INTRODUCTION

Mytek 8X192 ADDA is an 8 channel Analog to Digital and an 8 channel Digital to Analog converter maticoulsly designed to provide the highest quality signal path. No compromises have been made to sound quality, and we feel that this is the best sounding Mytek converter to date. In trial tests in comparison with other hi-end brands this unit provided the same or better sonic performance, which makes it suitable for the most demanding mastering and recording applications.

Users choose Mytek converters primarily for their outstanding sonic quality. The sound of Mytek converters can best be described as "transparent". We design our converters to be as faithful to the original signal as possible, rather than adhering the philosophy of some other manufacturers who offer "analog" or "tube" sounding converters. Mytek converters are designed to be as close to a straight wire as possible,which is especially evident when used at full 24/192 or DSD resolution.

On the Mytek website you can find and download various sound samples to evaluate the 8X192's sound quality and compare it to the sound of other high end converter units. Please log onto: http://www.mytekdigital.com to download samples. Thanks to the wide choice of daughter interface cards (DIO Cards), the 8X192 becomes an 8 channel "digital swiss army knife",which allows the user to adapt converter performance to most studio setups and situations."

In addition to typical converter functions, the Mytek 8X192 features a unique analog mix bus designed with transparency in mind, a monitor section with a mastering grade stepped attenuator, and a hi-end headphone amp.

The built in CX 797 clock generator with multiple wordclock outputs is the best source for stable studio house clock, and the 8x192 will perform best using this internal clock.

SIGNAL FLOW

The 8X192 ADDA has two independent signal paths within the unit. They offer independent signal paths but must operate at the same clock source and sampling frequency. It's recommended that as much as possible the unit should be clocked from its internal CX 797 clock generator. This mode offers minimum jitter allowin for the best performance and system stability. Associated equipment should be slaved to 8X192 clock outputs whenever possible. There is no measurable improvement (rather typically a degradation) when the unit is clocked by external clock generator.

1) The first path is built around the ADC converter and essentially defines what input is selected to be sent to digital outputs. All digital outputs are simultaneous, so if the analog input is engaged, the analog signal is converted to digital and sent to all installed digital outputs.

If the digital input is selected, only digital format conversion is performed, and the signal is then passed to the digital outputs. There is no SRC or any kind of digital processing induced. When operating in DSD mode only the inputs and outputs compatible with DSD format are active.

"2) The second signal path is built around the DAC. It defines what signal is present at the analog outputs. The selected digital signal is converted to analog. If the analog input is selected, it's first converted to digital by the ADC and then sent to the DAC and converted back to analog.

INPUT/OUTPUT GAIN

AND OTHER INTERNAL ADJUSTMENTS

Analog input/output alingment

The 8X192 ADDA analog input/output sensitivity comes as factory default fixed at -15dBFs corresponding to +4dB (OVU=1.228VRMS measured between hot and cold). This gain is optimal for most situations and unless another level "is necessary for systemic reasons, we recommend leaving the gain at the default setting. If the gain has to be changed the appriopriate jumpers and trimpots have to be accessed by lifting the top cover. Please review the drawing on following page.

The gain alignment does not affect audio quality, only input/output sensitivity. A small tweaker or screwdriver is necessary. First you have to arbitrarily decide what will be your studio "0 VU" analog/digital reference level. It is usually between -20 and -14dB. It defines how much headroom is left over the normal operating "0 VU" level. You may set it at the same level as other piece of equipment in your studio.

Step 1 - Analog output alignment

1. Play a digital audio source (DAW generator, test CD etc.) set to approx. 1kHz at the peak operating level you have chosen (let's say you have chosen -18dB).

2. Send the signal from the analog output to the console VU meter. If you don't have a VU meter you can use an AC voltmeter set to measure AC RMS values. "0 VU"at + 4dB corresponds to 1.225 Volts RMS measured between pin hot and pin cold of the output signal.

3.Using a tweaker or a small screwdriver adjust the analog outputs until the VU meter reads "0 VU".

4. Repeat the same for all outputs.

Step 2 - Analog input alingment

1.Set the oscillator in your console at 1kHz and "0 VU". Send the oscillator to the 8X192ADDA analog input."0 VU" at + 4dB corresponds to 1.225 Volts RMS measured between pin 2 and 3 of the output XLRs. If you do not have an analog oscillator, you can use a calibrated analog out of a DA converter and generate a sinewave inside the DAW. Alternatively, if you do not have an oscillator you can use the analog outputs you have just aligned as a source of a sinewave at +4dB (generating sinewave digitally as in step 1).

2.Select the "analog input". Connect a digital meter to a digital output. If you don't have a dedicated digital meter use the most precise meter available in you existing digital recording equipment or DAW.

3. Adjust the analog input level to get appropriate reading of the meter (for example -18dB).

4. Repeat the same for all of the analog inputs.

In this mode both the AD and DA run on the internal clock. This mode provides the lowest jitter and most sonically robust performance. External recorders (such as DAW etc) have to be synchronized either to the AD digital outputs (any format: AES or DIOCARD1 or DIOCARD2) or to the converter Worclock output.

This example shows 44.1 PCM, but any FS can be any selected, including DSD and 128x DSD. Also instead of AES, any other digital input to DA can be selected, depending on the particular system configuration.

Although multibit ADC THD measurements are marginally better, the distribution of distortion subjectively sounds less desirable than in 1 bit converter which tends to exhibit certain silky quality.
