The Alesis Quadraverb 2 Dual Channel Octal Processing Master Effects with Digital I/O is the new flagship of the award-winning Alesis effects processing line.
The Sony DPS-V55 is a four channel multi-effect processor with 20 bit quantisation and 48kHz sample rate to yield outstanding audio quality.
Four channel construction – The Sony DPS-V55 is outfitted with four inputs (and outputs) and can route the input signals in a variety of different ways depending on the chosen effect algorithms and program structures.
Flexible effect algorithms and program structures – The Sony DPS-V55 incorporates a total of 45 different effect algorithms divided into three different types: 4ch, 2ch (stereo), and Mono-Pair. Each effect contains several adjustable parameters and can be easily modified. In addition 2ch and/or Mono-Pair effects can be used in combination within a program, and the program structure can be switched between serial and parallel, allowing you to take full advantage of the four channel construction.
User-friendly operating environment – A primary concern when creating the Sony DPS-V55, was to provide an intuitive operating system for creative sound control. All effect parameters can be accessed directly using the EDIT PARAMETER buttons.
Large memory banks – In addition to the 200 different preset programs (numbers 001~200) created by musicians and engineers from around the world (preset memory), there is also room for you to store up to 200 of your own original programs in the user memory (numbers 201~400). We’ve also included a search function so you can recall the programs you need without having to remember their program numbers.
Search function – The search function lets you locate programs you want by specifying the type of effects they contain.
TAP function – The TAP function lets you adjust certain parameters simply by tapping on the ENTER (TAP) button.
MIDI compatibility – The MIDI interface lets you conduct program change and data save operations.
I see people on various forums say this box isn’t so hot and best avoided. I say fine, more for me then. I’ve had mine since 2006 and have found it to be one of the most useful and flexible effects units in my arsenal. It sounds very nice using it’s standalone effects. With the multi-effects it can be a little noisier. Some of the presets are fantastic and most are fantastically weird. I really love the pitch delays, distortion and reverbs. The chorus is outstanding. the vocoder is pretty lame. Compression is workable but difficult without gain reduction metering. Recently my rotary encoder went. But this unit is worth the trouble to repair. Overall this machine provides a ton of unique effects and plenty of unusual colors.
