The Radial Trim-Two is a simple yet very effective passive direct box that provides the user with the ability to quickly adjust the volume using a variable input trim control. The magic lies in the custom-made Eclipse transformer that produces less than 0.05% distortion with a +10dB source. This makes the Trim-Two a great choice for interfacing laptops and tablets with PA systems for AV presentations or live events.
The design begins with a choice of inputs including dual ¼" jacks, left and right RCAs and a stereo 3.5mm input. These are wired in parallel to allow the signal to be split off to feed an alternate signal path such as monitors. Inside, two great sounding Eclipse transformers do the work of isolating and balancing the signal. These 'passive engines' deliver a linear frequency response from 20Hz to 18kHz and are capable of handling up to +15dB signal levels thus providing typical -10dB consumer-level devices with plenty of headroom. An easy access front panel stereo level control makes adjusting the volume a snap. A handy stereo-to-mono switch makes it easy to reduce the output channel count or send the same balanced signal to two destinations at once. Transformers provide galvanic isolation between the source and the destination and are extremely effective at eliminating hum and buzz caused by ground loops. This is augmented with a ground lift switch at the XLR outputs. One merely connects the source to the Trim-Two and then the male XLR outputs to the PA system. As the Trim-Two is completely passive, no power is required.
