The Behringer Ultra-DI Pro DI4000 4-channel Active DI Box gives you four top-shelf DI channels in one rack space. Direct Injection (DI) boxes, of course, let you plug guitars and basses, keyboards, etc. directly into your board. For impedance matching and signal integrity, they\'re indispensable. The DI4000 is a DI on steroids. With its active circuitry, it sports buffered inputs that won\'t pollute your signal (as passive DIs can). Boasting a bevy of boost/attenuation, groundlift, and connectivity options, Behringer\'s Ultra-DI Pro DI4000 is your audio Swiss Army Knife.

The Stewart ADB-1 is a single channel active direct box that allows an unbalanced source to
directly feed a balanced input. Musical instruments, tape recorders, VCRs and sound projectors
can be run "direct" to the mixing console, avoiding unnecessary degradation of sound quality.
The ADB-1 operates on either phantom power or a 9-volt battery.
FEATURES:
Flat response
Low distortion
Low noise
Wide dynamic range
No transformer
RF protection on input and output
Switchable ground isolation
Flush mounted slide switches |
Palmer PAN 03
19" DI Box 4-Channel active
Active 4-channel DI box. Each channel has a jack input with a parallel output for passing through the signal. An attenuation switch (-30 dB) allows either a line or loudspeaker signal to be connected.Active 4 x DI box, 19" format. Technical specitications identicl to the PAN-02, however, the PAN-03 is built for mains operation. All connections and switches are located on the front panel, an additional parallel XLR output is located in back. 19 inch rack-mount format, 1 rack space, 90 mm front to back.

1,6 kg | Standard active DI box. Can be operated with 9 V batteries or 48 V phantom power. High-impedance input; higher output level than with a passive DI box. Active circuitry allows for high input impedance ( 1 meg. ohm) and higher input sensitivity (typical difference between in and out -4 dB). Maximum output impedance with phantom power operation +10 dB. Output: transformer balanced. The special "floating ground" circuitry enables ground lift even during phantom power operation. Metal case 110 x 73 x 42 mm. |
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.
