Ultra low inrush current - no need for power sequencing — Allows many XTRA
Series amplifiers to be powered on simultaneously without overloading power circuits.
This eliminates the need for power sequencing.
Flexible Conduit Adapter Kit — Suitable for use in other environmental air space in
accordance with Section 300.22, (C) of the National Electrical Code only when used
with optional Flexible Conduit Adapter Kit, part number 70-228-02.
Auto power-down with fast power-up — The amplifiers automatically enter
standby mode (power-down) after one hour of inactivity, dramatically reducing power
consumption. They quickly return to full power status upon signal detection.
Rear panel level controls — Provide attenuation of input signals for setting proper
audio system gain staging as well as two-zone applications. They are located on the
rear panel to prevent unauthorized or accidental tampering of the level adjustments.
Multiple protection circuits — Activate during excessive clipping, thermal overload, or
DC faults to prevent damage to the amplifier and speakers.
Remote standby port — Enables the amplifiers to be remotely powered down when
not in use, reducing operating cost.
Remote volume and mute control port — This port allows the amplifiers to be
remotely controlled using the optional Extron VCM 100 Series volume and mute or
VC 50 volume controllers, and the MLA VC10 series volume control modules.
Bridgeable outputs — The power output of the XPA 1002 can be effectively doubled
by bridging the output. A mono source is wired to both the left and right input while
the output is wired for bridged operation. Bridging allows power output at 200 watts
into 8 ohms or 120 watts into 16 ohms. The minimum load impedance when bridging
is 8 ohms.
Screw lock, 5 mm captive screw speaker connectors — Enable simple, secure
connections with 22 to 14 AWG speaker cables.
Front and rear-mounted signal and protection indication LEDs — Provide
convenient indication of amplifier operation from both sides of an equipment rack.
Internal international power supply — The 100-240 VAC, 50-60 Hz universal power
supply provides worldwide power compatibility.
