Dual 1x12 XLR Distribution Amp


DDA-212 Series 2 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 or AES3. The Model DDA-212XLR uses XLR connectors and operates from and drives a 110-ohm balanced shielded twisted pair distribution system per AES3-1992.

Main Features:
• Configurable for Dual 1X6 or 2-Input 1X12 operation
• Accepts sample rates from 27 to 192kHz
• Displays standard sample rates of 32, 44.1, 48, 88.2, 96, 176.4 and 192 kHz
• Displays Word Length of 16, 18, 20 and 24 bit
• Status and error LEDs show clock lock and data validity
• Automatic input equalizers compensate for very long cable runs
• Switchable re-clocking regenerates stable data before distribution
• Loop thru transformer balanced and isolated inputs
• Switchable input termination
• Individual, transformer balanced and isolated 110-ohm XLR outputs
• Two front-panel-selectable inputs
• 12 outputs
• Front panel control locking system
• Quiet, internal linear power supply (DDA-212XLR Input voltage is 115Vac. But it has a 230Vac version also, just add “230V” at the end of the model number to order it).
• Attractive and rugged 1RU package

• CONNECTORS: XLR female or BNC; paralleled input connectors for loop-thru expansion
• LEVEL: XLR 0.2Vp-p minimum; BNC 0.1Vp-p minimum
• IMPEDANCE: Transformer isolated, balanced and floating, XLR 110 ohms, BNC 75 ohms; terminating resistors may be switched in or out via front panel control
• CABLE LENGTH: > 1000 feet (300 meters) of 110 ohm cable with equalizer; 75 ohm coax allows longer runs
• EQUALIZER: Automatic EQ for long lines via front panel push button
• CLOCK: Regenerated from input signal with dual mode PLL or non-reclocked to preserve Surround coding, switchable
• CONNECTORS: XLR Male or BNC Female, 6 or 12 depending on model
• LEVEL: XLR 4Vp-p loaded; BNC 2Vp-p loaded
• IMPEDANCE: XLR 110 ohms, balanced and transformer isolated; BNC 75 ohms, unbalanced
• OUTPUT JITTER: < 300 picoseconds peak to peak.
• PROPAGATION DELAY: < 25 nanoseconds
• INPUT FAULT: (DDA-212 Only) Input 1, Input 2; identifies input with error condition
• INPUT SAMPLE RATE: 32, 44.1, 48, 88.2, 96, 176.4 and 192 kHz
• INPUT WORD LENGTH: 16, 18, 20 and 24 bits
• INPUT DIGITAL ERRORS: Bi-Phase/Parity, Validity, Non-Linear PCM, DTS-CD Signal
• MODE: Pro, Consumer
• INPUT CABLE EQ: Locked, Enabled
• INPUT SELECT: DDA-106: 1, 2; DDA-212: 1, Bridge, 2
• POWER: LED indicates power is applied
• POWER: Internal Supply, 115/230VAC (selectable via internal jumper) ±10%, 50/60Hz, 10VA, IEC320 3 pin connector
• SIZE: 19” W x 1.75“ H x 8.5” D; 9 lbs.
• WARRANTY: Limited, One Year Warranty
