Input

Pressing INPUT steps through each of the three inputs, as indicated by the corresponding LEDs. When the Mic LED is lit, the

microphone input is active etc. An XLR input for a microphone, as well as both XLR and TRS /” inputs for line-level sources,

can be found on the rear panel. A TS /” input for an instrument (DI) is available on the front panel.

Mic input gain

With the Mic input selected, the user has access to the full gain range in 0dB steps from 0dB to +60dB (yellow legend). The gain

range is split between two gain modes depending upon the status of the 0-60 switch.

Mode 1: Mic Gain Range 0-30

With the 0-60 switch off, the stepped gain dial operates over a gain range of 0dB to +0dB, the level of gain chosen being indicated

on the front panel by the outer arc of yellow numbers around the gain knob.

Mode 2: Mic Gain Range 30-60

With the 0-60 switch on (illuminated), the stepped gain dial operates over a gain range of 0dB to 60dB, the level of gain chosen

being indicated on the front panel by the outer arc of yellow numbers around the gain knob.

An additional 0dB of gain can be applied to the signal after the mic/line stepped Gain knob using the smooth rotation Trim knob.

(See the ‘Trim’ control text below for a full explanation.)

Line input gain

With the line input selected, the user has access to gain settings ranging from –0dB to +0dB, indicated on the front panel by the

arc of white numbers around the stepped gain knob. The 0-60 switch is inactive when the line input is selected, as the gain range

for line-level inputs is restricted to –0dB to +0dB in 0dB steps. An additional 0dB of gain can be applied to the signal after the

stepped mic/line gain knob using the smooth rotation Trim knob. (See the ‘Trim’ control text below for a full explanation.)

Instrument input gain

With the instrument input selected, gain is applied to the input signal by using the Instrument Gain dial, which allows +0dB to +0dB

of gain range. The level of gain chosen is indicated on the front panel by the arc of white numbers around the gain knob. This input

is suitable for high impedance sources such as guitar or bass pickups (which may be connected directly without the need for an

external DI box) or vintage synthesizers with high impedance outputs.

Trim

The Trim control provides additional variable gain of 0dB to +0dB when mic or line inputs are selected. The level of trim chosen is

indicated on the front panel by the arc of white numbers around the trim knob. The additional 0dB of gain that can be applied to the

mic or line signal is very useful for two reasons:

When high gain is required

Using trim in conjunction with the mic gain of 60dB gives a total of up to 80dB of pre-amp gain, making it very useful for getting good

digital recording levels from very low output dynamic and ribbon microphones.

Gain adjustment during recording

When small amounts of gain adjustment are needed to correct performance level variations during recording, use the trim knob

rather than the stepped mic/line gain knob, as switching the 0dB gain steps would be much too intrusive. It is therefore good

practice to apply some Trim gain before using the 0dB stepped gain knob to nd the optimum recording level so that the Trim

control can be used to gently add or take away gain later, if so required.

+48V

Pressing the +8V switch provides phantom power, suitable for condenser microphones, to the rear panel XLR microphone

connector. If you are unsure whether your microphone requires phantom power, refer to its handbook, as it is possible to damage

some microphones (most notably ribbon microphones) by providing phantom power.
