Overview
The WZ-AD96 and 96M AD Converters create a new world to digital
recording, authoring and editing. The AD Converter eases analog materials
to interface with various digital systems such as DVD multi-track authoring,
PC-based DAW and MDM recording, and the input expansion in a digital
mixer system, with flexible hookup.
It accepts an 8-channel analog input and finally supplies digital audio data in
the Dual-Wire or Single-Wire format based on the AES3 Hi-Sampling standard
to meet your system requirements. Beside an ADAT output as the standard,
the TDIF output and Dual AES output cards are available as an option.
Pnasonic engineers have pursued what the real sound quality is and what
makes high fidelity sound for years. All technologies we have learned are
condensed in the 1-U compact body; custom LSI, circuit designs and layouts,
component selections and so forth.

Features
Features
High Accuracy, high fidelity 8 channel/24 bit¡96 kHz ADC
• Dclta-Sigma system, 128-time Over-Sampling AD Converter is adopted.
Wide dynamic range of 118 dB is achieved.
• Delay time among channels and units is negligible small.
• The solid capacitor used in the reference circuit is a key to stable
conversion that is stable to long time use and high frequencies.
• Simplified Pre-Amplifier with Balanced In and Out
• Analog dynamic range of 126 dB (AD96) /120 dB (AD96M) is achieved
thanks to fewer stages of low distortion amplifier.
• A discrete transistor circuit realizes low noise, E.I.N. of 128 dBu.
• Crosstalk of 114 dB is accomplished by optimum layout and taking
both advantages of discrete parts and SMD.
• Carefully selected components; low-leakage transformer, hi-precision
metalized resistors, customized capacitors and even one screw;
contribute sound fidelity.
•
High bit, high sampling interface
• Compatible to MTRs and HDR in Dual-Wire AES mode, and to T.c
electronics and other major processor units in Single-Wire Hi-Speed
mode.
• ADAT Interface, 24 bit/48 kH2/8 channel or 24 bic96 kHz/4 channel,
easy interface with HDR and DAW
• TDIF Interface, 24 bit/96 kHz/4 channel, easy interface with 24 bit
TDRS to build a 4-track Hi-speed/Hi-Sampling recording system.
• Sync to external Wbrdclock ranging from 44.1 -6% up to 96 +6%.
• Reference level adjustable from among -14, -16, -18 and -20 dBFS by
DIP switch.
• Wordclock output can be set to follow either the sampling frequency
or AES output signal .
Features
Low noise power supply and separate grounding system
• Discrete power circuit contributes to low impedance and low noise.
• Unchangeable idea of low impedance and separate layout is applied to
grounding.
• Thick PCB pattern for power and ground, and large capacitors in
each channel assure channel separation.
• Special made screws (patented) assure continuity of ground level,
beside the GND terminal provided on the rear panel.
Precise Meters
• 0.05 dB accuracy digital meters, 10 point (AD96) and 3 point of
Signal/Reference/Peak (AD96M), Zoom and Adjust mode provided to
AD96.
• Peak detection adjustable for either use of a peak meter or clip meter.
• Reference level selected by the DIP switch to meet the connected
device’s.
10
Features
Low power consumption
• Digital circuits are condensed in a small packed custom LSI with a 3 3
V operation voltage. This reduces power dissipation greatly and also
interference between digital and analog.
• Power consumption as an 8-channel unit; 18 W (AD96)/19 W (AD96M);
is comparable or even less to a 2-channel unit.
• Well considered temperature distribution not to affect on the AD
converter.
Customizing
• DIP switch on the rear panel enables custom settings beside major
operation and monitoring set on the front panel.
• Key lock function protects your customized settings from mis-operation
and mischief.
• Dither is added to reduce significant distortion in audio output when l6 or
20 bit is selected.
