DUAL PATH MONO MODULE
DESCRIPTION

3.0 DUAL PATH MONO MODULE - DESCRIPTION

Cinemix's Dual Path mono input module is a basic input / output design whereby
all signal flow takes place from the microphone to the multitrack. Each dual
path mono module is shipped with PowerVCA Automation and a 13 segment
LED bargraph meter. The mic/line inputs are in the CHANNEL section of the
module while the TAPE machine outputs are in the MIX section.
The following sections explain the many functions and features of
each section of the dual path input module.

3.1 CHANNEL SECTION

The input section controls all incoming signals from microphone, line,
and multitrack outputs. A 48V phantom power switch for condenser
microphones or direct boxes can be silently switched in or out of the
circuit. The Line switch converts the Channel input from a balanced
mic input into a balanced line input. Cinemix has separate electronics
for each input. The top knob of the dual concentric GAIN control
adjusts the mic/line levels in the CHANnel path and the bottom
control adjusts the (tape) input of the MIX path.
When the GAIN control is accurately set, it is possible to achieve the
very best signal to noise ratio and maximum headroom Cinemix was
designed to achieve.
3.2 EQUALIZER SECTION - CHANNEL PATH
This four-band parametric equalizer is unique in its design. There are
four bands, the high and low bands are sweepable frequency, shelving
characteris- tics type with a boost or cut of 16 dB. The two mid
bands each sweepable frequency peak/dip type with a boost or cut of
16 dB.
The HF (high frequency) section is a variable frequency shelving
type, sweepable from 4,000 Hz to 20,000 Hz with a max. boost or
cut of 16 dB.
The HMF (High / Mid Freq.) section has level and frequency controls
with variable frequency ranges from 600 Hz to 15,000 Hz and has a
maximum boost or cut of 16 dB. The bandwidth has a Q factor of
1.5.
The LMF (Low / Mid Freq.) section has level and frequency controls
with variable ranges from 40 Hz to 1000 Hz and has a max boost or
cut of 16 dB. The bandwidth has a Q factor of 1.5.
The LF (low frequency) section is a variable frequency shelving type,
sweepable from 10 Hz to 500 Hz with a maximum boost or cut of
16 dB.
