6.3 Microphone Level Controls
Each microphone has separate front panel
mounted controls for their respective level.
Rotating any microphone level control fully
anti-clockwise effectively turns the
microphone off. In addition microphones can
be muted via the access contacts on the rear
panel (see section 6.1)
Master microphone level can be controlled
locally via the front panel rotary control, or
through a remote wall plate up to 100m away
from the unit. To configure the CX462 for
remote level operation, the front panel switch
must be in the 'REMOTE' position.
The rear panel switch marked 'REMOTE
TYPE' should be in the 'ANALOGUE' position.
Master microphone level can also be
controlled via the Cloud CDI-S100 Serial
Interface Module (see section 8.2).
6.4 Microphone Equalisation
Two-band equalisation is provided for each individual microphone input. The pre-set controls
to adjust the equalisation are located to the upper-right of each front panel microphone level
control. The characteristics of the equalisation are optimised for the tonal correction of
speech signals. The HF control provides ±10dB at 5kHz whilst the LF control provides ±10dB
at 150Hz.
A parametric equaliser is applied to all the microphone signals, to allow the installer to correct
for microphone or room resonance. The pre-set controls to adjust the equalisation are
located to the upper-right of the microphone master level control (front panel). This equaliser
has been optimised for vocals and provides a gain of ±10dB over a frequency range of
300Hz - 3kHz.
All microphone equalisation controls are concealed behind the removable front panel. To
effectively bypass an equalisation section, the gain control should be set to 0dB (mid-
position/vertical).
6.5 High Pass Filter
All microphone channels pass through a high pass filter operating at 150Hz with a slope of
18dB per octave; as such it provides effective attenuation of breath blasts and LF handling
noises. This filter can be switched in or out via the front-panel switch located to the right of
the microphone master level control. This switch will be concealed when the removable front
panel is in place.
