The Digitech TSR24S Dual Channel Digital Processor, an upgraded version of the 1993-vintage TSR24. The original machine justified its $799 price tag with true stereo operation, custom effects algorithm creation, 18-bit A/D and D/A converters, sampling, two sets of stereo outputs, comprehensive MIDI control, and the fact that it could be used as two discrete stereo processors. In the grand technological tradition of more-for-less, the 'S' version reviewed here retains all this power and adds even more, for £100 less than the original TSR24: balanced audio connections, a handful of new mega-reverbs, chromatic tuner, so-called 'Whammy' pitch-bending, stereo gated reverb, mono and stereo modulated delays, 4-way auto-panner, single and dual phaser, notch and band-pass filters, graphic module linking, enhanced mixer modules, and lastly (and perhaps most significantly) PPC200 parallel processor card 'readiness’. This card effectively doubles your DSP power, allowing twice as many effects to be used at once, adding new algorithms and programs, and doubling sample and delay times.

Physically, the TSR24S is solidly built, which bodes well for live work, and looks very similar to the original TSR24, the only real front panel difference between old and new being that the majority of the S's buttons are green rather than blue. The TSR24S's large number of buttons, divided into six sections, make for a busy front panel, but in practice allow you to move around the operating system more easily. The six sections are as follows:

• Global: utility functions such as LCD contrast, MIDI maps, chromatic tuner and footswitch setups; this section also includes a bypass button. Though not labelled 'Global' on the unit, the TSR's manual refers to this group as such.

• Edit: six buttons used in the creation of custom algorithms.

• FX Modules: when editing, these buttons take you immediately to the parameters of the effect you've selected. With so many effects available, this is an invaluable facility for speedy editing.

• Parameter: a cross-shaped selection of four buttons that scroll through the editable parameters in a program and allow you to change their values.

• Program: another 4-button cross used to select programs, store new programs, and compare between edited and original versions.

• Access: essentially programmable function keys, and you define what they do; for example, you could use them to jump to the parameters you most frequently tweak in a particular program.

All that remains is the data entry knob, the dual input and output level controls, liquid crystal display, LED patch number display, and a variety of status LEDs which indicate MIDI activity, bypass, overload and so on.

"Digitech's S-DISC based processors produce some of the cleanest, most complex reverbs available in affordable packages."

It's been said before, but Digitech's S-DISC based (Static/Dynamic Instruction Set Computer) processors produce some of the cleanest, most complex reverbs available in affordable packages. The TSR24S is no exception: its reverbs offer programmability unavailable at this price elsewhere -- as an example, the ExaVerb preset has an astonishing 28 editable parameters intended to allow you to convincingly recreate acoustic spaces. The reverbs tend to be bright, but not in the metallic way of some Japanese processors, offering clarity and realism instead. The rest of the effects are equally excellent: delays and samples (up to 5 seconds mono; 2.5 seconds stereo) provide subjectively perfect replications of the input signal; choruses and flangers are rich and exciting (perfect for guitar processing); and the EQ modules add a good deal of creative potential.

Noise performance is good, and the NR modules help where the nature of the effect adds unwanted noise. We thought the pitch-shifting modules not quite up to the quality offered by the rest of the effects, which is surprising given Digitech's success with their Vocalist range of harmony processors. Even the Whammy-based effects -- derived from the famed digital dive-bomb control found on certain Digitech guitar products -- are a little lumpy. However, while we wouldn't use the modules as serious harmony or pitch correction tools -- the delays involved and metallic quality are far too obvious -- they can be used effectively for guitar processing or sound effects.
