Owner's Manual
GENERAL DESCRIPTION
The Professional Master Blender from Raven Labs provides the
professional musician the ultimate device in blending together two
separate signal sources. It can be used with an acoustic guitar or
bass having a piezo pickup and soundhole microphone, a stereo
instrument, two separate instruments or keyboards, or instrument,
drum machine, tape deck, etc. Of course, it also makes a great
preamp for any single instrument.
Great care has been taken in the selection of components and
impedances to insure crystal clarity, wide frequency response, low
noise and minimum distortion. As well, it is packed with useful
features. The PMB-II can be powered with two nine-volt batteries, or
a wall mounted A/C adapter (sold separately).

INPUT JACKS
Three individual input jacks labeled INST (Instrument), STEREO, and
AUX/MIC (Auxiliary/Microphone) are provided. Each input is
equipped with an RF trap to help eliminate radio station
interference.
The INSTRUMENT input is ideal for piezo pickups and all devices
needing a high input impedance. The input impedance is 10 Meg
ohms. If you are not blending two signals, we recommend using this
input regardless of the type of pickup. The AUXILIARY/MICROPHONE
input has an input impedance of 820K Ohms, and is suited for
microphones, magnetic pickups, keyboards, drum machines, etc. It
also has "phantom power" if needed. The STEREO input jack can
receive a dual signal, such as a pickup and soundhole microphone.
The TIP of the stereo jack is sent to the Instrument channel. The
RING is goes to the Aux/Mic channel. When the Stereo input is used,
