The QSC RMX1450a Low-Z Power Amplifier is designed to meet the needs of sound contractors. It features PowerLight technology with specific features to meet the requirements of fixed installations. High output power, versatile loading options, high thermal capacity and proven reliability, make this amp a suitable solution to any permanently installed sound system.
The amp provides direct 70V capability ranging from 250-1000W per channel for distributed audio systems. It is equipped with many contractor-specific features including 1 dB detented gain controls for repeatable settings and a custom security cover for tamper-proof installation. Active inrush limiting eliminates AC inrush current, cutting the need for power sequencers.
It also includes an HD15 Data Port connector to interface with Q-Sys and QSControl networked audio systems, for remote amplifier monitoring and control.
This amplifier gives you tighter bass and clean, transparent highs, cuts waste heat, boosts reliability, and gets rid of unwanted noise and hum. PowerLight is a switching power supply technology providing ample current to the audio power circuitry by charging the supply rails 230,000 times a second through an ultra-low impedance circuit. Thus, the audio signal is never starved prematurely and remains crisp and clean.
With each channel direct-driving 70V loads up to 600W, or 1200W on a 140V line in bridged mono, and having the right connector set for ease of wiring, the CX602V is suitable for distributed-line installation applications.
