The AMP-1A Series of audio monitors provides self-powered, full-fidelity stereo monitoring in the smallest rack space possible. All
models in the AMP1A Series contain five high performance transducers driven by three power amplifiers: two amplifier/driver
combinations handle midrange and high frequency information in stereo, while the third center channel reproduces information
below the 500 Hz crossover point.
All AMP-1A models come equipped with a ganged stereo volume control and balance pot, power indication LED, and headphone
output. Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement
immediately adjacent to video monitors with no color impurities.
The AMP1A-4S model features four pairs (8 channels) of balanced inputs on Phoenix connectors and the AMP1A-10S features ten
pairs (20 channels) of these inputs. Any pair of inputs is selectable for monitoring via a rotary source select switch on the front
panel. An additional pair of XLR connectors output the selected audio signals for connecting to downstream equipment.
The AMP1A-LP4S and AMP1A-LP10S models offer the same input features as the -4S and -10S models with the addition of dual 10-
segment tri-color LED bargraph level meters and Wohlers' proprietary three-LED stereo phase indication feature.
• 98 dB SPL at two feet
• Only one rack space high
• Excellent high frequency response for positive detection
of background whine and noise
• Audible indication of phase/polarity problems
• Thorough magnetic shielding for placement next to video
monitors
