| Description | |||
| The DA210D is an AES/EBU digital distribution amplifier matrix housed in a 1U, 19", rackmount case with integral mains power supply. The unit offers multiple operating configurations to enable sample rate conversions, re-framing to an external reference signal and has a convenient analogue audio monitoring output. | |||
| Features | |||
| Operating Modes: | An internal switch is used to set the DA210D in one of the following modes. | ||
| Mode 1 - One input, ten output distribution amplifier, the input is reclocked for jitter attenuation. | |||
| Mode 2 - As mode 1, but dual one input to five outputs. | |||
| Mode 3 - One input, ten output distribution amplifier, the input is sample rate converted and frame synched to a reference signal applied to input 2. | |||
| Mode 4 - As mode 3, but dual one input to five outputs, with the first input sample rate converted and frame synched to second input. | |||
| Mode 5 - One input, ten output sample rate convertor and distribution amplifier. The input is sample rate converted to provide ten outputs at either 48, 44.1 or 32 kHz from an internal generator. | |||
| Inputs: | Two transformer balanced rear panel XLR inputs with selectable 110/75 ohm input termination. Input 1 and 2 can be directly connected to outputs 2 and 10 respectively, for loop through operation. SPDIF signals can also be wired unbalanced to the inputs. | ||
| Outputs: | Ten transformer balanced rear panel XLR outputs with 110 ohm output impedance. | ||
| Applications | |||
| The DA210D digital distribution amplifier is ideal for use in both audio and video installations where AES/EBU audio distribution is required. Audionics also manufacture a digital audio distribution amplifier card frame. The card frame has twelve distribution amplifiers each with ten outputs and an integral modular power supply. | |||
