3. CHANNEL MODULE
3.1 Channel Input Stage
PHANTOM POWER (1)
Individual +48V phantom power switching is available on each channel.
This meets the power needs of condenser microphones and DI boxes
when required. To prevent clicks or thumps it is advisable to ensure that
the system gain is set to minimum when switching phantom power on,
or connecting a microphone when phantom power is applied.
MIC/LINE SWITCH (2)
Mic/Line preamp input switch. This selects which source signal is fed
through to the console preamp stage.
Valve Stage
The microphone pre amp stage is one of the key weaknesses on many
consoles but on the VTC it is one of its great strengths. Combining an
SSM 2017 solid state stage with an ECC83/12AX7A secondary valve
stage gives the VTC mic pre amp the ideal combination of low noise
performance (-127dBu) and rich valve warmth. The valve stage is ‘post’
the Gain, LF Cut, Phase and Flip switches, and ‘pre’ the channel insert
point.
PHASE REVERSE (3)
The Phase Reverse button operates on both the mic and line inputs, and
is designed principally to correct phase cancellation caused by multiple
