MINX MIXER - OPERATING INSTRUCTIONS
- 5 -
Associated with the electret talkback microphone (5a), this centre biased momentary
toggle switch directs the output of the talkback mic. amp either to the control line
(CUE) when pushed to the left (i.e. towards PRES monitor select toggle) or to the
mixer output (O/P) when pushed to the right. Thus the engineer can talk to the
presenter, even during a live programme, by selecting CUE on presenter's
headphones and holding the PTT toggle to the left.
6.
Limiter
When selected, as indicated by orange iris, limits output at +8dBm (factory set).
Operation indicated by the led fitted into the PPM, attack and release program
controlled.
7.
Battery Check (Batt Test)
Push to read battery condition on the PPM. Replace/recharge batteries when level
reads lower than 5 on the PPM scale. Scale reads between 6 - 7 with new batteries.
8.
Peak Program Meter (PPM)
Scale 4=0dBu, 6=+8dBu. Movement and electronics to BS4297.
9.
Headphone Level (Cans)
A dual concentric pot. arrangement where the back (outer) knob adjusts presenter's (2
PRES) headphone level and the front (inner) knob adjusts engineer's (1ENG)
headphone level independently.
10.
Oscillator (OSC)
Directly left of the headphone level controls is the oscillator on/off toggle
switch.When switched downwards (ON) the oscillator generates a 1KHz tone at
0dBu which is routed to the mixer output. This can prove useful in patching-in the
Minx at a radio station when it is being used at a remote location or to ‘slate’ tape.
The oscillator is also essential for setting correct level line-ups.
NOTE:
The oscillator circuit employed uses a thermistor which will initially overshoot before
settling back to 0dBu. If following equipment is sensitive to overshoot, turn LIMITER on
before using oscillator.
