Inter-M QD-4480

Quad Amplifier

 

Overview

The QD-4240/4480/4960 Are Four-Channel Amplifiers Capable Of Driving 4Ω Loads. Their Clean Sound Quality

Makes Them Ideal For Permanent Installation In Professional PA Systems Or For Portable Use For Live Performances.

 

Inputs Are XLR/TRS “Combo” Connectors; Outputs Are Via Rugged Five-Way Binding Post Connectors.

Clip-Limiters Are Supplied On Each Channel To Help Prevent Distortion Due To Excessive Signal Levels. All Units

Have Soft-Start Protection Circuitry And Feature Power, Signal, Protection, And Clip Indicators On The Front Panel.

 

For Added Versatility, They May Be Operated In Stereo, Dual Mono Or Bridged Mono Mode. The Quad Series

Amplifiers Are Powered By 100-120VAC Or 220-240VAC 50/60Hz(Depending On Country Requirements) And

Are Packaged In 3.5” (2RU) High Rack Mount Enclosures.

Feature

- FOUR CHANNEL AMPLIFIER

  Four Channels In A Single Chassis.

- ADVANCED PROTECTION CIRCUITRY

  Thermal Overload Protection, DC Detection Circuitry And Power-On Delay Help Protect Your Amplifier And System

- BRIDGED MONO OPERATION

  Can Operate In Monaural Mode For High-Power And Performance.

- SLIM DESIGN, COMPACT SIZE

  Streamlined Design Fits In A Compact 2RU Space.

- INTEGRATED CROSSOVER

  The QX-4960 Features A Built-In Crossover For Easy And Convenient System Integration.
