M-Audio Audio Buddy User Manual
Features
The Audio Buddy features include:
• 2 independent XLR, fully balanced inputs.
• 2 alternate, independent 1/4” unbalanced, high impedance inputs.
These alternate 1/4” inputs are impedance matched for ideal
performance with typical electric guitars.
• Separate gain controls for each of the two preamplifiers.
• Individual signal and clipping LEDs for each of the preamplifiers.
• XLR phantom power can be switched on and off for both of the mic preamps.
• Phantom power on or off LED indicator.
• Dual purpose independent 1/4” outputs which accept either
tip-ring-sleeve plugs for balanced signal or tip-sleeve plug for
unbalanced signal.
• Super-small size: 5.5" x 3.3" x 1.7".
• Very-quiet S/N specification.
• Heavy-duty all metal construction.
Specifications
• Frequency Response: 5 Hz to 50 kHz, +0, -3 dB.
• Mic Gain: 60 dB max.
• Mic Input Impedance: 1 K ohm.
• Guitar Gain: 40 dB max.
• Guitar Input Impedance: 100 K ohms.
• Approximate weight: under 1/2 lb.
• Power supply: 9 VAC; 500 milliamps.
Introduction
This product complies with European CE requirements.
Thank you for your purchase of the M-Audio
AudioBuddy™, mic preamp and direct box. M-Audio has
designed and manufactured several different audio mixers
including MiniMixer, MicroMixer 18, MultiMixer 6,
MultiMixer 10 and miXim 10. All of these mixers have two
things in common: 1.) they are exceedingly quiet -- quieter
than 99% of all mixers on the market and 2.) they are
uniquely configured to meet the specific needs of the MIDI
and multimedia musician.
The Audio Buddy, once again, fits these two criteria. First,
it is a very quiet mic preamp. This is because the unit’s
simple and efficient design and ultra compact layout
eliminates much of the noise. The unit also has a higher
than usual voltage “rail” across its internal op-amps. This
means that you get more “punch” and much more dynamic
audio output.
Secondly, the Audio Buddy (when coupled with its ultra quiet
performance) is the perfect audio “gateway” for recording the
two most significant, non-line level instruments in the studio:
microphones and electric guitars.
Users Manual
The Audio Buddy has two completely independent
preamplifier sections. Each of these sections has: 1.) a
balanced XLR input on the back of the unit, 2.) a high
impedance 1/4” unbalanced input (TS) on the front of the
unit, 3.) signal (present) and clipping LEDs, 4.) a gain
control and 5.) a 1/4” dual purpose output on the back of
the unit that provides either an unbalanced out (when a
mono plug is used) or a balanced out (when a stereo plug
is used).
IMPORTANT
:
Whenever one of the front panel high
impedance inputs is used, the associated back panel XLR
is disabled.
The Audio Buddy also has built in phantom power which
can be switched on or off for both channels. When the rear
panel phantom power switch is in, phantom power to both
channels is turned on and the front Phan(tom) power LED
will light.
IMPORTANT
:
Since the phantom power switch turns
phantom power on or off for both channels, there is no way
to turn phantom power on for one channel and off for the
other channel. If you are using the high impedance inputs
the phantom power switch has no effect.
