Crystal-clear, breathtaking, seat-shaking cinema sound is here with our DCA Series Digital Cinema Amplifiers. Five 2-channel and two
4-channel models offer power points from 200 to 1700 watts per channel in a two rack, 21 pound amplifier. With QSC's exclusive PowerLight® switching technology you'll hear ultra-powerful bass and superior highs in every scene.
With technology, DCA amplifiers take your soundtracks to a whole new level. Not only does it give your music bigger bass and cleaner highs, PowerLight also cuts wasted heat and boosts reliability. PowerLight is a switching power supply that provides ample current to the audio power circuitry by charging the supply rails 230,000 times a second through an ultra-low impedance circuit, so unlike high-powered amps with conventional supplies, the audio signal is never starved prematurely, but remains crisp and clean. It virtually eliminates hum and greatly reduces noise, providing a vast dynamic range that can handle the most demanding digital soundtracks without running out of headroom. DCA Series amps also boast a set of useful features such as individually selectable clip limiters and subsonic filters; and stereo, parallel, and bridged mono operation.

The latest advances in sound system technology such as Dolby Digital Surround-EX and tri-amplification require more amplifier channels than ever before. That's why we designed our newest DCA amplifiers to give you four channels of power in a compact package that doesn't eat up precious rack space. And, compared to the cost of two stereo amplifiers, you'll find they leave more room in your budget as well. In addition to their superior performance we've packed these amps with useful features designed specifically for the cinema market.

The DCA 1824 is ideal for surround channels - each channel can power up to four 8 ohms speakers in parallel for a total of up to 16 speakers.
The DCA 1644 is perfect for powering screen channels in small to medium theatres, or for powering mids and highs in tri-amp systems for larger theatres.
DCAs are equipped with a DataPort for use with QSC DCM-Digital Cinema Monitors, a total system solution that greatly reduces labor & wiring costs.

Designed as a cost-effective solution specifically for sound contractors, the ISA Series features seven models including four low impedance models (ISA 280, ISA 450, ISA 750, ISA 1350) rated for 2-ohm operation, and three "Ti" versions with isolated 25, 70 and 100 volt outputs for distributed audio systems (ISA 300Ti, ISA 500Ti, ISA 800Ti). Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.
Unique among distributed sound power amplifiers, the "Ti" versions will drive 8 or 4 ohm loads and a distributed system on the same channel simultaneously. This enables a contractor to reduce the number of required amplifier channels by allowing a limited number of distributed speakers to be attached to the same amp as is powering the main sound system.
Housed in a rugged 3-U chassis, all seven models feature rear panel gain controls for tamper resistant operation with 2 dB detents for quick and repeatable settings. Inputs include both XLR and detachable Euro-style connectors. Outputs feature covered barrier strip connectors for safety agency compliance, and for added versatility, a DataPort V2 (Version 2) terminated with an HD-15 connector is provided for use with DPV2-compatible signal processing accessories such as the XC-3 Crossover, SF-3 Subwoofer Filter, LF-3 Low Frequency Filter and the DSP-3 with external power supply.
Selectable high-pass filters are included to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA Series provide additional protection circuitry including DC, infrasonic, thermal overload, RF and short circuit protection/
On the ISA 750 and ISA 800Ti, class H complementary bipolar output circuitry increases system efficiency by reducing AC power draw and waste heat by 40%. Cooling is accomplished via an automatic variable speed fan, which pulls air from back to front.
*The DataPort connector on this amplifier is not compatible with Q-Sys, BASIS or CM16a.

QSC's Digital Cinema Monitors provide signal processing and monitor functions in a single integrated system. Designed to be used with QSC's Digital Cinema Amplifiers (DCAs), DCMs optimize loudspeaker performance while simplifying cinema sound system wiring and configuration. The DCM 10D and DCM 30D cover cinema systems ranging from three to five screen channels, and are configurable for bi-amp, tri-amp or quad-amp operation. DCMs are also compatible with all cinema processor formats including Dolby Digital Surround-EX and DTS-ES.
Digital Signal Processing
The DCM's digital signal processing capability outperforms traditional analog crossovers for optimized speaker performance. Crossover frequency, parametric equalization, polarity and gain can be precisely adjusted for each speaker in your system. Digital delays, adjustable in 20 µs increments, assure proper acoustical time-alignment of loudspeaker drivers for smooth frequency response, especially critical in three-way and four-way systems. An active emergency bypass crossover with redundant power supply is also included for fail-safe operation.
Less wiring, faster setup
DCMs greatly simplify system wiring and set-up, significantly reducing installation time and labor cost. Input to the DCM is provided via a standard DB-25 cable from the cinema processor. Connections to DCA amplifiers for input and monitor signals are made through a single QSC DataPort/VGA-style cable. All traditional XLR and barrier strip terminations are eliminated.
DCMs also simplify set-up by using a menu-driven, PC-based software program for configuration. The program includes a speaker data file that lists default parameters for popular cinema speaker models. Commonly used configurations can also be saved on a disk, allowing you to quickly load them on other DCMs.
Advanced Monitor Functions
In addition to audio monitoring of amplifier inputs and outputs, DCMs include QSC's exclusive "load fault" detection. DCMs monitor all amplifier outputs and indicate opens and shorts in the speaker system and wiring via LED "load fault" indicators, providing confirmation that all amplifier outputs are functioning properly.
