SIGNAL GOING TO THE RECORDER (IN),
Because of its specially designed signal path, the VTB-1 can be used to both feed and
monitor a recorded track using its Insert Jack. The insert point is after the HPF, but
directly before the Blend Control. The signal feed from the insert jack is before any tube
circuitry, so the recorded signal will always be a SS only signal. The Playback output
from the Recorder uses the return path of the insert jack which directly feeds the Tube
Blend control and then the Output Level pot. By using the Blend control, the user can
add the desired amount of Tube Sound at the final mix stage instead of when tracking.
This allows for more variety during mixdown and contributes to less finger-pointing when
it's decided that the sound you originally recorded is not really what you want now.

NOTE: The VTB-1 meter is calibrated
for Pro level operation (+4dBu). The
meter may stay in its lower ranges when
driving semi-pro gear (-10dBV levels).
If your equipment has a level-select
switch, set it for +4 operation for best
results and quietest operation.
