Extron Electronics XTRA Series - Manual (Page 8)

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 amplifiers. CDRS enables Extron power amplifiers to be
situated near wireless AV devices without RF interference.
Convection cooled — The XTRA Series of amplifiers 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 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.
Auto-standby with fast power-up — The amplifiers 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 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 — Allows the XPA 1002 series 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 wiring instructions on page
19 ).
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.
