BSS AR-133

The BSS AR-133 (as well as its predecessor, the AR-116) has become a classic among active DI boxes. The input is both unbalanced phone jack, and XLR jack a jack through output run with. About the PAD switch is not only an input attenuation of 20 or 40 dB switched but also changes the input impedance: while in the 0 dB position 1 Mohm problem-free and low-loss connection also allows high-impedance guitar and bass pickups, the impedance at - 20 and -40 dB 47 kOhm. The XLR output is transformer for load impedances of 600 ohms or higher). The power supply battery (<2mA, an on 9V) or phantom power (20 - 48V, <8mA done, the switch also automatically can be phantom power applied to. The special shape enables the bundling of wires under the housing rounding.
