User manual APOGEE DA-1000

DA-1000E-20 D/A CONVERTER DA1000E-20 is a portable, stereo, Digital to Analog Converter that provides a professional reference standard for uncolored reference monitoring of digital audio sources. Applications include open reel and video based recorders for CD mastering, DAT Recorders, Hard Disk Recorders, Digital Audio Workstations, multi-track applications, and CD players. The DA1000E-20 features 20 Bit resolution with unequaled sonic performance and versatility. 12v operation makes it ideal for portable use. POGEE'S A Analog Outputs An internal gold pin matrix provides various analog output formats at gold male XLR output connectors, bypassing the pitfalls of automatic balanced/unbalanced circuits. DA-1000E Specifications Quantization--Converter: 20 Bits per sample / 8x oversampling Quantization--Input: 16 Bits per sample Frequency Response: 20Hz­10kHz ±0.025dB, 10kHz­20kHz +0.05/-0.2dB THD + N ­94dB typically@1kHz S/N Ratio: Typically ­106dB flat, ­108.5dB A weighted Crosstalk: Typically better than 110dB, 20-20kHz De-Emphasis: 50uSec/15uSec De-Emphasis Control: Automatic, Override ON, Override Off De-Emphasis Indication: Amber LED indicated De-emphasis Input Sampling Rate: Any frequency from 32kHz to 54kHz via all digital inputs Sampling Rate Indicator: Amber LEDs indicate output sampling rate range for 32kHz, 44kHz, and 48kHz Internal Recovered Clock Jitter: Typically 30 picoseconds RMS Nominal DC Power Input: 12VDC@1100mA Input Voltage Range: +11.0 to +15 Volts DC Input Dropout Voltage: 10.4 Volts DC Low Voltage Indicator: Power LED flashes at <11.5 DC Weight: 1.3Kg (2 lbs 14 oz) Dimensions: L=27.30 x W=14.12 X H=3.96 cm Operating Temperature: 0°C to 40°C (32°F to 104°F) Digital Inputs Standard interfaces include AES/EBU, SPDIF, Optical, Sony SDIF and SDIF-II. Front end digital processing is provided by a high speed custom-configured gate array which extracts the maximum performance from the D/A converters. Converters 8x oversampled digital data drives two 20-bit Digital to Analog converters. These converters eliminate the usual large transitions around zero, thus providing excellent low level performance in addition to the inherent high level performance. Special Filters Award-winning Apogee filter technology is incorporated in this unit to do away with the troublesome high frequency images found in most of today's consumer and professional D/A converters. Low Jitter Clock Like its companion the AD-1000, the DA1000E-20 features Apogee's C768 Low Jitter Clock. The C768 references to external sync sources and regenerates the clock, providing an electronic flywheel effect that greatly reduces short term timing irregularities, or "jitter."
