    AR133 - Overview

    Signals from electronic instruments such as guitars, keyboards and similar sound sources generally have a low level, high impedance output, which will not interface with the low impedance balanced input found on professional sound mixing consoles. Furthermore these signals cannot be driven up long cable lengths without serious loss of level and degradation.

    The BSS Audio AR-133 DI box converts this signal to a more suitable form without interfering with or modifying the signal at the instrument source, and should provide freedom from ground and power line related problems.

    Passive DI boxes have limited applications as they will inevitably affect the signal source for guitar type applications, and can also have an insertion loss of around 20dB.

    The only safe and predictable way to provide direct feeds from instruments or other sources is by using an Active DI box utilising an input amplifier driving an output transformer.

    The AR-133 fulfills all the requirements of an active DI and more.

    • Features:

      • Switchable input attenuation 0dB for guitar-type pickups: -20dB for line level signals; -40dB for speaker feeds
      • Matches the level and impedance with unity gain without loading the source
      • Can drive signals up long cable lengths
      • Powered from console phantom power or internal battery
      • Automatic switchover to battery if phantom power fails
      • Parallel Link Jack output to feed amplifiers directly
      • Parallel XLR input for converting unbalanced outputs to balanced lines
