TUBE COMPOSER T1952

Fig. 1.3: Control elements of the peak limiter and tube sections

The VU METER can display three levels: the actual gain reduction of the compressor, the input or the

output level. Gain reduction is displayed in a range of 1 to 30 dB, the input or output level is displayed in

a range of -30 to +10 dB. The nominal level the display is switchable between -10 dBV or +4 dBu with

the OPERATING LEVEL switch.

With the GAIN RED/LEVEL switch the above described VU meters can be switched between LEVEL or

GAIN REDUCTION mode.

If switch

is set to LEVEL, you can switch further between input and output level.

The peak limiter limits the signal to a level adjusted with the THRESHOLD control. Owing to its

extremely fast response (Zero attack), the limiter is capable of limiting signal peaks without audible

distortion. Whenever the signal is limited for more than 20 ms, the overall level is reduced for about 1

second to avoid heavy and thus audible signal distortion.

When you use the peak limiter as a protective device against signal peaks, the THRESHOLD

control should be set in combination with the OUTPUT control in the compressor section so

that the peak limiter responds rarely or not at all. Thus, only real signal peaks will activate the

limiter circuit. However, to produce creative sound effects, the peak limiter can be

deliberately set to lower levels.

The LIM LED lights up as soon as the limiter function is activated.

The WARMTH control determines the amount of harmonics the UTC circuit adds to the signal. This is

the amount of tube sound (WARMTH) that is added.

The WARMTH meter displays the amount of added harmonics. Thus, the amount of harmonics, or tube

sound (WARMTH), the UTC circuit adds to the signal is set.

Use the POWER switch to turn the TUBE COMPOSER on or off. When switched of the

TUBE COMPOSER automatically switches to a hard-bypass mode, the signal is then led directly to

the outputs.
