A The exclamation point inside a triangle is intended to alert the user to the presence of important operating, maintenance and servicing instructions in the literature which accompanies the product.

Once again, we’re looking at a facility which has been included primarily as a means of producing more convincing reverb effects, but it does have its place in tailoring the overall sound of the unit, which for those without individual EQ controls on the effects loops on their mixing desks and so on, should prove quite useful.

Qualified service personnel should service the unit in certain situations including without limitation when: I’d have thought they might be tempted to move away from the kind of name which suggests these are simply reverb units. These will be found screwed down to the regualtor heat sink it makes for a convinient ground.

Rather disappointingly, delay time is limited to ms in all but two configurations, and even here a figure of ms represents the upper limit. The can then read the data for use as necessary. Diagram 4 shows the basic timing of these events. On the rear panel of the Midiverb, there are no real surprises: Familiarity with the appearance of this signal on a scope, will greatly facilitate troubleshooting audio problems.

Obviously, a full discussion of this device is beyond the scope of this manual, however, a brief introduction to the device is definitely in order. This is achieved simply by pressing Program and inputting a value directly using the ten buttons sub-labelled There are several important features in the filter to be aware of.

The output of U4 pin 8 has a tap running to R46, a 2N transistor, etc. A The arrowhead symbol on a lightning flash inside a triangle is intended to alert the user to the presence of un-insulated “dangerous voltage” within the enclosed product which may be of sufficient magnitude to constitute a risk of electric shock to persons.


The chorus and flanging effects, though not the most convincing I’ve ever heard, are certainly very usable, especially at the more subtle end of the range.

Danger of fire or electrocution if fuse is incorrectly replaced.

If you value this resource, you can support this project – it really helps! This signal is injected into the signal path at U4 pin Liquid has spilled or objects have fallen into the product, b.

Reverb programming is a law of diminishing returns, and beyond a certain point you can do little to a program which will ultimately benefit the music. All things considered, I think using the new sockets and sticking to the right power adaptor is the best approach. The product shows an inappropriate change in manua, or does not operate normally, or e.

Some important control signals are outlined below.

Input from J7 is R. Quick movements, excessive force or uneven surfaces may overturn the combination which may damage alsis product and rack combination.

On the next cycle, the reverse will occur. Bad power supply rail. Later, the circuit was incorporated into the main PC Board. Your purchase of the Manual shall be for your own ultimate use and shall not be jii purposes of resale or other transfer. It is intended only for the use of those authorized by Alesis. Danger of explosion if battery is incorrectly replaced. The Midiverb III will appear non-functional for approximately 10 seconds after receiving a complete memory dump, with the display showing ” “.

More on this later.

The manufacturers would, I’m sure, argue that this midivefb represented the next logical step in reverb unit design, but I have a suspicion it had something to do with musicians and studio engineers soon realising that having 30 or 40 different reverb patches to play with sounded great, but trying to discern more than about a dozen of them within the context of the average mix alesie damn near impossible. While maual the unit monauraly, the input impedance fixed at K R2, and Mdiiverb, in parallel.

Certainly, this new level of sophistication has made them a viable and cost-effective alternative for guitarists and other instrumentalists – the days of dead 9V batteries and flangers taking the short way off the front of the stage may soon be over. But consider the lot of the designers at a company like Alesis: These two groups are iiu sub-divided to each provide six mono and six stereo effects, varying in intensity – from small to big depth, as the manual so quaintly puts it.


It is also possible for the choke to short to the case top which is grounded. Other than there, and in the power supply, you really can’t do any harm with a scope probe, so explore.

All Trademarks are property of their respective companies. The combination of the product and rack should be moved carefully. It achieves this status by virtue of being programmable – which the Midiverb II is not – but having fewer effects and a slightly less impressive spec than the Quadraverb.

If the address is memory map decoded by U17 to indicate access to the SRAM, it sets up a chain of events. The process again begins as a normal write to memory.

Alesis Midiverb III (MT Mar 90)

The overall decay of each of these effects can be adjusted using the second of the two available parameters, Decay Time. Note at this point that there are two different ASICs. For example, in some configurations the chorus effect is connected directly to the output whilst in others it is applied to the input of the reverb or delay effects. The last of these, EQ, though not, perhaps, an effect per se, is nevertheless highly useful on a unit such as this, as it can be applied individually to the input signal and to any of the other three effects, making it possible to determine the ‘colour’ of the reverb, for example.

This is quite straightforward in operation apart from its use with gated reverb effects where it is used to determine the length of the gated sound, and on reverse reverb where, for obvious reasons, it has no effect at all.

Replace only with the same or equivalent type recommended by the manufacturer.
