LOW CUT
In order to reduce undesired frequencies such as wind or microphone
handling noise, the MPA RS 01 offers a Low-Cut Filter with a corner
frequency of 70 Hz.
It is inserted into the signal path by the "LOW-CUT"-Switch situated on
the front panel. Active state is displayed by the "70 Hz"- LED.
LEVEL METER
Situated on the front panel between the gain switches, a seven-segment
LED bar-graph displays the momentary output level. The overall display
range is 36 dB.
The dynamic characteristics are according to DIN specifications, with a
rise time of <10 milliseconds and 1.5 seconds release time for a 20 dB
level change.
The display's sensitivity can be adjusted on the main PCB to meet user-
specific requirements (see page 17 for details).
Ex works the red 0 dBr LED is adjusted to a level of +15 dBu.
Please note that MPA RS 01 is able to output a level of over +20 dBu,
thus a headroom of 5 dB remains.
