SPDIF & TOS level to AES 3 conversion

This handy little unit has been developed to interface between Equipment that offers either SPDIF 75 ohm unbalanced OP, or TOS optical OPs.

An elegant feature is the automatic change over between SPDIF or TOS operation, with no adjustment; the only proviso being that no attempt is made to use both inputs simultaneously!

The converter does NOT attempt to alter the protocol of the data stream so, "what goes in, comes out". It does however provide an interface that accurately matches the SPDIF and TOS links, and provides both level and impedance conversion so that Equipment with an AES 3 protocol input is correctly driven.

The converter uses an external 5 volt power supply, and connectors are provided on both the front and rear faces so that several units can be "looped" together. Power drain is minimal, about 50mA at +5V, so many cards may be driven from a single PSU if required.

M3 hankbushes are provided on the bottom so that the stainless steel case may be securely mounted for mobile use, or of course the free-issue Velcro pads used for less stressful mounting requirements.

Please note that this Unit has replaced our previous, SPDIF ONLY Model 356.

Hi, Just to let you know that I connected it to my CD player and DAC

and it does exactly what it says on the tin.

It worked like a dream. Brilliant. Just marvellous.

Many MANY thanks....."P.W" Southampton

Hi. I just got a chance to hook up my SPDIF to AES box. It works perfectly!

What a nice piece of gear.

I will recommend it to everyone!

Thanks!............."G.R" Birmingham.
