Professional active injection box, provides a balanced low impedance signal from an unbalanced high impedance signal, has three attenuation levels, and ground disconnection. The entrance has a parallel jack to bypass it. It is powered by 9v batteries or by phantom.
Offering clear audio quality along with tour-ready reliability, the BSS AR-133 is an active DI box capable of being powered by a 9V.o battery via phantom.
It has a -20dB and -40dB attenuator to control the “hottest” signals, which makes the AR-133 suitable for instrument, line or amplifier levels. A ground switch has also been installed to help remove the buzz from the power grid and ground loop problems.
Parallel jack inputs allow linking to bass and keyboard configurations prior to stage amplification, with a balanced XLR input and output allowing for a professional connection in audio systems.
