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…

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…

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…

“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…

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

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…

Two channel, very high quality passive D.I. box, housed in the same all steel box used for our active models. It features a jack input socket, and link output for connection to an on-stage combo etc. Two wide band low distortion transformers provide a balanced 600 ohm output to an XLR. A ground lift switch is fitted, and the unit…

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…

Use the TAPCO DB-1B passive DI box to connect your guitar or bass directly to your mixer - without losing tone due to impedance mismatches, low levels, and 60-cycle hum. Thru/Out jack lets you send a clean signal to a mixer, plus an onstage amplifier, for greater control during live performance. Available in passive and active models. …

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…
