This Alesis AI-1 is used and in good condition.

The Alesis AI-1 is a straightforward 1U box, at the heart of which is a two-channel sample rate converter. You can feed a 48kHz stereo digital signal in at one end and a 44.1kHz version comes out of the other -- or vice versa. Aside from sample rate conversion, the AI-1 is also able to convert between S/PDIF, AES/EBU and ADAT formats. When working with ADAT, the AI-1 is able to send or receive pairs of ADAT tracks as stereo signals, and the selection of track pairs is made using the AI-1's front panel. The AI-1 is also compatible with the Alesis BRC, and in multiple ADAT systems, the BRC may be used to provide remote control of the AI-1's functions.

Alesis have striven to make the AI-1 as intuitive to use as possible; the front panel hosts buttons for selecting the signal source, the signal destination and, if an ADAT is involved, which pair of tracks is concerned. The AI-1 automatically recognises the source signal's sample rate, and a pair of buttons allow the user to select a destination sample rate of either 48kHz or 44.1kHz. All the buttons include status lamps but, other than the power switch, there's nothing else on the front panel.

The rear panel is, if anything, busier than the front, with in and out connectors in all three digital formats: optical for ADAT; optical and phono for S/PDIF; and XLR for AES/EBU. There's also a BNC connector, which provides a 48kHz clock output, and a pair of ADAT 9-pin sync sockets for use when the AI-1 is hooked into a multiple ADAT/BRC system. In a BRC-driven system, the 48kHz clock feeds into the BRC and the AI-1 is also linked into the ADAT chain using the 9-pin sync connectors. Power comes in via a mains IEC socket, which makes a nice change from the dreaded wall-wart!

Alesis Microverb II 16 Bit Digital Effects Processor Used.

Been in the closet for years. Includes power supply.

Here's some info about it.

"The MICROVERB II represents a clear breakthrough in signal processing technology. Utilizing the Alesis R.l.S.C (Reduced Instruction Set Computer) architecture, the MICROVERB II provides clean, quiet, professional digital reverberation with the cost and simplicity of spring units. The entire digital processing system is contained on a single chip, developed by Alesis' Research Department, specifically for the MICROVERB II. Using high speed complementary-metal-oxide-semiconductor (CMOS) silicon processing, the MICROVERB II chip replaces several circuit cards of components, while consuming very little power.

The reverb programs were developed in our interactive room simulation and development system. Philosophically, the objective of reverberation is to enhance a dramatic performance, adding space, power, depth. Natural spaces tend to sound more pleasing than the simulated reverb types such as springs and plates, and for this reason, we use room terminology in describing our programs. The programs cover a wide range of sizes and qualities, and include such unnatural concepts as gated and reverse types.

The Alesis Microverb II is a revolution in the development of digital reverb in that it represents a phenomenal price/performance ratio, while reducing the physical size from large, bulky hardware to what you can now hold in the palm of your hand without limiting versatility the way a stomp box would. The 16 programs in Microverb II are the distillation of years of exhaustive research by Alesis into the phenomenon of sound as it occurs naturally in space.

From small, intimate room settings to large unobstructed spaces, to useful gated and reverse reverb effects, Microverb II offers a powerful level of sonic flexibility that will expand and polish the sound of any recording. Moreover, its rugged portability, simplicity and convenient input characteristics make it the logical choice for recreating studio quality sound in live performance."

Aphex Aural Exciter Type B Used Vintage

This is from a smoke free studio and original owner in great shape. It's from the 80s.

In 1975 the Aphex Aural Exciter was unleashed upon an unsuspecting studio, broadcast and film industry. Most engineers and producers found that the device gave increased presence, clarity, and a greater perception of 'loudness' without increasing level. Later Aphex Systems introduced their Type B low-cost version of the original Exciter for the masses.

What It Does

The Aphex works on the principle of generating, within its circuits, fourth and fifth harmonics of the input signal which are mixed in with the input signal at the output. It is thought by the psycho-acoustic researchers that these harmonics are the minute cues which our subconscious minds interpret as 'presence' or 'realness'. It is claimed that it is these missing cues that the Aphex Aural Exciter re-creates and adds back to the main signal to change the way in which we perceive what we hear. Other conventional types of processors such as equalisers or reverberation, enhance those parts of the signal that are left when these cues are masked by the recording process. The Aphex Aural Exciter replaces these masked sounds.

Because the harmonics generated are derived from the main signal, they are musically related. The harmonic structure of each sound or instrument, therefore, is strengthened, allowing it to stand out from others. This manifests itself in a perceived increase in clarity or treble boost without giving any measurable increase in level.
 

How It Does It

The main signal going into the Aphex Aural Exciter passes through unchanged. All the processing is done in an outside loop (called a side-chain) and this processed signal is added in very small amounts to the main signal. See Figure 1.
 

Before the signal in the side-chain reaches the harmonic generator, it goes through a tuneable high-pass filter which removes any unwanted low frequency information. The level of this signal is then metered by a multi-coloured LED before it goes to the harmonic generator. The generated harmonics are then added in with the original signal, and the mix varied by the Mix control.

Aphex Aural Exciter Type B

The Aphex Aural Exciter Type B is a 2-channel stereo device which, of course, can be used as two monos. It comes in its 19" rack-mounted form and is 1U high. At the rear of the unit are ¼" jack sockets for input and output signals of both left and right sides. There is also a switch for adjusting the operating level of the unit to match equipment being run at +4 dBV or -10 dBV, the operating level which is appropriate to most home recording equipment. (More of this later.) Both input channels are of high impedance (47k Ohms) and the outputs are of low impedance (150 Ohms). This means that there should be no difficulty interfacing the Aphex with other equipment. The instructions supplied with the unit give a comprehensive guide to various ways of patching the device. It is designed to operate at line levels and, therefore, there is no input suitable for microphone level.

Controls

The controls of the unit are very simple to understand and operate. On the left is the Drive Control which adjusts the amount of gain into the unit. Next to this there is a flashing tri-colour LED which will show mostly green/yellow with occasional flashes of red on peaks. This would indicate a good input level; if the light was consistently green, this would indicate insufficient level into the unit; too much red would indicate overload and possible distortion.

The next control (called Tune) is the adjustment for the hi-pass filter which, as we have said, will roll off any unwanted low frequency information going to the harmonics generator. The tuning of the filter will alter the amount of input level and this will show on the LED. Therefore, it must be used in conjunction with the Drive Control.

The Mix Control adjusts the amount of effect being mixed in with the input signal. As the manufacturers point out and as we found by experimentation, it is easy initially to mix in too much of the device but the in/out switch allows one to make an instant A/B comparison of input and output (original and treated signals).

The Aphex Aural Exciter Model B is a very well constructed, simple to use device which has many interesting applications and areas to explore in studio, cassette duplication room and in sound reinforcement operations. The manufacturers had made the device easily compatible with -10dBV operation which is the level of operating that most people in home recording will be using. At the same time, it is easily switch-able for use at the professional level of +4dBV. There are those, of course, whose mixers have been adjusted for the lower level of operating, who have -10dBV for a reading of 0VU at their group outputs but still have +4 dBV across their insert points.

This was used in a smoke free studio by an occasional musician. (Means he had a real job......) Decided that the software pitch correction was better for him so it was put in the closet. Somehow the power cable got cut. However it was working fine before it was in the closet. So assume it works fine. If not, let us know. Shoud be a simple repair to the power supply.
