Sidebar 1: Specifications
Description: Network-connected audio converter with two expansion slots for input/output boards. Base unit digital I/O: 8 AES3 I/O (DB-25), 8 ADAT/2 S/PDIF (TosLink), RAVENNA/ AES67 (RJ45), Word Clock (BNC), Sync I/O (DB-15: LTC, MIDI, Video Reference). Base unit analog output: Two headphone (6.35mm, 3.5mm TRS). Voltage (AC): 90V–260V, 47–63Hz. Voltage (DC via optional supply): 10–14V. Max power consumption: 30w. Specifications via headphone-monitoring jacks: THD+N: –106 dB (0.0005%) at 1kHz, 0dBFS. Dynamic range (A-weighted): 118dB. Frequency response: 6Hz–22kHz (+0/– 0.2dB) at 48kHz; 2Hz–44.2Hz (+0/–0.3dB) at 96kHz; 2Hz– 88.1Hz (+0/–0.3dB) at 192kHz. Max output level, high: 15.5dBu (600 ohm load); low: 7.3dBu (16 ohm load). Maximum output power: 200 mWpc (16 ohm load). Output impedance: 20 ohms. Supported sample rates: 44.1–384kHz PCM plus DSD64, 128, and 256.
DA8P option card: Eight-channel D/A converter board based on the ESS ES9028PRO converter chip with balanced outputs via DB-25 (AES59/Tascam Analog pinout). Supports PCM up to 384kHz and DSD up to DSD256. Max line output @ 0dBFS, 24dBu setting: 25dBu +0/–0.5dB; 18dBu setting: 19dBu +0/–0.5dB. Frequency response, +0, –0.3dB, PCM, Fs=48kHz: 0Hz–20kHz; DSD, Fs=2.8224MHz: 0Hz–20kHz; Fs=2.8224MHz: 0Hz–50kHz. Line output impedance (differential): 90 ohms. Dynamic range (20Hz– 20kHz): 124.5dB flat, 127dB A-weighted. THD+N, 1kHz, 0dBFS: –116dB (0.00016%). Crosstalk, 1kHz: –140dB; 20Hz– 20kHz: –115dB. Latency, slow rolloff: 9 samples; sharp rolloff: 35 samples.
