Key Filter

In normal operation, the filter only affects the way the MX40

responds to the incoming programme material - it does not have

any direct effect on the output signal, but when Key listen is

enabled, the effect of the key filter on the programme material is

heard at the output. These switches are independent of any

linking and enable Key Listen of only their respective channel.

50Hz to 8KHz with a width (or 'Q') of one octave.

Use Key Filter to hear the filter, and tune into the loudest part of

the trigger source sound.

When in the Ext(ernal) Key position, the LED will be illuminated

and the common external key source buss is used to control the

gate action, making it possible to gate one sound according to the

signal dynamics of another, independent signal. If released, this

switch causes the gate to respond to the dynamics of the signal

present at the channel signal input socket.

If no Ext Key input is plugged into the unit, then Channel 1's

audio signal becomes the default trigger source available to all

channels selected by the Key Input.

This switch is used to enable the control of the key trigger filter. It

is normal that this switch would be selected except where the

internal (or external) control signal has a broad spectrum of audio

information that the narrow pass-band of the filter would

otherwise restrict trigger information.

Linking

The Link buttons are located between odd/even channels, and

when depressed, cause the channel on the right (channel 2 or 4)

to be controlled by the left-hand channel (channel 1 or 3). In

linked mode, the red status LED beneath the Slave Link switch

will be illuminated, and the Ext Key and Peak Punch LEDs of the

slave channel will be extinguished. This indicates which controls

of the slave channel are still operative.
