QUICKSET UP 

 

The MlCROCAB II Miked Guitar Cabinet Emulator is designed to accept preamp/effects 
and poweramp output levels. DO NOT UNPLUG YOUR TUBE POWER AMPLIFIER 
OUTPUTS from your speakers or load box when using the MlCROCAB II ! 
 

1.  Connect stereo inputs (A & B) on rear panel of 

MlCROCAB II 

to (he outputs of your 

preamp or effects device using shielded 1/4" phone cables. Or connect 1/4" 
unshielded phone speaker cables to your power amplifier output(s). 

2.  Use your choice of the 

MlCROCAB II's 

1/4" or XLR (balanced) outputs to connect 

the 

MlCROCAB II 

to the inputs of your recording or sound reinforcement mixing 

console. For stereo operation, connect outputs A & B to separate inputs on your 
mixing console. 

3.  Use ground lift switch if necessary to eliminate any line noise or hum that may be 

present from poorly-balanced power sources or ground loops in your system. 

 
NOTE: YOU MUST HAVE A GOOD TONE FIRST! SET YOUR PREAMP AND EFFECTS 
TO GET YOUR BEST TONE USING YOUR WHOLE RIG, INCLUDING THE GUITAR 
CABINETS, 

BEFORE 

PATCHING IN THE MlCROCAB II.

 

 

USING THE MICROCAB II

 

The MlCROCAB II can be used in the recording studio to quickly capture "that right tone" just 
as it sounds coming out of your guitar cabinets. The MlCROCAB II is also used for live sound 
reinforcement to get the exact tone on stage into the house system, without much of the 
hassle involved in lengthy sound checks and mike placement trial and error, while providing 
absolute isolation from other instruments on-stage. 
Since guitar speaker cabinet systems don't have a flat frequency response, some outboard 
EQ is essential to simulate the characteristic tone and presence of a "live" speaker cabinet.  
 
The ADA MlCROCAB II is designed to emulate the presence, tone and coloration found in a 
variety of modern and vintage speaker cabinets. Further, since the signal at the speaker 
cabinet is normally brought to your mixing console via a microphone, and not through a direct 
box (this would sound terrible), the microphone's frequency response must be taken into 
account. The MlCROCAB II emulates this characteristic, delivering the "feel" and tone that 
has become an integral part of the sound of amplified guitar. 
 
Additionally, the ADA MlCROCAB II is capable of emulating the close-miking characteristics 
of the Shure SM57 microphone—the industry standard for guitar miking in the studio and live 
sound reinforcement. The SM57 is well-noted for its "proximity effect," or low frequency boost 
at 180 Hz when placed very near the sound source (see Huber, 

Microphone Manual, 

Focal 

Press, 1988, p. 258), further enhancing the "thump" effect of the British-style 4x12 cabinet. 
Also note, on the next page, that the high frequency response from the Shure SM57 when 
placed off-axis is greatly attenuated. The shallow comb filter nodes across the mid-frequency 
band, shown on page 8, is another "live miking" characteristic emulated by the MlCROCABII.
