1962 OPERATORS’ MANUAL

CONTROL DESCRIPTION

The 1962 comprises two independent audio channels plus a Stereo Mix section, and both

channels may be operated independently or linked for stereo operation. When used in linked

mode, the control-circuitry for both channels responds to the average of the two channel

settings. It helps to avoid confusion if both sets of channel controls have similar, or, as near

as possible, the same settings. Digital output capability is only available if a D62 digital

interface has been fitted.

CHANNEL INPUT

Source Select:

This four-position rotary switch selects the audio input source, which can be

Mic, Mic with 48V phantom power, Line or Aux. The Line and Mic inputs are

via rear-panel XLRs while the Aux input jack is located on the front panel. A

red LED shows when the phantom powered mic option has been selected.

Limit

: The limiter is available for all input selections and, when enabled, will prevent

clipping in situations where the maximum input level cannot be determined

with accuracy. Use of the limiter also makes it possible to run the output

closer the digital peak level (0dB) without the risk of clipping. Note that with

Line input selected the Limit headroom is only 10dB. Large amounts of gain

could exceed this, resulting in distortion.

A status LED indicates that the limit function is active, and if the signal level

is increased to a point where the limiter operates, the GR (Gain Reduction)

LED will illuminate. It is usually acceptable for the GR LED to flash on

occasional signal peaks, but if it lights regularly or almost continuously, it is

invariably best to reduce the input level using the input gain control, and/or

adjusting the EQ and Tube Drive settings.

For stereo operation, the limiters should either both be active, or, both

bypassed, to prevent an unwanted image shift(s) during limiting.

As with all limiters, excessive amounts of limiting will be audible, but used

carefully, the limiter offers protection against transient clipping while retaining

tonal transparency.
