The following are answers to Frequently
Asked Questions about the Vt-737sp:
Q: Can I use the Vt-737sp as an insert for
compression and EQ?
A: Yes. The Vt-737sp is perfect as an insert of a
recorded signal such as vocals, guitars, key-
boards, acoustic piano, drums, etc. Many engi-
neers use their Vt-737sp on their most import-
ant track during mixdown.
Q: How often will I need to change the
tubes?
A: The vacuum tubes on the Vt-737sp are mili-
tary spec tubes rated for over 5,000 hours.
Avalon recommends
approximately every 2 years or so on a unit that
is used regularly. Avalon recommends that you
replace tubes with exact make and model of the
tubes that Avalon specifies. You may purchase
a spare set of tubes for your Vt-737sp directly
from Avalon.
Q: What is the difference between the
Vt-737sp and the Vt-747sp?
A: The Vt-737sp is a mono Mic, Line, and
Instrument level preamplifier with compressor
and parametric equalizer. It is great for record-
ing one channel at a time and for mixdown on
the most important channel.
The Vt-737sp is a dedicated stereo line level
compressor and graphic equalizer. It has no
microphone preamplifier. The Vt-747sp is great
for stereo keyboards,
machines, stereo submix or mix buss applica-
tions and mastering.
