5.6 Output Gain.

This controls the level at the equipment outputs, and is variable between -∞ and +15dB.

This control acts like an output fader effectively, and is very useful when recording direct

to tape or hard disc through the equipment. You may find that some digital recorders

require a good deal of input level in order to register a 0dB reading on their meters. This is

normal, since many digital recorders are designed to preserve headroom and keep the

signal well below the 0dB clip point - thus preventing the recorder distorting. The

equipment provides ample gain to drive digital recorders, but you may find the Output

Gain control has to be set to higher levels because of it.

The equipment is equipped with an illuminated VU meter. The Meter switch enables the

equipment's VU meter to monitor one of two parameters. The normal mode allows the

meter to read the audio output level, and is calibrated to read 0VU when a +4dBu signal is

produced at the balanced line outputs of the equipment. Your dealer if required may adjust

the reference point internally.

Increasing the Output Level control on the equipment towards the +15dB setting will

cause the equipment's meter to move further towards the red area and possibly to the end

of the scale if sufficient gain is applied.

Sometimes the output level of the equipment may need to be set to a relatively high

level, particularly when driving a digital recorder. The Meter '+10dB' setting reduces the

normal meter reading by 10dB so that high output levels can be generated without the VU

needle pressing constantly at its end stop. This doesn't affect the actual output level, but

only the metered reading. This setting also has no effect when the G/R switch is engaged

and the meter is reading the amount of gain reduction.
