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

2-channel DI box/splitter, passive Converts 2 separate unbalanced line inputs (e.g. instruments) into 2 balanced XLR outputs for connecting a mixer Switchable to split mode (input 1 routes the signal to both outputs) Switchable input attenuation: 0 dB, -20 dB, -40 dB Ground-lift switch eliminates ground loop problems 2 signal inputs via XLR/jack combo connectors 2 low-impedance XLR outputs Modern convex housing design Full rubber housing corners for safe operation Cables can be routed under the housing

Behringer DI-400P High-Performance Passive Direct Injection Box

Introducing the Ultra-Compact DI-Boxes from BEHRINGER

There are times when you will want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. A direct connection between audio equipment can be a challenge though: technical problems crop up that?ll corrupt the signal.

The DI400P lets you connect instruments or amplifier outputs. It converts any unbalanced signal to a balanced signal and eliminates unwanted noise. With its high-performance transformer, it also allows you to use very long cables without the loss of high frequencies.

This is the sort of medicine that?ll cure headaches in your studio or on stage.

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

Active DI-Box SM-60

The electronic Direct-Injection Box SM-60 allows direct connection of electronic
music instruments such as keyboards, synthesizers, electric and electronic pianos,
etc. with mixing consoles in PA-systems and in recording studios.
The SM-6 is designed for applications, where a passive DI-Box does not perfom
satisfactorily, i.e., where the output level of a passive DI-Box is too low for the microphone
input section of the mixing desk.
Because the input impedance of the SM-6 is above 5 MOhm, instrument outputs are
not loaded or in any other way adversely affected. The voltage ratio from input to output
is 1: 1 and is always sufficient for connection with any microphone input. Input connectors
are 1/4" phone jacks, output connector is a Switchcraft D3M; output is 600 Ohms,
transformer balanced. The output level may in certain cases overload microphone inputs -
the line input section of the mixing console must then be used for connecting the SM-6.
The unit operates with a 9 V battery or phantom powering from 24 to 48 volts.
