OPERATION.

Front Panel.

The front panel controls are identified in fig.3

Input Stage.

Ensure that the correct input connector, mic or line, is being used and that the front

panel switch is set to the appropriate position. Note that both mic and line inputs may

be connected at the same time, but only one is selected.

+48V phantom power is available at the mic socket, selected by a front switch and

signalled by a red LED. Phantom power should only be used in conjunction with

suitable microphones.

CAUTION: Operation of the phantom power switch, or plugging a microphone in

with phantom power applied, may cause a click or thump in your loudspeakers. To

prevent this happening, ensure that the system gain is set to minimum (e.g. on your

mixing console fader or power amplifier), before operating the switch or plugging in a

microphone.

If the gain required is not known, set the control to minimum with the EQ by-passed,

and gradually increase the gain until the required output level is achieved. Unity gain

(0dB) is obtained from the line input at the centre-detent of the gain control.

Auxiliary Input.

The front panel auxiliary input socket accepts signals from guitar, keyboard, and high

impedance pickups or microphones. Plugging a jack plug into the auxiliary socket

automatically disconnects the channel mic or line inputs, and replaces them with the

aux input.

The sensitivity of the Aux input is controlled by the mic/line switch. In the line

position, low gain is selected, suitable for most keyboards or active guitars, whilst in

the mic position, the gain is increased to match passive guitars and hi-z microphones

or pickups. The input gain control also remains operative when using the Aux input.

HF and LF Cut Filters.

Both channels are equipped with high pass (also known as LF cut) and low pass (or

HF cut) filters, with a slope of 12dB per octave. Each filter has a continuously

variable frequency control and on/off switch with yellow LED.
