ART Pro Audio Dual MP - Two Channel Tube Preamplifier - Manual (Page 5)

DOWN before “testing” the sound. When running one channel
into another (cascading) you have the potential for upwards to
120 to 140dB of gain.

The output control sets the output level of the Dual MP. When
the control is fully counterclockwise, there is no
output.Turning the control clockwise increases the level of the
output to a maximum of +10dB of gain. This gain is in addition
to the existing input gain.

A R T’s Dual MP circuitry is a hybrid design utilizing the latest
and most advanced solid state and tube technology. Using a
transformerless design throughout, the Dual MP maintains
exceptional signal integrity and extremely low noise. The Active
balanced input utilizes a hybrid multiple paired transistor
design providing extremely low noise and excellent CMRR. A
second stage 12AX7A tube running on a regulated DC voltage
of +50volts provides additional gain. The tube will overload
before the input or output stage. This allows the user to manip-
ulate the tube gain to meet their sonic requirements. The 1/4”
input has a high impedance preventing the loading of any
device connected to it, making the Dual MP perfect for DI appli-
cations.

Preamp
The main application of the Dual MP is a microphone preampli-
fier. Plug any microphone directly into either input and set the
input and output controls to provide a healthy level into the
next stage of your system.
DI
The Dual MP is ideal for use as a DI box. Plug the instrument
into either input and use the XLR or 1/4 (or both) outputs to
connect to your recorder, board or PA system.
2-mix
Because of its low noise and excellent tonal qualities, the Dual
MP is ideal for running mixes through before recording to DAT
or cassette. Used as a mastering device, the Dual MP is capable
of adding warmth and, set properly, gentle tube compression to
the incoming signal.
