Radial Engineering Trim-Two
Passive Stereo DI with Level Control

OUR PART #  TRIM-TWO


The Radial Engineering Trim-Two is a passive direct box designed for use with laptop computers, smart-phones, tablets and other consumer devices where the user has a requirement for a readily available volume control for quick adjustments on stage.

The Trim-Two includes a choice of input connectors that include dual 1/4" jacks, left and right RCA's, and a 3.5mm stereo input. Each pair of connectors is wired in parallel with one another, allowing any of the inputs to be used as stereo thru-puts to feed an alternate signal path such as stage monitors. Inside, a pair of great sounding Eclipse transformers isolates and balances the signal with a linear frequency response from 30 Hz to 20 kHz. Capable of handling levels up to +15dB, these transformers provide typical -10dB consumer electronics with plenty of headroom.

As the Trim-Two is completely passive, no power is required. One merely connects the source to the Trim-Two and the XLR's to the PA System. An easy to access front panel level control makes adjusting the volume a snap, allowing the presenter or performer to quickly change the levels without the aid of a sound technician. The Trim-Two also features a handy Mono/Sum switch, making it easy to connect to mono PA systems or to split the balanced output off to two destinations. Finally a ground lift switch is included at the XLR outputs to further reduce the possibility of buzz or hum.

As with all Radial direct boxes, the Trim-Two features a 14 gauge steel I-beam inner frame and unique book-end outer shell to withstand the abuse of live production. These features all combine to make the Trim-Two a great choice for keyboard players, DJ's and audio-visual presenters that employ a laptop or tablet and demand quick access to a volume control.
