DESCRIPTION

The DDA124-BNC and DDA224-BNC Digital Audio Distribution Amplifiers are

designed to regenerate, isolate and distribute digital audio data formatted in

accordance with specifications AES3-1992 and IEC 958. This is commonly called

AES/EBU formatting.

The DDA124-BNC is a 1X24 unit with one loop-thru input feeding 24 isolated

outputs. The DDA224-BNC is a Dual 1X12 with two separate loop-thru inputs,

each feeding 12 isolated outputs.

These models use BNC connectors and operate from and drive single-ended 75-

ohm coaxial cable per AES-3id-1995 and are designed to integrate easily into

video facilities.

FEATURES

• Accepts sample rates from 27 to 96kHz

• Displays standard sample rates of 32, 44.1, 48, 88.2, 96 kHz

• Status and error LEDs show clock lock and data validity

• Adjustable input cable equalizers compensate for extremely long cable runs

• Data is relocked and regenerated before low-jitter transmission

• Loop thru transformer balanced and isolated inputs

• Switchable input termination resistors

• Individual isolated 75-ohm BNC outputs

• Single or dual inputs

• Up to 24 BNC outputs

• Quiet, internal linear power supplies

• Attractive, one rack unit package

DESCRIPTION

INPUTS

Incoming AES/EBU formatted digital audio data is applied to input transformers

T8 (T9 for second input channel of dual unit). Inputs are balanced and DC

isolated from ground. Input blocking capacitors C22 (C24) prevent accidental DC

inputs from saturating (and perhaps damaging) the input transformers. Input

termination resistors R25 (R26) at 75 ohms for BNC (and SP/DIF) inputs can be

switched in or out of the circuit with rear panel DIP switches S1a (S1b). Inputs

should always be terminated unless they are looped through to another device or

to another DDA input. The last device or input should always terminate the line.
