The ADB 1 active injection box provides impedance and signal matching for direct connection of instruments to mixers and amplifiers.
When using ADB 1, the signal coming from the input is regulated by an amplifier. The input impedance is high, so it does not affect the signal. The output impedance is balanced, so it is much less susceptible to hum and noise. Thus, the impedances of the source and the mixer or amplifier used are independent.
It allows equipment linking, -20dB + -20 dB attenuation and GND/Linft selector.
