QSC CX254 4-Channels 250 Watts Professional Power Amplifier 250With4Ohm Channel

  

QSC CX254 4-Channels 250 Watts Professional Power Amplifier 250W/4Ohm Channel - Good condition. The QSC CX254 is a professional 4-channel power amplifier engineered primarily for permanent commercial and venue installations.

It utilizes QSC's proprietary PowerWave (or PowerLight) switching power supply technology, ensuring clean audio, tighter bass, and minimized background noise or hum. Technical Specifications & Power Output. The CX254 is a low-impedance (Low-Z) amplifier capable of flexible channel configurations to fit various sound system needs. Per Channel (8 Ohms): 170 Watts RMS per channel (20 Hz-20 kHz, 0.05% THD).

Per Channel (4 Ohms): 250 Watts RMS per channel (20 Hz-20 kHz, 0.05% THD). Per Channel (2 Ohms): 450 Watts RMS per channel (1 kHz, 1% THD). Bridged Mono (16 Ohms): 340 Watts. Bridged Mono (8 Ohms): 500 Watts. Bridgeable Architecture: Channels 1+2 and 3+4 can be bridged independently to configure the unit as a 4-channel, 3-channel, or 2-channel amplifier.

Compact Integration: Housed in a standard 2 RU rack-mountable chassis that is 14 inches deep, optimizing rack floor space. Active Inrush Limiting: Prevents major electrical surges when turned on, removing the need for costly external power sequencers. HD15 DataPort Connection: Integrated backend connection allows seamless networking, remote control, and system monitoring via the Q-SYS Ecosystem. Security & Tamper Protection: Features 1-dB detented gain control knobs on the back and includes a custom integrated security cover to prevent unauthorized setting changes.

Hardware Protection: Includes comprehensive circuitry defenses against DC damage, infrasonic signals, thermal overload, and short circuits. Audio Inputs: Utilizes detachable Euro-style (Phoenix block) input connectors. Audio Outputs: Features a robust, covered barrier strip output connector to ensure secure speaker wire hookups. Control Switches: Rear-facing DIP switches control internal clip limiters, selectable high-pass filters (33 Hz or 75 Hz), bridge-mono configurations, and parallel operational modes.

R2 Functional Condition: Key Functions Working. 3R Technology is a socially responsible company committed to helping individuals and businesses re-use and recycle electronics safely and responsibly. Our primary mission is to encourage reuse, the best form of recycling. Our operation has helped redistribute this technology to those who are disadvantaged, looking for inexpensive access, or simply seeking to extend the life of their equipment.

We are Responsible Recycling (R2V3) certified which means all items we sell are tested. We are located in Kent, Washington and items can be picked up directly from our facility. Hard drives, solid-state drives, and all data-bearing devices have been wiped according to R2v3 standards. Your refurbished device will contain a used battery. By their nature batteries do not typically have long lives. We test batteries to ensure they are functional and hold a charge, but we do not guarantee the duration of that charge. Local pickups take 1 to 2 days to process.
