This model puts eight of them in a frame half a rack wide and one unit high, and it cools by convection with no vents and no fan, so it can sit flush against neighboring gear or inside a closed credenza. Extron rates the enclosure for plenum airspaces, which widens where an installer is permitted to put it.\u003c\/p\u003e\n\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEight channels rated 75 W into 8 ohms, or 50 W into 4 ohms, each measured at 1 kHz and 0.1% THD.\u003c\/li\u003e\n\u003cli\u003eConvection cooling with no vents — silent operation, and no airflow clearance to budget for.\u003c\/li\u003e\n\u003cli\u003eFrequency response held to 20 Hz - 20 kHz within ±1 dB, with 100 dB unweighted S\/N and a damping factor above 100 at 8 ohms.\u003c\/li\u003e\n\u003cli\u003eEight balanced or unbalanced inputs across four 5-pole 3.5 mm captive screw connectors, +4 dBu nominal and +20 dBu maximum.\u003c\/li\u003e\n\u003cli\u003eSpeaker outputs on four 4-pole, 5 mm screw-lock captive screw connectors, rated to a 4 ohm minimum load.\u003c\/li\u003e\n\u003cli\u003eInput signal detection threshold of -65 dBu ±3 dB balanced, plus a 2-pole contact-closure standby control port.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eHuddle rooms, classrooms, distributed background music in restaurants and lobbies, paging in clinics and offices, and any zone-heavy design where rack units are scarce.
