DAC 102 • Introduction 1
Introduction
This section gives an overview of the DAC 102 and its features. Topics include:
• About this Guide
• Product Description
• Features
• Application Diagram
About this Guide
This user guide contains installation, configuration, and operating information for the device.
NOTE: Throughout this guide, the general terms “decoder” and “audio decoder” are
used interchangeably to refer to the DAC 102.
Product Description
The Extron DAC 102 audio decoder is a two input, one output digital to analog audio
decoder. It accepts 2-channel LPCM audio signals (up to 192kbps) from either a TOSLINK
or S/PDIF coaxial source and converts the signal to balanced/unbalanced 2-channel audio.
An integrated remote volume control port allows for output level adjustment and mute
control when used with volume controllers such as the VCM series of products.
The DAC 102 bridges digital S/PDIF sources with external analog audio devices such as
amplifiers and audio switchers. It accepts digital audio S/PDIF connections over coaxial
RCA or optical TOSLINK and converts them to 2-channel analog audio. Balanced/
unbalanced analog stereo 2-channel outputs are available over a single 5-pole captive
screw connection. Only uncompressed PCM/LPCM formatted (up to 192kbps) audio
signals are supported as the DAC 102 does not accept multichannel audio and does not
have the ability to downmix. The integrated remote volume control port allows for output
level adjustment and mute when used with analog volume controllers such as the VCM
series of volume controllers.
To accommodate installation in tight locations, the DAC 102 is housed in a small, low profile
1.3 inch tall plastic enclosure with a mini Type B USB connection.

DAC 102 • Introduction 2
Features
• Provides two channel digital audio to analog conversion from a TOSLINK
or coaxial S/PDIF source — TOSLINK takes priority when both digital inputs are

• Balanced and unbalanced analog outputs
• Remote volume port — Compatible with volume controllers such as the MLC 55 RS
VC, MLC 64 RS VC D, MLC 64 RS VC, MLA VC10 Plus, and VCM series
• Small form factor
• Lip sync correction up to 100 ms — Adjustable from 0 to 100 ms in 1 ms steps.
Configurable via SIS commands and PCS.
• ZipClip 25 included
• USB configuration and power port

This section details the installation of the DAC 102, including:
• Installation Overview
• Rear Panel Features
Installation Overview
ATTENTION:
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
• Cette installation doit toujours être conforme aux dispositions applicables du Code
américain de l’électricité (National Electrical Code) ANSI/NFPA 70, article 725, et
du Code canadien de l’électricité, partie 1, section 16. La source d’alimentation ne
devra pas être fi xée de façon permanente à une structure de bâtiment ou à une
structure similaire.
• This product is intended to be powered by a UL Listed power source marked
“Class 2” or “LPS”, output rated 5Vdc or from a USB port on a Listed device.
• Ce produit doit être alimenté par une source d’alimentation certifi ée UL de classe
2 ou LPS, avec une tension nominale 5 Vcc ou depuis un port USB d’un appareil
certifi é.
Follow these steps to install and set up the DAC 102 for operation:
1. Turn off all equipment and disconnect from the power source.
2. If desired, mount the decoder (see Equipment Mounting on page19).
3. Connect source devices via the TOSLINK or S/PDIF RCA inputs.
4. Connect the output of the DAC 102 to an audio amplifier or audio processor (see
figure2, Bon page4).
5. Connect a volume controller (such as a compatible VCM and MLC analog volume
controller) to the 3-pole, 3.5 mm blue captive screw connector (C) for remote volume
control.
6. Connect power to the decoder by connecting the included USB-A to USB mini-B
cable to the rear female USB mini-B port (A). The mini USB port allows the audio
decoder to be powered from a 5 V USB power source.
To configure the unit, connect your computer to the POWER/CONFIG USB mini-B port
(A). Use the Product Configuration Software (PCS) or Simple Instruction Set (SIS) to
adjust settings.
7. Power on the products connected downstream from the DAC 102.

Operation
Audio Delay
The DAC 102 supports up to 100 ms of audio delay for correcting lip sync issues. Lip sync
issues occur when the video content does not match the timing of the audio.
Audio delay can be adjusted from a PC via SIS commands (see Set audio delay on
page18) or PCS (see Output Configuration on page15).
TOSLINK and S/PDIF RCA Inputs
Digital PCM/LPCM 2-channel audio from either coaxial RCA or TOSLINK source devices
can be used.

DAC 102 • Operation 6
Supported digital audio formats
• Supports 2-channel uncompressed digital PCM/LPCM audio at 32 kHz, 44.1 kHz, 48
kHz, 96 kHz, and 192 kHz sample rates at up to 24-bit resolution
• Input signals that are not the PCM/LPCM rates listed above will not be supported.
When incompatible formats are detected, the DAC 102 will mute the output to prevent
damage to speakers downstream.
Input Priority
• Incoming digital audio formats and sample rates are automatically detected.
• Only one input signal can be processed at a time.
• Inputs are automatically switched based on priority and cannot be selected manually.
See the table below for input status, priority, and LED states.
