Frequently Asked Questions - AV Direct ART

What is the ART AV Direct used for?

The ART AV Direct is a passive direct box that allows you to connect stereo MP3 players, laptop computers, DVD players, consumer hi-fi, or video machines to a single XLR microphone level input.

What types of inputs does the AV Direct have?

It has stereo RCA, 1/8-inch TRS, and 1/4-inch TRS line inputs, plus 1/4-inch and bare wire pressure clip speaker level inputs.

Can I connect amplified speaker outputs to the AV Direct?

Yes, the speaker level inputs are heavily padded and can accept up to 100 watts @ 8 ohms. The transformer isolated XLR output safely sends the signal to a microphone input.

What is the purpose of the High-Cut Filter?

The switchable 4.8 kHz high-cut filter helps eliminate unwanted high-frequency noise and hiss from the audio signal.

What does the Ground Lift switch do?

The Ground Lift switch disconnects the ground connection between input and output, helping to eliminate ground loops and hum.

Does the AV Direct require external power?

No, it is a passive device and does not require any external power source.

What is the output impedance?

The XLR balanced output has a nominal impedance of 150 ohms at 1 kHz.

What is the frequency response?

The frequency response is 20 Hz to 20 kHz +/- 1 dB, ensuring full audio bandwidth.

How do I use the AV Direct with a microphone input?

Simply connect the XLR output to the microphone input of a mixer, PA system, or recorder. Use the LEVEL control to adjust the volume at the source.

What is the warranty period?

ART provides a 3-year limited warranty to the original purchaser (USA only). Proof of purchase is required for service.

INTRODUCTION:

Thanks for purchasing Applied Research and Technology's AV Direct, offering a superb level of sound quality.

The AV Direct is the ideal solution for any application where stereo MP3 players, laptop computers, consumer DVD players, consumer hifi equipment or video machines have to be connected to a single XLR microphone level input. Unlike standard gender bender cables or DI boxes, the AV Direct can accept virtually any connection and output level (including amplified speaker outputs) and offers remote level control, ideal for setting the volume of your component at the source, rather than in an AV room, audio closet or installation rack.

The AV Direct has stereo RCA, 1/8-inch and 1/4-inch TRS line inputs, as well as a 1/4-inch and bare wire pressure clip speaker level inputs. A switchable 4.8 kHz high-cut filter, ground lift and variable level control allows the AV Direct to effectively filter out any extraneous unwanted noise while offering variable volume control at the source. The speaker level inputs are heavily padded and there is transformer isolation from the XLR output, allowing amplified speaker levels (up to 100 watts @ 8 ohms) to be tapped off, and sent to a microphone level input. A 20 to 20 kHz frequency response ensures the AV Direct will function seamlessly with any high quality audio source.
