Passive DI Box
Additional Photos:
The Zdirect is a high quality totally passive interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input thru a high performance audio isolation transformer. The high impedance single-ended 1/4" input is converted by the transformer into an isolated balanced low impedance signal source. The Zdirects audio transformer has an extremely flat and wide frequency response and can handle high signal levels while still maintaining an isolated balanced low impedance output. This gives the Zdirect 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 jack allows for tapping off of your signal chain. The Ground Lift switch lets 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 Zdirect apart from other "DI" boxes are its extended features and versatility. We have added a switchable low pass Filter that 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 is also very effective in reducing any digital computer noise artifacts when using the Zdirect as an interface between a computer based audio workstation and your monitors. The Phase Invert switch, while not normally included with your run of the mill D.I. box, has 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 Zdirect 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 Zdirect the obvious choice.
SPECIFICATIONS:
• Frequency Response: 10Hz 50kHz, +/-.5dB @ +4dBu
• THD: .01% Typical @ 1kHz, +18dBu,

It's an inexpensive DI box -- a transformer, and several switches, in an aluminum case.
For interfacing a synth output, or a mixer output, to a microphone input, it's perfect. There are several levels of attenuation, and a "Lift / Ground" switch to disconnect / connect the "ground" line of the input from the "ground" line of the output.
I'm sure one could spend more, and get something even tougher, with a better-quality transformer. But nobody has complained yet that I lack highs, or lows.

I've owned one of these units for about 6 years. It's been used it to balance computer and smart-device outputs, plus guitar, bass, small mixer and mic output signals - all without issue. The input pads make it flexible with regard to both input and out put signal strength - a handy feature in a home-based project studio. I personally have not missed the gain capabilities of active DIs. I am glad to see they are still available as I intend to buy a second unit shortly.

I bought a few of these for my church. when they work they're great. The problem is that the 1/4 jacks are not mounted to the enclosure, which causes them to pull off of the PCB and not work. I have had to resolder the input jack and run jumpers so that the di box works again. They have a di box that has the input jacks attached to the enclosure and its similarly priced. I'd recommend those above this as it will break

I've had this DI for about 18 months and use it weekly to get my acoustic into a PA. I've also used it as a way of connecting into the XLR jack on a USB interface for Garage Band recording guitars, bass, and e-drums. It's done the job reliably.

Perfect for connecting laptops & mp3 players to pa systems for presentations. You have to be careful with the gnd tab on the XLR connector, someone bent mine.

good features and price but I was using this for acoustic guitar to PA about 2 nights a week and it only lasted about 4 months before the signal dropped dramatically. It's still under warranty and will be replaced but my next DI will be another brand. Radial's more money but seems like a better fit for me.
