1.2 MASTER SECTION OVERVIEW
The VTC Master Section is a triumph of intelligent, uncluttered design and contains:
•
Six Stereo Effects Returns on high quality Alps 60mm faders with control of Gain, AFL, and
Mute. Post fade individual routing paths to both headphone outputs are provided, complete
with an associated Level control for each headphone send.
•
A Headphone Matrix featuring two separate Phones outputs. Fed independently or in
combination from Control Room, Mix B, Aux 3/4, Aux 7/8 and External sources, this is a very
flexible and practical system with its own PFL.
•
Comprehensive Control Room section which allows the CR output to be fed from any
combination of L/R Mix, Mix B, 2TA, 2TB and Ext sources. It also features the easy-to-spot
Monitor Level control and a PFL trim control with +/-20dB of gain. Two Solo modes are
provided on the VTC: PFL or Solo In Place, with a switch in the CR section allowing Solo in
Place to be selected. A switch allows the Alternate Loudspeaker outputs to be monitored, and
the Control Room output can also be mono’d.
•
The Studio Output section – like the Control Room (CR) output – can be fed from the L/R
Mix, Mix B, 2TA, 2TB and Ext sources, along with a ‘Follow CR’ facility which allows the
Studio Output to automatically follow whatever source is feeding the CR output. The Studio
also has its own Level control along with Solo and On/Off switches.
•
The Oscillator is switchable between 1kHz or 10kHz and has its own Level control and On/
Off switch. The oscillator routes to both the groups and the L/R Mix.
•
The Talkback section can be fed to any combination of Tape (groups and L/R Mix), Studio
output and Phones 1&2. It has its own ‘Talk’ switch which can be internally set for non-
latching (the default) or latching operation, and activating this switch automatically dims the
Control Room output by 12dB.
•
Master control of Mix B. The Mix B signals always feed the separate Mix B stereo output, but
an assign switch also allows routing of these signals to the main L/R Mix, along with an
associated level control.
•
Group Section. Eight 100mm Alps group faders, each of which can be solo’d, fed to group
and tape outputs, or routed to the L/R mix, allowing both track laying and conventional sub
grouping on mixdown. When fed to the L/R mix, each group can be routed in mono equally to
both left and right busses , or routed in pairs hard left or right.
•
Master Fader (again a 100mm Alps type) allows control of the L/R Mix level, and like the
channel and Mix B faders is fitted with Stat and Auto switches for use with third party
automation systems.
