Terms Used in this Manual

Features

The terms “amplifier” and “power amplifier” are used interchangeably in this manual to refer to all of the XPA Ultra models.

• Output Power

• XPA U 358 models — 35 watts rms output power per channel, all channels driven.

• XPA U 1004 models — 100 watts rms output power per channel, all channels

driven.

• XPA U 1002 models — 100 watts rms output power per channel, all channels

driven.

• ENERGY STAR® qualified amplifiers — The XPA Ultra Series are ENERGY STAR

qualified amplifiers and energy efficient products that conserve energy and reduce costs.

XPA Ultra Series Power Amplifiers • Introduction 1

• Extron Patented CDRS - Class D Ripple Suppression — 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 wireless microphones.

• 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 — 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. Auto-standby can be disabled if required.

• 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 — The

XPAUltraSeries amplifiers deliver professional grade performance, featuring 100 dB signal-to-noise ratio and THD+N of less than 0.1%.

• Ultra low inrush current at power up - no need for power sequencing —

Allows multiple XPA Ultra Series amplifiers to be powered on simultaneously without overloading power circuits. This eliminates the need for power sequencing.

• Power factor correction - removes harmonic content on AC line — The

XPAUltraSeries amplifiers feature power factor correction technology that smooths out the high peak currents of the amplifiers’ current draw, minimizing the presence of high frequency harmonics on the AC power line, preventing audible artifacts from being transmitted to other audio equipment in the system.

• Rear panel recessed, detented level controls — Provides attenuation of input

signals for adjusting audio system gain staging. These controls are located on the rear panel to prevent tampering with level adjustments. Laser etched markings provide enhanced visibility of settings for ease of configuration.

• Automatic clip limiter — Detects actual onset of clipping. Gain is automatically

reduced without audible artifacts to protect speakers from clipping distortion.

• Multiple protection circuits — Active during output shorts, thermal overload, or DC

faults to prevent damage to the amplifier and speakers.

• Remote standby port — Enables the XPA Ultra Series amplifiers to be remotely

powered down when not in use, reducing operating cost.

XPA Ultra Series Power Amplifiers • Introduction 2

• High pass filter for high impedance models — This selectable filter, available on the

XPA Ultra Series high impedance models, rolls off frequencies below 80 Hz to prevent saturation of speaker transformers.

• 5 mm screw-lock captive screw speaker connectors — Enable simple, secure

connections with 22 to 12 AWG speaker cables.

• Front and rear-mounted signal and protection indication LEDs — Provide

convenient indication of input signal presence and protection circuit activation from both sides of an equipment rack.

• Front panel over-temperature LED — Provides visual indication that the amplifier

temperature has exceeded the optimal value, well in advance of the onset of thermal protection circuitry.

• Internal Extron Everlast Power Supply — Provides worldwide power compatibility,

with high-demonstrated reliability and low power consumption for reduced operating cost.

• Extron Everlast Power Supply is covered by a 7-year parts and labor warranty.

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

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)].

2. 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.

3. 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. 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.

5. 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).

XPA Ultra Series Power Amplifiers • Installation 6

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).

Power Indicator LED — This LED lights:

• Green when the amplifier is receiving full power.

• Amber when the amplifier is in standby mode. Standby mode turns off all outputs

from the amplifier, although the amplifier is still receiving power.

NOTE: Power indicator LED may remain lit amber for a time after the removal of

AC power. This is normal.

Over Temp Indicator LED — This LED lights red when the amplifier exceeds the

recommended operating temperature for optimal lifetime. The LED will turn off after the amplifier has sufficiently cooled down.

Should the LED light, check the following:

• Verify that the placement of the amplifier allows for adequate ventilation and airflow.

• Avoid placing other equipment on top of or below the amplifier.

• Verify that the operating temperature is within the specified range (see Rack

Mounting Ventilation Recommendations on page10).

XPA Ultra Series Power Amplifiers • Operation 15

Limiter/Protect Indicator LEDs — These LEDs (representing their respective output

channels) light red under three circumstances:

• When the output wiring is shorted together.

• When audio clipping occurs, the LED of the corresponding channel blinks once per

clip occurrence.

• When an amplifier channel overheats, the corresponding LED lights. The LEDs do

not light after the amplifier recovers from the overheated condition.

NOTE: These LEDs are also located on the rear panel.

Signal Indicator LEDs — These LEDs (representing their respective output channels)

light green only when an input signal is detected on the corresponding channel.

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

on the corresponding channel (see figure15, C on the previous page).

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.

High Pass Filter Control Port — On XPA U models with high-impedance outputs,

jumper the OFF and G pins together to disable the internal 80 Hz high-pass filter. This function should only be used when high-pass filtering is applied to the signal before it reaches the amplifier.

Remote Port — The 3.5 mm 2-pole captive screw port is used to remotely place the

amplifier into standby. Connecting the Standby pin to the Ground pin places the amplifier in standby mode. Standby mode turns off all output, although the amplifier is still receiving power. Use the included 3.5 mm 2-pole captive screw connector to remotely ground the Standby pin. The power indicator LED lights amber when the amplifier is in standby mode.

NOTE: A 10k ohm resistor is included in the box. If this resistor is connected

between the standby pin and ground, the auto-standby timer is defeated. The standby pin can still be shorted to the ground pin to force the amplifier into standby.

Figure 17. Speaker Output Connectors

ATTENTION:

• Do not tie channel output pins to each other or to ground. Doing so will short

out the outputs, damage the ampliﬁer, or both.

• Ne pas lier les sorties 1 et 2 des canaux entre elles ou à la terre. Les sorties

pourraient être court-circuitées et/ou l’ampliﬁcateur pourrait être endommagé.

• To avoid risk of damage to the ampliﬁer or the speakers, always connect low-

impedance speaker loads (8Ω/4Ω) and high-impedance speaker loads (70V) to the appropriately marked output connectors on the ampliﬁer.

• Pour éviter tout risque de détérioration de l’ampliﬁcateur ou des enceintes,

connectez toujours les charges de l’enceinte faible impédance (8 Ω/ 4 Ω) et les charges de l’enceinte haute impédance (70 V) aux connecteurs de sortie correctement identiﬁés sur l’ampliﬁcateur.

NOTE: You must use Class 2 wiring for this output to comply with UL requirements.

To wire the stereo audio output: Step 1: Strip and insert the speaker wires into the connector and tighten the captive

screws. Be sure to observe correct polarity.

Do not tin the wires!
