GUIDE TO INSTALLATION AND OPERATION

1 ADC-1722 Dual Analog Audio to AES Converter

1.1 Introduction

The ADC-1722 is a high-quality, 24-bit, analog audio to digital converter which allows conversion of two
stereo analog audio signals to AES type digital signals. Sampling rates can be set to 32, 48 or 96 kHz. AES
outputs can be locked an external reference signal. An internal digital EBU tone generator facilitates
alignment of audio levels. User-defined channel identification data may be encoded in the AES status bits.
An input audio signal status is also available indicating the input signal presence or overload. The ADC-1722
is compatible with both AES3 and AES-3id digital audio standards and is housed in a Densité frame, 2 or 3
RU. A single or double-width rear panel is required.

1.2 Features

• (1 or 2) balanced analog audio inputs

• external reference loop input (Word Clock or AES3-id DARS)

• (2 or 2x2) AES digital audio outputs

• Balanced AES3 or unbalanced AES3-id outputs

• 24-bit A to D conversion

(16, 20 or 24 bits output word length)

• 32, 48 and 96 kHz sampling rates
(Optional VCXO for 44.1/88.2 kHz)

• -96 to +12 dB of level adjustment (in 0.5 dB steps)

• 0 dBFS selectable (0 to +28 dBu, 1 dB steps)

• Internal EBU tone generator

• No signal delay threshold adjustable

• Overload detection and reporting

• Settings and adjustments through frame control panel

• Status LED and remote reporting

• Provides output to Monitoring Switching Bridge option (MSB-1121)

o Not supported for Assy# starting at 0696-1200-400

• Supports REF-1701 or REF-1801 reference card

o jumper selectable for Assy #0696-1200-2xx
o automatic for Assy# starting at 0696-1200-400

2 Installation

2.1 Unpacking

Make sure the following items have been shipped with your ADC-1722. If any of the following items are
missing, contact your distributor or Miranda Technologies Inc.

• ADC-1722 Dual analog audio to AES converter

• ADC-1722-DRP-75 or ADC-1722-DRP-110 Dual Rear Panel, or ADC-1722-SRP-75 or ADC-1722-SRP-110

Single Rear Panel (see figure)

2.2 Installation in the Densité frame

The ADC-1722 and its associated rear connector panel must be mounted in a DENSITÉ frame. It is not
necessary to switch off the frame’s power when installing or removing the panel. See the DENSITÉ Frame
manual for detailed instructions for installing cards and their ass oc iate d rear pan el s.

When a double–width rear panel is used, the module must be installed in the right-most of the two slots
associated with the rear panel in order to mate with the rear-panel connectors. If it is placed in the wrong slot,
the front panel LED will flash red. Move the card to other slot for correct operation. No damage will result to
the card should this occur.

If a card is placed in the wrong slot, its front panel LED will flash red. Move the card to other slot for correct
operation. No damage will result to the card should this occur.

Attention:

For cards with an Assy# 0696-1200-2xx only – if a reference card is installed in the DENSITÉ frame, e.g. a
REF-1701 in slot #20 or a REF-1801 in slot #10, you have to set the JP1 jumper accordingly. Please refer to
the silkscreen on the card for the jumper position. This selection is automatic with an Assy# starting at 0696­1200-400.

Rear Panel Connections

Four different rear panels are available for the ADC-1722. Their layouts are shown in the figure, and the
signal connections are detailed below.

• The double-width rear panels support
dual stereo audio channels

• The single-width rear panels support a
single stereo audio channel.

The rear panel connections are as follows:
ANALOG AUDIO IN (stereo pairs, left & right)

Connect two or four analog audio signals.

AES OUT – digital audio outputs

These connectors carry the output AES signal
(one or two channels depending on the rear).
Connector type depends on impedance:

• Weco for AES3 (bala nced outp ut ) 110Ω

• BNC for AES-3id (unbalanced output) 75Ω

A REF IN – audio reference signal (with loop-through on the double rear only)
Connect an AES-3id or wor d clock signal to one of the connectors.
