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 Yamaha Rev5 is a highly sophisticated digital reverberation and effects system which offers warm, accurate simulations of natural and plate reverberation, extensive control, and basically superior sound quality. With a sampling frequency of 44.1 kHz, it delivers full, flat frequency response from 20 Hz to 20 kHz for exceptionally clean, “transparent” effect sound and a broader control range.
A total of 30 preset effect programs are provided that can be edited, re-titled, and stored in any of 60 RAM user memory locations. Programs 1 through 30 cover a range of reverb, early reflection, delay, modulation, gated reverb and pitch change effects, while programs .91 through .99 provide a unique set of “combination” programs which effectively function as several Yamaha Rev5 units in one.
Individual three-band parametric EQ parameters are provided for each effect program for precise tonal tailoring. In addition to the basic effect and EQ parameters, the Yamaha Rev5 offers a list of “internal parameters” which provide exacting control over the effect sound. The REVERB programs, for example, feature a total of 12 parameters that make it possible to create precisely the required effect.
The Yamaha Rev5 is also MIDI compatible, with a MIDI IN terminal that allows MIDI selection of effect programs, and a switchable MIDI THRU/OUT terminal. When switched to OUT, edited programs stored in internal RAM can be dumped to a MIDI data recorder or other data storage device. Programs thus stored can be reloaded when necessary via the MIDI IN terminal.
As an extra touch of convenience the Yamaha Rev5’s electronically balanced input and output terminals can be switched to match -20 dBm or + 4 dBm line levels – providing compatibility with a broader range of sound equipment.
Full 20 Hz to 20 kHz frequency response for superior sound
Yamaha Rev5 sampling frequency has been increased to 44.1 kHz to provide full, accurate frequency response from 20 Hz to 20 kHz. This extra margin of reproduction precision means exceptionally clean, “transparent” effect sound and a broader control range.
Expanded control parameters and 60 user memory locations
Yamaha has provided an extremely broad range of control over the reverb sound, allowing the operator to precisely simulate almost any desired effect. This same expanded control capability applies to the Yamaha Rev5’s early-reflection, delay and echo, modulation, pitch change and combination effects as well.
Independent digital program EQ in addition to master EQ
In addition to a master three-band sweep equalizer which can be used to shape the overall response of the Yamaha Rev5 effect signal, individual EQ settings are possible for each effect program.
Midi program selection and dump capability
The Yamaha Rev5 features a MIDI In terminal which allows MIDI selection of effect programs, and a switchable MIDI Thru/ Out terminal which serves dual functions. When switched to Thru, it functions as a standard MIDI Thru terminal, re-transmitting MIDI data received at the MIDI In terminal. This facilitates the “daisy-chaining” of MIDI devices. When switched to Out, user-edited programs stored in internal RAM can be dumped to a MIDI data recorder or other data storage device.
Switchable input/output levels
As an extra touch of convenience the Yamaha Rev5’s electronically balanced input and output terminals can be switched to match -20 dBm or +4 dBm line levels-providing compatibility with a broader range of sound equipment.
As in my other reviews on this site, I have written a detailed review on my experience over the years with the Rev 7 from its first appearance (when I first bought mine) to its usability today and how it has stood up against modern compatible reverbs.. as with all these things, some of which can be down to personal taste and different applications to which we use reverberation in music.
As time passes, I have seen a huge reduction in price and desirability in early hardware reverb units. This is now quite apparent with the big lexicons and certainly at the lower end of the market such as the SPX range and Roland’s early SRV range. Having used pretty much most of the reverbs on the market from the early eighties to the mid 90s, I now find myself buying the odd units that I don’t have because they are simply too cheap to pass by. The Yamaha Rev 5, now falls into that category and if you can find a good working one you can pay as little as $200 or less!
For this kind of money, I would challenge anyone to find better value for money. In terms of its usefulness, It needs no introduction or qualification but there are a few things that I would like to mention to anyone that is about to do the same as I have just done. Most people have ever used a range of seve it needs no introduction or qualification but there are a few things that I would like to mention to anyone that is about to do the same as I have just done.
Most people that have used or heard a Rev 7 and SPX (I hope) will already know their sonic qualities. The Rev 5 (in my opinion) offers some subtle improvements in various parameters and better overall bandwidth than its predecessor. Moving on from the techie stuff, I’m still a fan of its predecessor rather than saying the rev five is an obvious replacement. To my ears, the later rev five is certainly cleaner, and the earlier reflections are somewhat improved, but it’s a personal preference as to whether they are better or not? I certainly am happy to have both units for different options.
From a technical point of you, one thing that I have discovered, is there is a definitive fault in the two digit LED failing on quite a few units that have come up for sale! Indeed, my own unit had a failed LED display and I managed to buy a complete unit that was already being scrapped on eBay and managed to salvage the parts to get mine going! If you can find a good working one, then they are well worth the money., but check out the LED and the LCD display (although that is very simple to replace) before you buy one.
I really liked my time with the Yamaha Rev5, it has many useful reverbs and the highly regarded Symphonic patch that is so revered on the SPX90. I probably should have kept it as I now miss it, so that has gotta mean something.
