4.6 EQUALISATION & FILTERS
Now the source can be metered as well as heard it is possible to experiment with
equalisation & filters. Select EQ (red LED) and try the effect of the filters first.
The low frequency (high pass) filter can be set 47Hz or 82Hz on 2 separate buttons & 120Hz
when both buttons are selected together. The high frequency (low pass) filter can be set
to 12KHz or 8.2KHz on 2 separate buttons and 4.7KHz when both buttons are selected
together.
The equalisation is in 4 bands. The HF band is shelving at 10KHz unless the button marked
5KHz is pressed. It may be set up or down to a maximum of 15dB. The LF band is shelving
at 60Hz unless the button marked 160Hz is pressed. It may also be set up or down to a
maximum of 15dB.
The two mid bands can also be set up or down to a maximum of 15dB around a frequency
set by a second knob in each band.
The bands cover HMF (High Mid Frequency) and LMF (Low Mid Frequency) ranges.
The Q of each band is about 1.0 unless the H1 Q button is pressed (a narrower mid-
band symbol) when it becomes approx 2.5.
4.7 AUXILIARIES
These may be set on the channel or group in use by simply pressing the ON button on
the Auxiliary to be used. In the case of Aux 5&6 or 7&8 which have common gain controls,
the buttons are marked 5, 6, 7&8.
The selection is normally POST fader and the led will usually light up green but it may
be set PRE fader by pressing the PRE button when the LED goes red.
The gain of the Auxiliary feed may be adjusted if required. Line-up is marked close to
3 o'clock. There is 5dB in hand above this.
Auxiliaries gain knobs are coloured as follows:-
1
2
3
4
5-6
7-8
These colours are repeated on the Auxiliary Master controls on the Main module panels.
Here are provided Master Gain controls with 10dB in hand above line-up (at 12 o'clock) &
bargraph level meters. Each output has a CUT button and the stereo outputs can be set
to MONO.
It is possible to monitor and meter (on the main meter) an Auxiliary by selecting it on the
LS1 MONITOR panel & following it on the meter by selecting LS SEL.
The CUT button does not cut the monitor & meter feeds.
