Avalon VT-737SP, Руководство по эксплуатации

Страница: 41 / 58

Q: Can I damage the Vt-737sp by turning
the preamp gain up too high?
A: No. The Vt-737sp has enourmous head-
room (+36dB on Line Input). Crank it up and
check it out.
Q: Why does Avalon use opto-compres-
sors?
A: Avalon uses opto-compressors because
they are the most musical of all compressor
types.
Q: Can I do mastering with a pair of
Vt-737sp’s?
A: Yes. The Link jack in the back enables you
to link the compressors of two Vt-7337sp’s.
You will have to adjust the EQ controls sepa-
rately on each unit. The noise floor is low
enough for mastering and EQ is definitely
sweet enough. Avalon recommends either the
AD2044 compressor and AD2077 (or AD2055)
equalizer for professional mastering. Also the
Vt-747sp is wonderful for project studio mas-
tering since it is a dedicated stereo unit.
Q: Is the Vt-737sp durable enough for the
road?
A: Yes. The Vt-737sp as well as all Avalon
equipment is literally “built like a tank”. Steel
chassis, metal faceplate, metal knobs, all
circuit boards are screwed to chassis, etc.
Q: Should I power down the Vt-737sp?
A: The Vt-737sp is equipped with a “soft-start”
procedure that slowly brings the unit to life
without damaging the tubes. Avalon recom-
mends that you turn the unit off if not being
used for more than 4 hours. This procedure
will also save on your electric bills.
Q: Will the Vt-737sp continue to work when
I travel to different countries?
A: Yes. The power supply on the Vt-737sp has
selectable voltages: 100V, 120V, 220V, and
240V. It is very easy to change the voltage.
See Chapter 3 (page 13).
Q: Why does the needle in the VU meter
drift to the left of 0dB after the Vt-737sp
warms up?
A: As the unit warms up, after approximately
30 minutes, the resistance of the meter coil is
increased with heat and the needle then
settles into its opening 0dB position (just like
the old LA2A’s). To calibrate the VU meter to
0dB see page 44.
Q: Will the Vt-737sp work with my unbal-
anced inputs on my recording device?
A: Yes. You need to make sure that the cables
you are using are wired the same (pin 2 hot).
You can get a cable that has XLR on one side
and RCA or 1/4” on the other. This will work
fine for the unbalanced system, as long as the
cables are not over 10ft in length.
Q: Will the Vt-737sp work if it is going into a
recording device that is designed for -10dB
operation?
A: Yes. The Vt-737sp will work however the
signal coming from the Vt-737sp may be too
hot of a signal and you may need to turn down
the output control so that the signal more
closely matches the -10dB machine. If you
have a choice, you should always run at +4dB.
Q: Can I try using different types of tubes in
the Vt-737sp to get different or better
sounds?
A: Avalon has selected the tubes in your
Vt-737sp for optimal sonic performance.
