รายละเอียดสินค้า
- Inputs: Balanced or unbalanced on 3.5 mm, 3-pole captive screw connectors
- Speaker Outputs: Screw-lock, 5 mm, 2-pole captive screw connectors
- Two models with 800 watts rms output power per model:
2 x 400 watts @ 4 ohms; 2 x 200 watts @ 8 ohms; 1 x 800 watts @ 8 ohms (bridged)
2 x 400 watts @ 70 volts — The XPA 4002 is designed for use in large environments, for powering a large quantity of high impedance distributed speakers, high powered paging horns, or large speaker cabinets. - ENERGY STAR® qualified amplifier — The XPA 4002 is an ENERGY STAR qualified amplifier and energy efficient product that conserves energy and reduces costs.
- Professional grade signal-to-noise and THD+N performance — The XPA 4002 delivers professional grade peformance with 100 dB signal-to-noise ratio and 0.1% THD+N.
- 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 characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive AV equipment such as wireless microphones.
- Convection cooled, fanless operation — The XPA 4002 does not require internal fans or vents for cooling, ensuring quiet, reliable operation. It generates substantially less heat than conventional power amplifiers, making it ideal for rack-mount applications.
- Ultra low inrush current - no need for power sequencing — Allows multiple XTRA 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 4002 features power factor correction technology that smoothes out the high peak currents of the amplifier’s current draw, 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.
- Rack-mountable 1U, full rack width enclosure — With the capability to deliver full-sized amplifier power in one half the size of many comparable power amplifiers, the XPA 4002 reduces rack space requirements for many installations.
- Auto power-down with fast power-up — The XPA 4002 meets ENERGY STAR qualification requirements with an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, dramatically reducing power consumption. It quickly returns to full power status in less than one second upon signal detection.
- Rear panel recessed, detented level 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.
- 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.
- Multiple protection circuits — Activate during output shorts, thermal overload, or DC faults to prevent damage to the amplifier and speakers.
- Remote standby port — Enables the XPA 4002 to be remotely powered down when not in use, reducing operating cost.
- High pass filter for high impedance models — This switch selectable filter, available on the 70 volt model, rolls off frequencies below 80 Hz to prevent saturation of speaker transformers.
- Bridgeable output for low impedance model — The power output of the XPA 4002 4 ohm / 8 ohm model can be effectively doubled by bridging the output. When the bridging switch is engaged, a mono source is wired to input 1 while the output is wired for bridged operation. Bridging allows power to be output at 800 watts into 8 ohms or 400 watts into 16 ohms. The minimum load impedance when bridging is 8 ohms. See manual for complete wiring details.
- 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 enclosure temperature has exceeded the optimal value, well in advance of the onset of thermal protection circuitry.
- Internal universal power supply — The 100-240 VAC, 50/60 Hz, international power supply provides worldwide power compatibility.
