PM-100 Master Module

The master module contains all the

electronics required for the various

summing amplifiers, output stages, VU

STEREO

JACK

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.

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

BOOTH

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

MON

BAL

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

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.
