ART DIO AtoD CONVERTER

DIO - A/D Converter Overview

Designed to help ease the transition to the digital world, the DIO offers high resolution stereo
24-bit A/D-D/A conversion at switchable sample rates from 44.1 to 96kHz. In external sync
mode, the DIO?s intelligent synchronization allows for automatic sync with outboard equipment
at sample rates from 22kHz to 100kHz.
The DIO can be used in a wide variety of applications including recording, project, and home studios.
Let the DIO be the interface for your ?classic? analog signal processing gear in an all-digital production
environment. It?s the perfect interface for any digital workstation or computer based recording system
and gets the A/D-D/A conversion process out of the noisy digital environment.
You can use the DIO as your instrument?s direct-to-digital interface, thanks to its high input impedance.
Upgrade the A/D-D/As on your DAT machine or any older digital I/O equipment with the DIO?s high resolution
converters. Get the most out of your dynamic range on new samples and overdubs. You can even
loop thru the DIO to add ?analog? warmth and musicality to an existing digital track.
The latest refinements in ART?s award winning tube pre-amp design are integrated on the front end,
before the A/D converter, for analog gain and dynamic range control. At the clean setting, the tube
circuitry is virtually bypassed and the A/D sees a ?straight wire with gain? signal. As you increase
the control the signal goes from ultra clean and transparent, thru silky, to smooth, to warm, to fat.
At this end the tube becomes the dominant gain element, enhancing lower and mid level signals
and soft limiting peaks and overshoots before they hit the A/D.
This stereo unit provides superior audio conversion in the same compact package as ART?s famous
TubeMP, and like the TubeMP, the DIO?s performance exceeds that of units costing many times its
price. It?s unique combination of features and flexibility will make it a must-have in any audio toolkit.

The Tascam LA-40 MKIII has been primarily designed to provide matching capabilities between professional equipment and semi-professional or consumer equipment. It consists of four RCA inputs and outputs (–10 dBV, unbalanced) as well as four XLR inputs and outputs (+4 dBu/–20 dBu, balanced) which enable the user to connect for instance four tracks of a multitrack recorder (ins and outs) to a balanced mixer ensuring optimum level and impedance matching. Also, a switch matrix allows channels to be linked, utilizing the converter as a distribution amplifier for splitting signals to multiple recorders, or for multizone sound routing applications.

Switches on the bottom panel allow to select a nominal level of +4 dBu or –20 dBu for each channel and ±12 dB trim pots on the front panel make perfect level matching easy. LEDs on the front panel indicate signal presence for each channel. The LA-40 MKIII has also ground lift switches for each channel and a combined master switch to avoid ground loops.
Main Features

    * 4 channels with balanced XLR inputs and unbalanced RCA outputs
    * XLR nominal level selectable between +4 dBu and –20 dBu
