ART AV Direct is an input solution for applications where stereo iPods, laptops, consumer DVD players, HiFi equipment or video machines are required to be connected to a single 3-pin XLR microphone level input. AV Direct ‘can accept virtually any input connection and output level’, including amplified speaker outputs. The passive DI box also offers remote level control for setting the volume of the component at the source.
AV Direct has stereo RCA (phono), 1/8-inch and 6.35mm TRS line level inputs, as well as a 6.35mm and bare wire pressure clip speaker level inputs. A switchable 4.8kHz high cut filter, ground lift and variable level control allow the AV Direct to effectively filter out any extraneous unwanted noise while offering variable volume control at source. The speaker level inputs are ‘heavily padded’ and transformer isolated from the XLR output, allowing amplified speaker level up to 100 watts @ 8 ohms to be tapped off and sent to a microphone level input.
Optional accessories: SM1 microphone stand mount.
Frequency response: 20Hz to 20kHz, +/-1dB. Line level inputs: 1/8-inch TRS, 6.35mm TRS, stereo RCA (phono). Other inputs: 6.35mm/pressure post speaker level inputs. Maximum speaker input: 100W, at 8 Ohms. Output connector: 3-pin XLR, balanced. Controls: Gain, ground lift, high-cut filter. Output impedance: 150 Ohms, nominal at 1kHz. Dimensions (HxWxD): 47 x 117 x 112mm. Weight: 4.6kg
ART PDB is a passive direct injection box designed to connect the outputs of electronic musical instruments or other audio sources, to the balanced inputs of the mixer console and other balanced inputs. PDB also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer.
For guitar and bass, PDB translates the audio into a low impedance, balanced signal required by mixing consoles. For keyboards and line level signals, PDB automatically balances and matches the line level outputs. DJ mixers often supply an unbalanced -10dB signal. PDB converts this signal to a balanced line level signal before it reaches the console, while providing a convenient method of connector transition with the capability to run long cables. PDB also has the ability to accept speaker level inputs from a power amplifier’s output.
Frequency response: 10 Hz – 50 kHz +/- 0.5dB at +4dBu. Output connections: 600 Ohm, 3-pin XLR. Ground lift: Switchable. Input attenuation: Switchable, 0dB, -20dB, -40dB. Instrument input: 50k Ohm. Parallel link jack: 50k Ohms. Dimensions (HxWxD): 76 x 127 x 51mm.
DPDB - Dual channel
ART dPDB is a dual passive direct injection box that allows DI connection of the outputs of electronic musical instruments or other audio sources to the balanced inputs of mixer consoles and other balanced inputs.
The DI box allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer. dPDB features switchable input attenuation from 0 dB, -20dB, and -40dB, a 50k ohm instrument input, 50k ohm parallel link jack, a 600 ohm 3-pin XLR output, and a switchable Ground Lift.

PDB4 - 4-channel
Discontinued
ART PDB4 is a four-channel passive direct box that features four fully transformer isolated direct boxes in a 1U 19-inch rackmount chassis. Inputs and outputs of each of the four channels are isolated to maximize channel separation whilst transformer isolation on each output also helps to eliminate ground loops.
Frequency response: 10 Hz – 50 kHz +/- 0.5dB at +4dBu. Input connections: 6.35mm TS jack, unbalanced. Output connections: 3-pin male XLR, balanced. Input impedance: 50k Ohm. Output impedance: 600 Ohms. Ground lift: Switchable. Input attenuation: Switchable, 0dB, -20dB, -40dB. Chassis type: All steel. Finish: Black. Power requirements: None, totally passive. Dimensions (HxWxD): 44.5 x 483 x 152. Weight: 2.95kg
Zdirect is a totally passive interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input. This is done via an audio isolation transformer.
The high impedance single-ended 6.35mm jack input is converted by the transformer into an isolated balanced low impedance signal source. The Zdirect’s audio transformer has a flat and wide frequency response of 10Hz to 50kHz, and can handle high signal levels while still maintaining an isolated balanced low impedance output - giving the Zdirect a very clean and neutral sound. The input attenuator switches allow for a wide range of signal levels and the input thru jack allows for tapping from your signal chain. A ground lift switch lets you separate the input and output signal grounds, thereby reducing hum and ground-loop noise.
A switchable, 30Hz low-pass filter cuts out all very high frequency interference. This Bessel filter on the output is placed out of the audio range and is primarily intended to reduce radio frequency interference before it gets into the main system. The filter has been designed to reduce any digital computer noise artefacts. A phase invert switch allows the user to switch signal polarity right at the source.
Optional accessories: SM1 microphone stand mount.
Frequency Response: 10Hz -50kHz, +/-0.5dB at +4dBu. THD: 0.01% Typical, at 1kHz, +18dBu, less than 0.05% at 100Hz, +18dBu. Input connections: 6.35mm TRS unbalanced, 50kOhm. Output connections: 3-pin male XLR, balanced, 600Ohms. Output phase: Switchable, normal/invert. Ground lift: Switchable, fully isolates inputs from chassis and output. Input attenuation: Switchable, 0dB, -20dB, -40dB. Filter type/response: Switchable, low-pass, -3dB at 30kHz. Dimensions (HxDxW): 44.5 x 107 x 89. Weight: 0.35 kg.
