With added functionality and enhanced audio performance, the AR-133 has been
designed to be more affordable for musicians, studios and PA companies.
The unit includes phantom power and battery supplies as standard. Should the
phantom power from the console fail or be accidentally switched off, the AR-133
automatically switches over to the internal 9V battery providing uninterrupted use.
The unit is housed in a rugged aluminium extrusion case, with robust polyurethane
end-cheeks which give the AR-133 a very distinctive look.
Input connectors are both 1/4″ jack sockets and an XLR socket, the latter meaning
that the AR-133 can be used to convert unbalanced signals to a balanced output on
XLRs throughout.
The arched case allows cables to run back underneath the unit from the end for neat
cable management.
Input attenuation is 0, -20 or -40dB, making the box suitable for instrument, line or
amplifier levels on inputs. On the output side, a ground-lift switch is provided for quick
solutions to ground-loop problems.
The AR-133 uses an enhanced version of the same audio path as the AR-116, now
regarded by many people as a reference standard. The sound quality is legendary,
particularly on acoustic and bass guitars.
Numerous applications can be satisfied by the AR-133. For example, as well as the
traditional guitar use, the AR-133 can be used with keyboards, DJ consoles, amplifier
outputs, and other electronic sources.An additional bonus is the ability to use the AR-133
as an active balancing device.

Phantom or battery powered in a rugged steel chassis
The ARX DI-PLUS 2 represents another major step forward in active direct boxes. Packaged in a single channel stand-alone format, the DI-PLUS 2 represents a fresh look at active stereo 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. Accurate Left and Right channel level matching keeps the stereo image centred.
Level control The DI-PLUS 2 features two high impedance unbalanced inputs on the front panel, running to balanced XLR outputs on the rear. A a global Pad switch drops inputs by 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 2 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 2 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 2 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 Left and Right XLR connectors, ground lift switch, battery check switch and LED, plus phantom power On LED 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,clarity and stereo information of the original sound source transferred to the mixing console. The ARX DI-PLUS 2 provides a rugged, no-compromise solution to all stereo direct injection and signal balancing requirements.

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
