Page 5: Overview
7700 MultiFrame Manual 7707AT Multi-Channel AES Fiber Transmitter OVERVIEW The 7707AT AES Transmitter extends multiple channels of AES audio over a single fiber optic link. The 7707AT-8U version interfaces to 8 channels of unbalanced AES, while the 7707AT-8 version accommodates unbalanced or balanced AES. The 7707AT-8U-DB has DB-25 connections for unbalanced audio that are backwards compatible with 7705AT-8 The 7707AT-16 version interfaces to 16 channels of unbalanced or balanced AES. -
Page 6: Table 1: Typical Application Configurations
7700 MultiFrame Manual 7707AT Multi-Channel AES Fiber Transmitter Features: • Accommodates eight or sixteen AES audio signals. • 7707AT-8 and 7707AT-16 versions provide interface to balanced or unbalanced signals. • 7707AT-8U version provides interface to unbalanced signals via convenient BNC connections. -

Page 8: Installation
7700 MultiFrame Manual 7707AT Multi-Channel AES Fiber Transmitter INSTALLATION The 7707AT series modules come with a companion rear plate that has AES audio connections and an SC/PC (shown), ST/PC or FC/PC optical connector. The 7707AT-8 and 7707AT-16 versions provide AES connections via multi-pin removable terminal blocks. -

Page 13: Card-Edge Monitoring And Control
7700 MultiFrame Manual 7707AT Multi-Channel AES Fiber Transmitter CARD-EDGE MONITORING AND CONTROL The 7707AT has eight or sixteen LED status indicators and a 4-digit dot-matrix display on the front card- edge to show operational status of the card at a glance. The card-edge pushbutton and toggle switch are used to select various indications to the dot-matrix display. -
Page 14: Card-Edge Display And Controls
7700 MultiFrame Manual 7707AT Multi-Channel AES Fiber Transmitter CH:01 to CH:xx Each of these green LED’s indicate the signal presence of the respective AES input channel. Signal presence indication considers X and Y preambles in processed AES. 4.2. CARD-EDGE DISPLAY AND CONTROLS Additional signal and status monitoring is provided via the 4-digit dot-matrix display located at the card- edge. -
Page 15: Displaying The Aes Audio Sample Rate
7700 MultiFrame Manual 7707AT Multi-Channel AES Fiber Transmitter 4.2.1. Displaying the AES Audio Sample Rate The 7707AT can detect and indicate 32KHz, 44.1KHz, and 48KHz sample rates. Sample rate indication is accommodated through the card-edge interface or VistaLINK . To display the sample rate to the card- edge select the RATE indication in menu level 1. -
