The BSS AR-133 has become a classic among active DI boxes. The input is available both as an unbalanced jack, as well as an XLR with a jack loop output.

The PAD switch not only switches on an input attenuation of 20 or 40 dB but also changes the input impedance: while in the 0 dB position 1 MOhm allows trouble-free and low-loss connection of even high-impedance guitar or bass pickups, the impedance at -20 and -40 dB is 47 kOhm. The XLR output is transformer-balanced for load impedances of 600 Ohms or higher.

Power can be supplied from a 9V battery (2 mA) or phantom power (20 - 48 V, 8 mA), and switching to applied phantom power can also be automated. The arched case allows cables to run back underneath the unit from the end for neat cable management.
