2 Introduction

Thank you for purchasing the Dynacord DSP 260 Digital Signal Processor. The Dynacord DSP 260 Digital

System Processor is a universal two-input, six-output digital signal processor with the flexibility of

configuration to handle a multitude of audio system needs and applications; installed sound, house of

worship, convention & meeting facilities, concert touring, club, portable sound reinforcement and more.

2.1 DSP 260 Features

The internal routing matrix can be configured as 2-way stereo + full-range, 3-way stereo, 4-way mono +

full-range, 5-way mono + full range, 3-way stereo with a mono sub + full-range, 4-way stereo with mono

sub and low frequency and finally as a freely assignable 2 x 6 matrix router.

The DSP 260 replaces entire racks of signal processors previously needed to properly configure and

control sound reinforcement systems with a single Analog Devices® SHARC™ DSP processor. The

substantial advantages of the DSP 260 over discrete signal processing racks include:

• 24-bit, 48 kHz digital signal path

• No patch cables to fail or add noise

• Optimal gain structure throughout all stages of signal processing; no gain matching from processor to

processor.

• Recallable factory and user presets; instant system reconfiguration for differing applications and per-

formances.

• Easy, intuitive operation and editing with a PC and the DSP 260 Graphic User Interface Application.

Each DSP 260 Digital System Processor includes the following signal processing blocks:

• Input VU Metering

• Analog or AES/EBU inputs

• 24-bit, 48 kHz A/D converters

• Stereo Hi-pass filters

• Stereo 9-band parametric equalizer

• Stereo 31-band graphic equalizer

• Stereo delay

IMPORTANT NOTE:

To achieve optimum performance and guard against damage to the proces-

sor, your sound system or yourself, please read, understand and follow all of

the directions contained in this Owner’s Manual. Failure to do so may result

in improper performance, loss or injury.

3 Controls & Connection

3.1 Front Panel

1 – USB Connector

USB 1.1 port for connection to a PC running Windows XP or Vista. With a connected PC you may run the

DSP 260 Editor Graphic User Interface Application. The DSP 260 can be operated, edited and configured

for installation with an easy to use, intuitive interface. Any available firmware updates downloadable from

www.dynacord.com can be loaded via the USB port as well; allowing for easy in-field updates.

2 – Input Level Meters

The DSP 260 does not itself have input level controls. Proper input level adjustment is accomplished by

setting the output level from the (L / R) bus outputs from the connected mixer (or other audio output

device), as the vast majority of today’s mixer-outputs are dBu calibrated. When the mixer is operating at

optimal levels, so is the DSP 260. The input meters monitor the input level of either analog or AES-EBU

inputs, depending on the input mode selection set in the Setup Menu.

Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights

the +3dBu (green) and / or +6dBu (Yellow) LED indicators. As the DSP 260 is a digital audio device – and

digital clipping produces very unpleasant results, the Clip (red) LED should not light. If the DSP 260’s input

does clip, reduce the output level of the connected mixer. The -6dB PAD button at the rear panel can be

used for adjusting the input level also.

3 – LCD Display

The back-lit, 192 x 32 graphic LCD display allows for operation and editing of the DSP 260 without the

need for an attached PC. The contrast can be set in the Setup Menu for varying lighting conditions and

viewing angles.

The LCD display works in conjunction with Menu buttons, Select buttons and Value buttons - to operate,

navigate and edit the DSP 260’s parameters.

In Run mode, the LCD displays the number and name of the currently selected factory or user preset.

Pressing the Recall or Store buttons switches to their respective menus. Pressing the Edit or Setup menu

buttons switches the display to the last edited parameter.

DSP 260
