• Highly eficient Class D ampliier design — The XTRA Series of ampliiers
generate substantially less heat than conventional ampliier designs, making them
ideal for installation in equipment racks and lecterns with very limited ventilation. They
consume 10 watts when idle and less than 1 watt in standby mode.
• Extron patented CDRS — Class D ripple suppression — A patented, exclusive
technology from Extron that eliminates the high frequency switching ripple and EMI
emissions found in typical Class D ampliiers. CDRS enables Extron power ampliiers
to be situated near wireless AV devices without RF interference.
• Convection cooled — The XTRA Series of ampliiers are convection cooled without
the need for fans, ensuring quiet, reliable operation.
• Ultra low inrush current — no need for power sequencing — Allows many
XTRA series ampliiers 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.
• Auto-standby with fast power-up — The ampliiers automatically enter into a
standby mode after 25 minutes of inactivity, + or - 5 minutes, dramatically reducing
power consumption. They quickly return to full power status upon signal detection.
• Rear panel attenuation (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 — Activates during excessive clipping, output shorts,
thermal overload, or DC faults to prevent damage to the ampliier and speakers.
• Remote standby port — Enables the ampliiers to be remotely powered down when
not in use, reducing operating cost.
• Remote volume and mute control port — This port allows the XPA 1002,
XPA 1002 Plus, and the XPA 2001 series to be remotely controlled using the optional
Extron VCM 100 Series volume and mute or VC 50 volume controllers.
• Bridgeable outputs — The power output of the XPA 1002 and XPA 1002 Plus 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
to be output at 200 watts into 8 ohms. The minimum load impedance when bridging
is 8 ohms (see the
Bridged Mono Output
• Front and rear-mounted signal and protection indication LEDs — Provide
convenient indication of ampliier 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.
