Sine Wave, Noise, Polarity. A full range of digital audio test signals for maintenance, repair and calibration of professional audio equipment is generated. User test signals may be stored as uncompressed WAV-files in the DR2 memory. Multi Format SYNC Input. The DR2 accepts AES3, DARS, Word Clock and Video Black Burst (PAL and NTSC) synchronization signals. The input impedance of the sync input may be switched between 75 Ohm, 110 Ohm and High Z. * Channel Status Monitoring. Channel status information can be generated in professional and consumer format and the most important parameters may be manipulated manually. Display of incoming channel status data is also supported. Store Preset Configurations. Up to 10 complete instrument configurations can be stored in the internal flash memory and reloaded for repetitive tasks. The saved settings may also be transferred to other DR2 instruments. Dolby Digital, Dolby E and DTS. * Output Sampling Frequency . XLR, RCA: 32, 44.1, 48, 88.2, 96, 176.4, 192 kHz. Optical: up to 96 kHz. ADAT: up to 48 kHz. Outputs AES3 (110 Ohm) XLR.
