XTRA Series • Introduction

1-3

Convection cooled — The XTRA Series of ampliers 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 ampliers to be powered on

simultaneously without overloading power circuits. This

eliminates the need for power sequencing.

Flexible Conduit Adapter Kit, part # 70-228-02 — 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 #70-228-02.

Auto-standby with fast power-up — The ampliﬁers

automatically enter into a standby mode 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 ampliers 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.

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 to be output at 200 watts into 8 ohms or 120 watts

into 16 ohms. The minimum load impedance when

bridging is 8 ohms. See chapter 3 for complete wiring

details.

Screw lock, 5 mm captive screw speaker connectors — Enable

simple, secure connections with 22 to 14 AWG speaker

cables.
