Introduction About this User Guide

This user guide contains information about the Extron series of full rack width audio power amplifiers. The Extron XTRA™ Series is a family of 1U convection cooled power amplifiers with mono, stereo, and multi-channel outputs. These professional grade amplifiers deliver from 200 to 800 watts of continuous output power and are available for low and high impedance applications. Each model offers professional grade signal-to-noise ratio and THD+N performance. XTRA Series amplifiers are ENERGY STAR® qualified amplifiers with an Extron exclusive, highly efficient, advanced Class D amplifier design. They also feature patented CDRS™ - Class D Ripple Suppression technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. XTRA Series amplifiers are one quarter to one half the size of comparable amplifiers, conserving rack space. The Extron exclusive, high efficiency design generates very little heat and allows the amplifiers to be convection cooled.

XTRA Full Rack Power Amplifier Series • Introduction 1

Features

Extron Patented Class D Ripple Steering (CDRS microphones.

™) technology — CDRS is an Extron patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions, which can interfere with sensitive A/V equipment such as wireless Professional grade signal-to-noise and THD performance — Delivers professional grade performance with 100 dB signal-to-noise ratio and THD of less than 0.1%.

Front and rear panel LED indicators — • Display limiter/protect status when audio limiting or amplifier malfunction occurs.

• Indicate the presence of input signals.

Audio level adjustment — Potentiometers to adjust the audio level from = (full attenuation) to 0 dB (no attenuation).

IEC power switch — Rear panel IEC rocker power switch.

1U full rack enclosure — The capability to deliver full-sized amplifier power in one half the size of many comparable power amplifiers.

High pass filtering — A high pass filter (XPA 2002-70V, XPA 2002-100V, XPA 4002-70V, XPA 2003C-70V, and XPA 2003C-100V only) toggle switch prevents saturation of speaker input transformers by low frequency signals. Saturation can result in severe distortion of the speaker output signal.

Bridged output mode — The XPA 2004 has a toggle switch to input channels 1 and 3 and output each input as a single bridged output channel at twice the power of a single channel. Input 1 is output over the positive terminals of output channels 1 and 2. Input 3 is output over the positive terminals of output channels 3 and 4.

The XPA 4002 has a toggle switch to input channel 1 and output a single bridged output channel at twice the power using the positive terminals of channels 1 and 2. Convection cooled, fanless operation — Ensuring quiet reliable operation. All models generate substantially less heat than similar power amplifer designs.

Automatic clip limiter — Detects actual onset of clipping by comparing input and output waveforms. Gain is automatically reduced with a slow attack and fast release to eliminate clipping. This advanced limiter design protects the speakers from clipping distortion and offers superior sonic characteristics compared to limiters that use signal compression. Rear panel recessed, detented attenuation controls — Provide attenuation of input signals for adjusting audio system gain staging as well as multi-zone applications. They are located on the rear panel to prevent users from tampering with level adjustments.

Remote standby — Standby control that remotely shuts off all amplifier output while power remains active at the amplifier. Power factor correction — Features power factor correction technology that smoothes out the high peak currents of the current draw of the amplifier, thus minimizing the presence of high frequency harmonics on the AC power line, and therefore preventing audible artifacts from being transmitted to other audio equipment in the system. Class 2 wiring — The outputs from the amplifiers support Class 2 wiring that meets UL requirements.

ENERGY STAR ® qualified — All models are ENERGY STAR qualified amplifiers that conserve energy and reduce costs.

Connecting pin 2 to ground (pin 1) places the amplifier in standby mode. Standby mode turns off all outputs, although the amplifier is still receiving power. To Contact Closure Port on Control Device Use the included 2-pin, 3.5 mm captive screw connector to jumper the pins.

G STANDBY

Turn on the amplifier — Reconnect all power cords and switch on all other equipment before powering up the power amplifier. ATTENTION:

The amplifier must be powered up last. The front panel LED of the amplifier should light green.

L’amplificateur doit être allumé en dernier. Le LED situé sur le panneau de l’amplificateur devrait s’allumer en vert.

Adjust the attenuation level using the rear panel adjustment potentiometers (shown below). To adjust the input level of the XPA amplifier, do the following:

a.

If connecting to a source device with a volume control (variable output), ensure that the volume on the source device is 14 18 26 12 1 10 8 0 6 2 14 12 4 2 10 LEVEL 8 0 6 2 4 14 12 3 10 8 0 6 2 4 14 12 4 10 set to its lowest point, then adjust the level of the XPA fully counterclockwise.

8 0 6 2 4

b.

Set the source device’s volume to its maximum volume level. No sound should come out.

c.

Return to the XPA amplifier and raise the level until sound distortion occurs, then lower the level slightly until any distortion disappears. This setting ensures that, whatever the source device volume setting may be, no clipping occurs. NOTE: When setting volume control through a source device, ensure that the volume of the device is set to variable out. Consult the user manual of the device for detailed instructions on its calibration.

Reference Information

This section discusses the mounting instructions for the XPA seires of power amplifiers.

Mounting the XTRA Series of Power Amplifiers

The XPA power amplifiers can be set on a table or mounted on a rack shelf.

Tabletop Use

Four self-adhesive rubber feet are included with the audio amplifier. For tabletop use, attach one foot at each corner of the bottom side of the unit and place the unit in the desired location.

UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the equipment in a rack.

1.

Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (Tma = +122 °F/+50 °C) specified by Extron.

2. 3.

Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading.

4. 5.

Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

XTRA Full Rack Power Amplifier Series • Reference Information 22

Rack Mounting

The XTRA series of audio amplifiers are housed in rack-mountable metal enclosures with pre-attached mounting ears for standard 19-inch racks. Mount the amplifier as follows:

1.

Disconnect all cables and power sources from the amplifier.

2.

Position the amplifier in the mounting rack so that the four slots in the mounting ears are aligned with the rack mounting holes. Use the included mounting screws to fasten the amplifier to the rack (see figure 18 below). ATTENTION:

Never place a load exceeding 40 pounds in weight on top of the rack mounted amplifier.
