Telex DOC02-DN9848 specifications Output Gain and Mute - Front Panel Control, Output Channels

Output Channels

1The meter uses a downward relative scale where the 0 segment represents the limiter threshold. For example, if the limiter threshold is set to +5dB in the output menu page, then the signal meter 0 segment represents 5dBu true value, the –3 segment becomes 2dBu down, - 6 becomes -1dBu down and so on.

The compressor threshold is also marked, relative to the limiter threshold, by a single steadily lit segment. For example, when the limiter threshold is set to 8dBu, the 0 segment is 8dBu; if the compressor threshold is –1dBu, segment 9 will be lit.

Note

If the limiter is set to OFF, the meter is scaled relative to 21dBu.

2While the signal level lies below the compressor threshold, the meter lights upwards from -40 such that the current headroom to both the compressor and limiter thresholds can be monitored.

3When the signal level reaches the compressor threshold level, the meter ‘flips’ and reads downwards to show the amount of gain reduction applied to the signal.

4With further increase, the meter reads in both directions: i.e., it increments upwards to track the signal level as it approaches the limiter threshold and increments downwards to show the applied gain reduction.

5When the limiter kicks in, the meter flips to read downwards from the 0 segment instead of just from the compressor threshold. It now shows the summed gain reduction from both compressor and limiter.

6.4. Output Gain and Mute - Front Panel Control

Each output is equipped with a dual action rotary/push-switch control for adjusting or muting the output level. Note that zero mark on the control refers to the baseline output level set in the Output menu (see Section 6.2.4) and hence the rotary control provides fine-tuning referred to this level.

To increase/decrease the level	turn clockwise/anti-clockwise
To mute an output	push in and hold until the red ring lights
To un-mute an output	push in and hold until the red ring light goes out.
To mute all outputs	push in and hold an unlit output until it and then all
	other controls light
To un-mute all outputs	push in and hold a muted (lit) output until it and then
	all other red rings go out
