HI-PASS FILTER

 

 

A variable frequency filter is provided covering a range of

 

20Hz to 200Hz., and this is always in circuit. This may be

 

found useful to reduce the level of stage-driven low frequency

 

feedback, or particularly to tailor the output frequency to

 

match more closely the frequency range of smaller wedge

 

monitor speakers which may not be able to tolerate high lev-

 

els of LF signal. Rotate the control fully anticlockwise when

 

the filter is not required.

 

 

5.

TALKBACK

 

 

Pressing the TALKBACK switch routes the engineer’s talk-

 

back microphone signal to the monitor output, at the level set

 

on the T/B gain control on the Master section, and inde-

 

pendent of the output fader level. At the same time the local

 

monitor mix is dimmed by approximately 6dB to allow the

 

engineer’s voice to be heard over the mix, and the Wedge out-

 

put also dims to prevent feedback through the talkback mic.

 

Note that Talkback is disabled when DIM is pressed.

 

 

6.

DIM

 

 

Pressing the large DIM switch attenuates the monitor output

 

by 6dB as an immediate way of eliminating feedback while

 

the source of the problem is identified.

 

 

7.

PFL

 

 

When the PFL switch is pressed, the Pre-Fade signal is fed to

 

the headphones, replacing the normal submix signal. The

 

PFL ACTIVE LED on the master section illuminates to warn

 

that the wedge/phones outputs and the meter are now re-

 

sponding to the PFL selection and the PFL LED on the input

 

channel lights to identify the active channel. This is a useful

 

way of listening to any required signal so that adjustments

 

can be made or problems traced.

 

 

8.

BARGRAPH METER

 

 

A sixteen segment, three colour bargraph meter monitors the

output signal. The meter has a peak response, and since it reads the final output signal it will also be affected by the DIM switch and include any talkback signal. The bargraph may be calibrated by a trimmer accessed via a hole in the panel above the meter. Adjustments may be made using a
