A1 Monaural Amplifier
A1 Design
The A1 is a full range (20Hz - 20kHz) audio power amplifier. It provides RCA and XLR inputs for connection with all types
of receivers or separate audio components. The A1 is a single channel or monaural amplifier and can be used to drive any
loudspeaker with a minimum impedance of 3 ohm.
The A1 is a Class G design, which operates at lower temperatures than typical amplifier designs and is typically more effi-
cient. The A1 offers the wide dynamic range and low distortion typical of more conventional class AB designs.
A1 Placement
The A1 amplifier may be placed on a shelf, or in a standard 19" equipment rack using the optional rack ears and hardware.
See instructions on rack mounting below.
Ideally, the A1 should be placed in close proximity to the receiver or surround processor. Minimizing low level signal wire
lengths reduces the chance of noise pickup. If long runs (more than 20’) of signal cable are required we recommend using
the balanced (XLR) input on the amplifier.
Note: Due to the placement of the A1's power switch on the rear panel, do not install the A1 in a wooden box or similar enclo-
sure where access to the power switch is blocked or inconvenient.
Rack Mounting the A1 and or X1
You may need assistance to hold the A1 or X1 in place while mounting them in a rack.
Note: When rack mounting, we recommend you leave at least one rack space
between components (particularly amplifiers) for proper cooling.
Step One: Remove the two screws on each front side of the X1 or A1 with a #2
Phillips screwdriver.
Step Two: Position the rack ears over the threaded holes. Replace the two screws
and tighten both securely.
