The transformer itself is electrically isolated both in the input and output stages, which means it also eliminates ground loops. Passive DIs don’t require any additional power and use a simple transformer to convert a high impedance signal into a low impedance signal. DI boxes solve this problem completely and there are a few types of them that we might be interested in. Guitars have a high impedance signal, and on the contrary, line inputs have low impedance, which means that if you’d connect guitar straight into the line input of a mixer, the signal wouldn’t be strong enough and would, at least, sound completely unnatural. Original DI boxes were developed in the 1960’s to solve the problem of mismatching impedance. DI stands for “direct input” or “direct inject,” depending on how different audio engineers interpret this abbreviation. What is a DI box?Ī DI box is an electronic device that converts an unbalanced guitar level signal to a balanced microphone level signal. Those devices aren’t interchangeable and should be used together in order to achieve the most efficient results. So every time that you need to send, for example, a guitar signal to any line-level input, a DI box is required.Īnd when you need to send a balanced signal to a guitar amplifier, that would be virtually impossible without a reamp box.

Reamp Station costs $479.99 and is available right now from music retailers everywhere. There’s no need to feed it into an amplifier, as the Link circuit makes this pretty clean and easy. One of the coolest uses for Reamp Station is connecting a pedalboard for reamping. There are also in and out insert jacks (called Link In and Link Out), as well as an Amp Out jack Inputs include a ¼” TRS and 3.5mm mini-plug for connecting mobile devices and tablets, a female XLR Reamp In input (with a ground lift button) and ¼” TRS Reamp In, and a male XLR Direct Output (completely with a 180º polarity switch). Finally the Level control allows you to dial in just the right amount of output in the reamp process. A Filter switch allows you to select a flat response, high-pass or low-pass filters. On the business end of the JCR reamper (which is transformer-based and passive), there’s a Mute button that cuts the signal to the Amp output but does not affect the direct output. Since the DI is active, it requires phantom power and a 48V LED indicates the unit is receiving power. There’s also a 15dB pad that can be switched in or out. The DI features an active design with a few new tweaks that include a unity-gain Class-A Buffer switch and circuit on the Thru output, preventing any loading down of passive guitar pickups when connected to an amplifier and preserving the natural tone of the instrument. First of all, Reamp Station is divided into two clearly defined parts labeled DI and JCR (the reamper). ![]()
