DDA416-XLR Manual

AIR TEMPERATURE AND HUMIDITY

Normal operation of this unit is warranted under ambient conditions defined by EN 60721-3-3, set IE32, value 3K3. The most important conditions of this standard are ambient temperature +5 to +40°C, relative humidity 5% to 85% (with no ice or condensation), absolute humidity 1 to 25 g/m3 and rate of temperature change <0.5°C per minute. Care should be taken to avoid operation outside these limits or erratic operation may result.

DESCRIPTION

The ATI Model DDA416-XLR gives you four independent 1X4 AES/EBU Digital Audio Distribution Amplifiers, each one capable of handling AES3 audio with sample rates from 32 to 192 kHz. Operation of the unit is simple and straightforward, and it is housed in a rugged 2U rack mount enclosure. All audio connections are made directly to the unit’s rear panel XLR connectors, and no special breakout cables are required.

The DDA416-XLR features flexible signal routing. Rear panel accessible DIP switches let you assign each bank of 4 outputs to any of the 4 inputs. This lets you configure the DDA as a Dual 1X8 or a 1X16. Other asymmetrical routing combinations, such as 1X4 plus 1X12, are also possible. Alarm LEDs indicate fault occurring on any input, regardless of the audio routing.

The ultra-low jitter performance of the DDA416-XLR makes it an exceptional performer in any critical audio application. It is ruggedly designed for years of professional service.

INPUTS

Incoming AES/EBU formatted digital audio data is applied to individual input transformers. Inputs are always terminated at 110 ohms.

OUTPUTS

AES/EBU XLR Outputs 1 through 4, 5 through 8, 9 through 12 and 13 through 16 operate as individual groups. Each or any of these groups may be driven from the following input sources, as selected via rear panel DIP switches:

1. AES/EBU Input 1

2. AES/EBU Input 2

3. AES/EBU Input 3

4. AES/EBU Input 4

It is not necessary to terminate unused outputs, as each is individually isolated. Cable routing should be kept clear of AC lines and other noise-producing wiring.

AC Input Connector for socket IEC 320/C13. Power cord is supplied. Note that voltage selection is via jumpers on main circuit board. Units are supplied wired for 115VAC or 230VAC, as specified at time of order. Power transformer primary windings are paralleled for 115VAC or wired in series for 230VAC. Internal jumpers allow field modification if necessary. See below for voltage conversion instructions.

DDA416-XLR Manual

INSTALLATION

LOCATION

To avoid addition of jitter (timing variations) to the output clock signals, which could cause noise and distortion or loss of synchronization in the recovered audio, avoid locating the DDA in close proximity to a high energy, high frequency switching type power supply or a power amplifier that utilizes a switching supply. If possible, do not power both devices from the same AC power line.

POWER

If it is necessary to convert a unit wired for 115VAC to 230VAC operation, unplug the unit from the power source, remove the cover mounting screws and locate the jumpers next to the power transformer. Clip the jumpers 1-2 and 3-4 (don’t unsolder), jumper from 2-3 carefully soldering together the free ends of 2-3 previously clipped. This procedure is recommended to avoid soldering damage to the multi-layer PC board.

WIRING

XLR inputs require special controlled impedance, 110 ohm, low loss, foil shielded, twisted pair cables. Standard audio cable is not recommended except for runs of only a few feet. Belden and most other cable manufacturers offer special digital audio cabling for this application. Keep cable length as short as possible.
