Product Details

The Digirator DR2 is a reference grade digital audio signal generator with transformer balanced AES3, S/PDIF, TOS-Link and ADAT outputs. The generator offers a comprehensive set of audio test signals and surround sound test sequences for verification and adjustment of professional Dolby Digital, Dolby E and DTS installations. The internal low jitter clock generator can be synchronized to AES3, DARS, Word Clock and Video signals. Measurement of channel transparency, channel propagation delay and sample frequency is supported.

  • Handheld digital source
  • Improves surround sound
  • Occupies broadcast lines
  • Calibrated generator
  • Free online updates

    DR2 Features:
    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
    The DR2 wave file player can play back multi channel bit stream files. A set of 5.1 test sequences for the verification and optimization of surround sound equipment and installations is stored on the unit’s flash disc.

    DR2 Measurement Functions:
    Channel Transparency Check
    The DR2 tests whether a transmission channel is transparent for non linear PCM signals and indicates if Dolby E, Dolby Digital and/or DTS bit streams can pass. This test is also suitable for any digital audio recording device.
    Channel Delay Measurement
    The propagation delay between any DR2 digital audio output and the XLR sync input (which accepts AES3 signals) may be measured and displayed in seconds or video frames.
