Extron just introduced the XPA U 758, an eight-channel half-rack amplifier; each channel has 75 watts of power. This means the XPA U 758 lets you install sixteen 75-watt channels in a single rack space without the need for ventilation (with two side-by-side units).
The XPA Ultra lineup of UL 2043 plenum-rated amplifiers includes single and side-by-side rack-mount hardware and a newly designed rear panel that makes installing the optional Flexible Conduit Adapter Kit easy. Recessed, detented level controls with laser-etched markings provide enhanced visibility and repeatability of settings.
Specs on the XPA U 758 are here.
