the signal in this module is connected to the Monitor mix buss. Any number of

channels may be selected simultaneously, the sum of which will be monitored in the master module by

the meter and headphone amplifier.

MASTER fader - A 60mm studio quality linear fader is fitted 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 at No.7.

Always operate with the gain set as low as possible to achieve the desired results.

(See the later section on gain)
