-10dBV ) or professional level (+4dbu). When the gain is too low, the tube effect

becomes less audible and the S/N (Signal to Noise) ratio deteriorates. Generally,

Dynamic mics and instruments without preamps will require more gain than con-

denser mics and instruments that have a built-in preamp. If you should require more

signal out of the preamp for a hotter recording level, cranking up the gain should

provide all the signal that you'll need.

To obtain the best possible S/N (Signal to Noise) ratio and subsequently the best

transparent sound, keep an eye on the 8 Digit Output Level Meter .

Drive (12 for CHANNEL 1 and 14for CHANNEL 2):

The effect achieved by this control can be subtle to extreme, depending on the

settings being used. A "warming up" of the sound can be noticed at lower settings.

This desirable effect is especially good for microphones and on an electric bass

and the resulting sound is infinitely richer and sweeter.

An over-driven signal can be achieved by significantly raising the level of the Drive

control. This over-driven tube effect is extremely useful in providing cool guitar

sounds and way cool for use with harmonicas for that authentic "Blues harp" vibe.

The limits on the possibilities of the Drive control are up to you, your application

and your imagination.
