275 Active Direct Box
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. |
Phantom or battery powered in a rugged steel chassis, with separate Speaker Level input connector The ARX DI-PLUS represents another major step forward in active direct boxes. Packaged in a single channel stand-alone format, the DI-PLUS represents a fresh look at active D.I. concepts. Precision engineered Ultra quiet, ultra clean circuitry delivers maximum headroom whatever the signal. Premium grade components, plus an all-steel chassis gives excellent hum and noise specifications and superb audio quality in a tough, roadworthy package. Level control The DI-PLUS features a Normal gain high impedance unbalanced input on the front panel, running to a balanced XLR output on the rear. There is also a separate -40dB Speaker Level input for signal coming from the External (auxiliary) speaker output of an amplifier. A a global Pad switch drops both the normal input and the speaker input by a further 20dB, making it suitable for all applications, from the softest keyboard to the hottest broadcast levels. Battery compartment The revolutionary simple 'clamshell' action of the DI-PLUS battery compartment makes battery changing extremely easy, even on the darkest stages. A 9v alkaline battery snaps into a PCB mounted battery holder for fast, secure location. No fragile battery clip leads to break, no tools required, no screws to lose. Production crew heaven! Automatic Phantom switching The DI-PLUS will automatically switch itself to the console's own Phantom Power, if available, and an LED will indicate this mode. Turn the Phantom Power off and it will instantly revert back to battery mode. Rugged all-steel case A lot of direct boxes are fitted into brittle cast alloy cases. Not this one! The tough all-steel inner and outer chassis of the DI-PLUS provide excellent RF/EMF shielding while making it a sturdy, heavy duty unit that is hard to dislodge, and hard to leave behind. Rear panel showing XLR connector, ground lift switch, and captive screw for opening up the unit for battery changing Whether you're a Studio or Live Sound engineer, installation contractor, or broadcast engineer, you want all the dynamics and clarity of the original sound source transferred to the mixing console. The ARX DI-PLUS provides a rugged, no-compromise solution to all direct injection and signal balancing requirements.

DOD AC 275 Active Direct Box with Switchable Ground Lift and Attenuator-2nd Hand- The AC 275 is an active, phantom powered direct box. Unlike a passive DI where the frequency response of the signal can be altered depending on the connected impedance, an active DI buffers the input signal with an amplifier. This assures that the sound source will reach the mixer balanced and noise-free. Housed in a cast alloy chassis, the AC 275 supplies two, high impedance, unbalanced 1/4" jacks and one low impedance balanced XLR jack. It operates with battery or phantom power. Key Features | ?![]() | Active direct box | ?![]() | Allows a hi impedance unbalanced source to directly feed a low impedance balanced input | ?![]() | Flat frequency response | ?![]() | Connects guitar pickups, microphones or electric instruments to a recording or P.A. console without audio quality loss | ?![]() | Internal pad for speaker level input | ?![]() | Operates with battery or phantom power | ?![]() | Ground lift switch eliminates typical ground loop problems | ?![]() | Rugged, road-proof cast alloy chassis |
