Description
The DUALZDirect provides two independent high quality totally passive interfaces that let you connect instrument, line, or speaker level signals to a mixer or other balanced inputs through high performance audio isolation transformers. Each of the high impedance single-ended 1/4″ inputs is converted by a transformer into an isolated, balanced, low impedance signal output. The DUALZDirect’s audio transformers have an extremely flat and wide frequency response and can handle high signal levels. This gives the DUALZDirect a very clean and neutral sound with a wide variety of signal sources and over long signal runs in high noise environments. The input ATTENUATOR switches allow for a wide range of signal levels and the input THRU jacks allows for tapping off of your signal chain. The GROUND LIFT switches let you totally separate the input and output signal grounds, when appropriate, to isolate two systems, thereby reducing hum and ground-loop noise. What further sets the DUALZDirect apart from other “DI” boxes are its extended features and versatility. We have added switchable low pass FILTERs that cut out all very high frequency interference. These Bessel filters on the outputs are placed out of the audio range and are primarily intended to reduce radio frequency interference before it gets into the main system. The filters are very effective in reducing any digital computer noise artifacts when using the DUALZDirect as an interface between a computer-based audio workstation and your monitors. The PHASE INVERT switches, while not normally included with your “run of the mill” DI box, have been added to allow you to switch signal polarity right at the source. This feature is especially handy when you are combining a direct tap with a microphone feed in the mix. The compact black-anodized all aluminum case and it’s passive design allow the DUALZDirect to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J., and virtually any PA application. It’s full feature set, rugged construction, and high-end specifications make the DUALZDirect the obvious choice.

Best D.I. For The MoneyI have tested a number of similar D.I. boxes and this one is my favorite.Firstly this direct box is incredibly small considering that it houses two channels.I was also impressed by it’s frequency response which Ranges less than a dB from 10Hz-30kHzBuild quality is also excellent.Would highly recommend.

Works great! No sound issuesSo far this stereo di is working great for our piano. Beats having to run two separate direct boxes for a stereo channel.

Great DI Box, but…I probably purchased the wrong DI Box. This box is well designed, well made and works fine, BUT… I didn’t realize that it would reduce the signal LEVEL so much !!!! From reading the description, I though we could use this to take an unbalanced ~ 2 Volt Line-Level Signal and convert it to 600 ohm balanced OUT, to send to a powered speaker that is far from the mixing board. We did this, but there was not enough Signal to drive the powered speaker. I call A.R.T. and asked a Tech about the [Turns Ratio] of the transformers and he wasn’t sure, but if it is anything like the Zin-Zout Ratio (50,000 Ohm to 600 Ohm, or less), it will reduce the Voltage OUT by something like 83 times, so 1 Volt IN gives 12 mV OUT (which for us isn’t useful). It would take 40 Volts IN to get 0.5 V OUT. To his credit, the Tech suggested that for our application, what we wanted a different DI box, which ART also makes. It turns out that they make a great many different versions, for all sorts of applications, so I recommend either a visit to the ART Website (or a call to Tech Support), to be certain that the DI Box you pick can do what you want. – Donald Coley –

Good value!I like the High- cut filter to eliminate possible interference from digital devices

Works great – use it at all gigs.I love this DI box. I play both bass and acoustic guitar – I plug both guitars into this (end of pedal chain, with the shortest possible 1/4″ cables) and then run XLR cables to the mixer. Sounds like a clean signal to me – much better than long 1/4″ cables. The unit is nice and small – fits into a side pouch on a backpack. No power required – plug and play. Bass players seem to always get pushed into a corner or way off to the side so this gives me a chance to have a clean signal to the PA.

Great for multimediaWhile a number of DI boxes are available this one is simple, has a filter for use on digital devices others don’t, and doesn’t require phantom. It’s simple and useful!

A Must-Have, Full-Featured DI!I bought the ART DUALZDirect in hopes of taming my Hammond organ’s 6-pin to TS output (WAY too hot). The unit did the job extremely well, without having to engage attenuation at all. Very clean. Also tried the unit after guitar effect unit into amp, and the ground life disposed of the demon hum instantly. When using two microphones to mic an amp, the phase switch worked like a charm. This unit is a must live, or recording. A lot of bang for the buck.

Excellent SoundWhen buying a DI that is less money than you are used to spending on a DI, you have doubts. So far this stereo DI is perfect for our needs. I used it this past weekend to run a stereo signal into our digital mixer from a keyboard. No strange sounds, no buzz, just a clean signal.
