The DOD AC240 is a passive, four to one resistance mixer. Each of the four 1/4" unbalanced inputs have individual level controls, which feed one unbalanced 1/4" output. The AC240 can also be run in reverse to provide a one in, to four out splitter. This is all housed in a rugged alloy cast chassis.

The DOD AC260 is a passive direct box. It converts high impedance to low impedance, or vice versa. Housed in the cast alloy chassis are two high impedance, unbalanced 1/4" jacks, and one low impedance balanced XLR jack. The conversion is done via an internal transformer.

The DOD AC265 stagehand is a passive direct box used to convert unbalanced high impedance signals to balanced low impedance signals, and vice versa. The AC265 includes a switchable ground lift as well as a selectable dB pad. This pad provides an attenuation choice of 0. -12, or -40 dB.

The DOD Ac270 is a simple A/B box. It provides switching from one source, to two destinations, or two sources to one destination. The switching is done via a mechanical push/push switch. Source and destination connections are all unbalanced 1/4" jacks.

The DOD AC275 is an active direct box offering high to low impedance conversions. It can accept high impedance line level signals, or powered speaker outputs to provide a low impedance feed tapped from in-between the amp and the speaker cabinet. The AC275 also includes a switchable ground lift and dB pad, as well as operating on battery or phantom power.
