Extron Patented CDRS - Class D Ripple Suppression

wireless microphones.

— 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 characteristics of Class D amplifiers, a source of RF emissions which can interfere with sensitive AV equipment such as

Convection cooled, fanless operation - can be stacked without extra rack space for ventilation

— The XPA Ultra Series amplifiers do not require internal fans or vents for cooling, ensuring quiet, reliable operation. They generate substantially less heat than conventional power amplifiers, making them ideal for rack-mount applications where space is at a premium.

Eight channels (XPA U 358 models), four channels (XPA U 1004 models), or two channels (XPA U 1002 models) in a 1U, half rack width enclosure - single and dual rack mount hardware included

— The channel density of the XPA Ultra Series amplifiers reduce rack space requirements for many installations. The included single and side by side rack mount hardware simplifies planning and saves cost.

Defeatable auto-standby with fast wake up

Auto-standby can be disabled if required.

— The XPA Ultra Series amplifiers meet ENERGY STAR qualification requirements with an auto-standby feature that automatically places the amplifier into standby after 25 minutes of inactivity, dramatically reducing power consumption. The XPA Ultra Series amplifiers quickly return to full power status in less than 100 ms upon signal detection, with minimal inrush current.

UL 2043 plenum rated when used with optional Flexible Conduit Adapter Kit

— The XPA Ultra Series amplifiers meet UL 2043 for smoke and heat release for installation within a plenum airspace above a drop ceiling when used with the optional Flexible Conduit Adapter Kit. Above-the-ceiling placement conceals the amplifier to prevent theft, and is convenient for installing equipment when space inside the room is limited.

Professional grade signal-to-noise and THD+N performance

signal-to-noise ratio and THD+N of less than 0.1%.

— The XPA Ultra Series amplifiers deliver professional grade performance, featuring 100 dB

Mounting the XPA Ultra Series Amplifiers

The XPA Ultra Series amplifiers can be mounted in a rack using included rack ears, set on a table, mounted on a rack shelf, or mounted in the plenum space above a ceiling-mounted projector. Additionally, two XPA Ultra Series amplifiers can be connected using the included bridging plate to create a full rack-width unit.

Tabletop Use

Four self-adhesive rubber feet are included with the audio amplifier.

For tabletop use, attach one foot at each corner on the bottom side of the amplifier and place the unit in the desired location.

UL Guidelines for Rack Mounting

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

1. Elevated operating ambient

the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature specified by the manufacturer [Tma = +32 to +122 °F (0 to +50 °C)].

— If installed in a closed or multi-unit rack assembly,

2. 3. Reduced air flow

— Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

Mechanical loading

— Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

4. 5. Circuit overloading

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

Reliable earthing (grounding)

— Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Vent Space Example

Rack Mounting Ventilation Recommendations

Excessive heat can decrease the optimal lifetime of the power amplifier. An over temp indicator LED on the front panel of the amplifier lights red whenever the recommended operating temperature has been exceeded.

To reduce the chances of an over temp condition, the XPA Ultra amplifiers should be arranged in a rack environment such that the environment around the amplifier does not reach or exceed +122 °F (+50 °C). No more than four stacks of XPA Ultra amplifiers should be arranged one-on-top-of-the-other in a rack without an open space between the stacks

(see figure 8 below).

The XPA Ultra can also be arranged above or below another non-XPA Ultra device. In this case, the environment around the amplifier should not reach or exceed +122 °F (+50 °C).

— These LEDs light green only when an input signal is detected

on the corresponding channel (see

D

Attenuation Potentiometers

— Use a small screwdriver (such as the provided Extron Tweeker) to adjust the audio input level for the corresponding channel. The analog potentiometers control the level from ∞ (full attenuation) to 0 dB.

To adjust the attenuation level of the XPA Ultra amplifier, do the following: 1.

If connecting to a source device with a volume control (variable output), ensure that the volume on the source device is set to its lowest point, then adjust the attenuation of the XPA Ultra fully counterclockwise.

2.

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

3.

Return to the XPA Ultra amplifier and raise the attenuation until a 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.
