Here's a used amplified speaker panel, commonly used for confidence monitoring of audio lines. Note that no power supply is included (unit accepts 24V AC via the barrel connector on the rear). No Phoenix connector blocks are included but they are available from most of the parts houses - for example here. This unit takes 8 3-position blocks.
The AMP1A stereo audio monitor provides self-powered, full-fidelity stereo monitoring of of analog audio in the smallest rack space possible (1U) with four inputs (ie. two stereo sources) on 5mm Phoenix blocks on the rear panel.
The audio amplifier section features five high performance transducers driven by three power amplifiers: two amplifier/driver combinations handle midrange and high frequency information in stereo (left and right speakers), while the third center channel reproduces information below the 500 Hz crossover point (woofer speaker).
Output limiter circuits are incorporated to protect the speakers, and extensive magnetic shielding allows placement immediately adjacent to magnetically sensitive equipment, such as video monitors.
The unit also features a two input selectors (left/right), volume control, balance pot, headphone jack, and power indication LED.
If you need the matching connector blocks then these are standard 5mm Phoenix/Euroblock types - for example these.
No power supply is included.
