5. EQ->COMP - Press in to insert the EQ
before (pre) the compressor in the signal
path.
6. Press in TSP. This will engage the tubes
so that you are now in tube mode.
7. Press in SIDE CHAIN and SC LISTEN. You
are now monitoring the signal going through
the side chain. You can use the side chain
listen function as a parametric EQ on the
primary audio path.
8. Adjust the side chain parameters to the
following settings:
Both LF and HF side chain threshold fully
counter clockwise.
LF frequency set to 300 Hz.
HF frequency set to 1k6 Hz.
9. Press out the SC LISTEN switch (disengaged).
Now you have full compression, with fast
attack and slow release, and two different
frequencies going into the side chain that are
being compressed more than the overall
stereo signal.
Make yourself familiar with all of the functions
in the Vt-747sp. The combinations, colors,
and tones are endless. For more details on
each specific control or switch, please refer to
Chapter 4 - Operations and Controls.
3.0 Safety and Grounding
The following chapter describes how to
safely install your Vt-747sp for optimal sonic
performance.
3.1 Safety Instructions
This unit contains voltages that can cause
serious injury or death. Do not operate
with the covers removed.
Improper connection of the equipment-
grounding cable can result in a risk of electric
shock.
Check with a qualified electrician or
serviceman if you are in doubt about your
electrical power or ground connection. The
Vt-747sp is for use with an AC supply as
selected by the AC voltage selector (located
within the AC inlet on the rear of the chassis).
Voltages are 100-120-220-240 VAC +/-5%,
50-60Hz, at 60 watts.
3.2 Grounding Instructions
Always connect the Vt-747sp to a grounded
AC power circuit.
If the unit should malfunction or become
"live", the chassis ground will provide the path
of least resistance for electric current to
reduce the risk of fatal shock.
