	DI unit at AllExperts
		A DI unit or DI box is an electronic device that connects a high impedance line level signal that uses an unbalanced cable with a 1/4" phone plug to a low impedance mic level input that uses a balanced cable and XLR connector.
		DI units are extensively used with professional and semi-professional PA systems and in sound recording studios.
		Active DI units require a power source, which is normally provided by batteries, by phantom power, or both.

	DI unit
		A DI unit or DI box is an electronic device designed for connecting a piece of equipment with an electronic audio output to a standard microphone or line level input.
		A passive DI unit typically consists of an audio transformer used as a balun.
		The cheaper passive DI units are susceptible to hum, and passive units tend to be less versatile than active.

		This type of unit is much too expensive for the home aquarist, at least one on a budget, but the same theory of operation occurs with less expensive DI systems available at the local hardware store or a national water company such as Culligan (Figure 3).
		DI units are easy to install with some having adapters that hook-up to a kitchen or bathroom faucet.
		RO units are designed to work all the time so your water requirements should be determined beforehand and a unit that produces the amount of water you desire purchased.

		When dealing with electric bass or acoustic guitar, a DI is most often preferrable to using a microphone on an amplifier.
		The signal path from the instrument should go into the DI unit and should then pass through to any sort of instrument amplifier.
		DI's commonly have a ground lift it is good to try flipping it to minimize buzz.

	Water purification for salt water aquarium fish tanks (Site not responding. Last check: 2007-10-23)
		DI units are 100% water efficient with no waste water, and are typically rated in terms of grains of capacity (a grain is 0.065 grams).
		Since the water entering the DI unit can be 50 times purer than tapwater, the DI unit can process 50 times as much before the resins are exhausted, reducing the replacement or recharging cost of the DI unit.
		Using two DI units in tandem, moving the 2nd in as a replacement for an exhausted 1st unit, and replacing the 2nd unit with a new unit will insure that no undesirable elements "break through" the exhausted 1st unit and enter your supply.

	Harmony Central®: Paul J. Cox Systems Introduces Active DI Units
		The active DI systems may be used to transform low-level, noisy, unbalanced audio signals such as keyboard, midi module, drum machine or sequencer outputs into much more desirable clean balanced +4dB signals, with improvements to the sonic quality.
		The DI systems are available in a variety of configurations to suit all applications, from standalone 8-channel to customized rack-mounting multi-channel units with integrated patching capabilities, front or rear panel connectors, ground lift switching and custom pinout wiring.
		Eight-channel systems are available either as standalone floor or counter-top units with top-mounted 1/4-inch inputs, ground lift switches and multipin outputs, or as a wall-mount or permanently installed unit incorporating multipin connectors for inputs and outputs.

		Depending on the models purchased, they can come with any number of "stages", some units even have UV stages for sterilization, but for our purposes, a simple "home use" unit will do just fine.
		There are only but 2 or 3 manufacturers of the RO membranes, which are then bought by the makers of RO units to put within their units.
		The larger units use a membrane that is not as "fine" as the smaller units, thus allowing more pollutants to pass through them.

		Your DI columns may be installed inline with a bypass to allow the normal circulation flow of your pump to your aquarium and only a small sampling of water is passed through the DI columns.

	-s0da-'s Reef - RO/DI Unit installation
		Now, the problem with my hook-up was, the place where I wanted my RO/DI unit secured, was too far from the main water line (the one that comes with the unit is usually only 6 feet), so I had to buy extra hose, and a 1/4" hose extension adapter.
		If you're unit comes with (or you purchase one) a TDS meter, this is also easy to install.
		Different models could potentially have different parts/steps/etc. Also, each unit it different, but for the most part, you will have to toss out the first 50 or so gallons, as the unit will be brand new, and the packaging chemicals for the filters will need to be rinsed clean through the unit.

		Or that they don't mic the amp, but run you into the desk via the DI and you still have onstage sound (which is usual).
		But I am a little lost too on the whole amp+DI thing, do they want you to run DI with no backline, that would indeed be odd as I've never run into that request and have been giggin the last 2.5 years with over 100 shows.
		Another option would be to use a pedal tuner in the chain before the DI or on a dry output as tallchap stated.

		This curing process is, in its shortest form, simply a period of time to allow dead and dying organisms on the rock a chance to decay.
		The penalty is that a relatively large, high pressure (read expensive and power hungry) dedicated water pump is mandatory for the venturi unit to inject sufficient amounts of air.
		A CC unit must sum in electricity consumption for the water pump and air pump (usually small) plus air stone and diaphragm replacement.

		I know this unit can be used to filter my tap water to make it 'reef ready' but I noticed on the description of the item, that it can filter 'saltwater'.
		The resin in the unit has only changed color about 1/3 of the way after running a hundred or so gallons thru it, so I don't think that the resins would be a problem.
		I like the fact that deionization (DI) units are less wasteful of water but I do not want to deal with the dangerous chemicals involved with recharging DI units.
