The "PHASE"-switch inverts signal polarity and
is confirmed by the yellow "REV"- LED.
LOW CUT
In order to reduce undesired frequencies such
as wind or microphone handling noise, the
MIC-AMP F366 offers a Low-Cut Filter with a
corner frequeny of 70 Hz.
It is switchable into the signal path by the
"LOW-CUT"-Switch situated on the frontpanel.
Activ state is displayed by the "70 Hz"- LED.
LEVEL METER
Situated on the front panel above the switches
already mentioned, a four-segment LED bar-
graph displays the momentary output level.
The overall display range is 15 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 15 for details).
Ex works the red 0-dB LED is adjusted to +15
dB output level.
THE OUTPUTS
Each channel offers a balanced output with
gold plated XLR-type connectors. They are
situated on the rear of the unit and marked
"LINE OUT 1/2 (3/4, 5/6)".
The polarity meets AES 14-1992:
1 = Ground, 2 = (+) Phase, 3 = (-) Phase
The output impedance is approx. 30 ohms.
HINT:
In case of unbalanced termination of the
electronically balanced
outputs, pin 3 of the
XLR connector may not be shortened but must
be left open! Signal level is reduced by 6 dB!
OPTION
As an option MIC-AMP F366 may be equipped
with high quality output transformers. These
transformers are controlled by a special cir-
cuitry to achieve low inner resistance, very
good frequency range and low distortions.
They exceed IRT recommendations.
