Save space and weight by

mounting the DSP-4 onto the

back of most 2-channel DataPort

equipped QSC amplifiers. Or

use multiple DSP-4s as a stand-

alone,rack-mounted DSP solution.

Configurable

The DSP-4’s processing horsepower is dynamically assignable so you

are not limited by a fixed signal chain. Simply use QSC’s powerful PC-

based Signal Manager software to easily configure multiple processing

functions and signal flow with “drag-and-drop” tools.

Cost-effective

The power and flexibility of the DSP-4 eliminates the need for

expensive outboard processing gear, reducing cost and installation time

for almost any application. The compact DSP-4 also plugs directly into

the back of most QSC DataPort-equipped amplifiers for use in systems

where rack space is a premium.

This compact module offers two channels of independent DSP and

attaches to the back of most 2-channel DataPort equipped QSC

amplifiers—without occupying any additional rack space.

Capitalizing on the success of our DSP-3, the second-generation

DSP-4 provides several enhancements in functionality and

performance while also incorporating the universally popular

XLR balanced connectors. These enhancements include new

A/D and D/A converters for improved signal-to-noise performance

and upgraded software that significantly increases the unit’s

operational characteristics.

Powerful

Simple to install, compact, and featuring “set-and-forget” convenience,

the DSP-4’s powerful processor enables you to perform a wide range of

signal processing functions; and with its new A/D and D/A converters,

its noise floor improves. Whether you need speaker crossovers,

EQ, signal delay, or infrasonic filters, the DSP-4 is as flexible as your

system’s needs.

Each channel includes:

• Crossover filtering

• Compression and limiting

• Multiple Parametric EQs

• Precision attenuation

• Shelf filtering

• Mixing

• Multiple Delays (up to 910 ms)

• Tone and noise generation

Configurations The DSP is configured with an easy-to-use software interface. Signal processing icons from the toolbar are dropped onto the workspace and the signal path is routed with simple drawing tools. Signal Manager Advanced “Drag and Drop” Software Configuration DSP configuration is made simple with a PC-based “dragand-drop” software program called Signal Manager. Users can access a DSP “toolbox” and simple drawing tools to configure processing functions and signal flow.
