The Ultra-DI DI20 is an innovative active 2-channel DI-box/splitter that takes the signal directly from an unbalanced high-impedance output—like an electric guitar—and feeds it directly into a mixing console or recorder. It is ideally suited to augment the traveling gear of musicians (especially guitar/bass players) as well as live/studio/broadcast engineers, installation contractors and studios/live event engineers. The DI20 converts…

The Xdirect is a high quality interface that lets you connect instrument, line, or speaker level signals to a mixer or other balanced input. The high impedance single-ended 1/4” and XLR inputs are buffered and converted, by very low noise active electronics, into an isolated balanced low impedance signal source. The Xdirect has an extremely flat and wide frequency response…

There are times when you will want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. A direct connection between audio equipment can be a challenge though: technical problems crop up that’ll corrupt the signal. The DI600P lets you connect instruments or amplifier outputs of up…

Adapting from Balanced to Unbalanced and Vice-Versa: Problem: You have a stereo output from a CD player (tape deck, VCR, computer sound card or other consumer electronics gear) and you need to connect it to the balanced line inputs of your mixer (EQ or other piece of professional audio equipment). Actually, there are three problems: 1.) Your source…

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…

There are times when you will want to connect certain sound sources straight to other audio gear, be it for a live performance or a studio session. A direct connection between audio equipment can be a challenge though: technical problems crop up that’ll corrupt the signal. The DI400P lets you connect instruments or amplifier outputs. It converts…

The ULTRA-DI PRO DI800 is a professional mains/phantom powered 8-channel DI-box. It converts unbalanced line inputs into balanced outputs, featuring optional mains or phantom powered operation. Its servo balanced operation assures ultra-flat frequency response. Additionally, it allows direct connection to speaker outputs with up to 3,000 Watts. A ground lift switch as well as input attenuation/gain per channel round off…

ULTRA-G GI100: Your secret weapon for direct sound. 

Whether you’re recording or on stage, you need a reliable DI box to get your guitar sound to the console with full dynamics and power—and without noise. Engineered for electric guitar, our GI100 features a switchable speaker simulation designed by Juergen Rath that so realistically emulates a 4 x 12" cabinet you…

The DI4000 gives you four first-class DI channels in one rack space. With two inputs (XLR and 1 /4 " TRS), a balanced output (XLR) and a 1 /4 " link output per channel, up to 40 dB of switchable input attenuation and up to 20 dB of gain, the DI4000 is equipped to deal with virtually any input…

“Hum” in an audio system is often caused by loop effects which act like antennas. These loops can easily pick up a 60 Hz (or higher harmonics) hum transmitted by electrical wiring. Typically, these loops are connected via grounds, more commonly called “ground loops”. The safest way to eliminate unwanted noise is with the CleanBOX II. Some examples of…

The SOLO/610 delivers the classic Putnam 610 console sound to the single channel format in a rugged, highly versatile form factor, at a price every project studio can afford. The all-tube SOLO/610 provides the silky vintage warmth of the original UA 610 console used by artists ranging from Sinatra to Van Halen. The SOLO/610 will flatter the cheapest to…

Not every instrument is made to connect directly to a mixer. Guitars and basses have a lower output signal level, and their output is not balanced. If you plug them straight into a mixer, you have to jack the preamp level to the max just to get a quiet, wimpy sound. Most keyboards have unbalanced outputs, which means if you…

"Boutique" Studio Preamp Performance, without the Price. If you're looking to add eight stellar-sounding mic preamps to your computer audio setup, hard disk recorder or analog rig, look no further. The Onyx 800R is a high-performance, eight-channel rackmount mic preamp with simultaneous analog and 192kHz multi-format digital outputs. Built upon Mackie's flagship Onyx mic preamp circuitry, the 800R…

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…

The RB-UL4 is a 1U rack-mount quad stereo unit for interfacing domestic, or semi-pro unbalanced equipment to professional balanced line levels. The eight RCA unbalanced inputs have an impedance of 10k ohms and are routed to four balanced XLR-3 outputs with an output impedance of <50 ohms. The output…
