Introduction 9341 Functional Description 9341 Functional Description Figure 1-1 shows a functional block diagram of the 9341. The 9341 receives up to eight balanced audio inputs and converts these into up to four AES-3id output pairs. The output timing can be locked to a DARS input timing, black burst or tri-level video reference signal, or the card’s internal clock. The 9341 also provides audio routing that acts as a full audio cross point.
1 9341 Functional Description Audio Timing Function Audio data blocks are sequentially buffered and released per the user-selected timing reference source. The 9341 allows selection from the following reference timing sources: • DARS Input – All outputs can be slaved to a DARS reference when DARS is selected. In this manner, all other inputs will be re-sampled to sync with the DARS channel.
Introduction 9341 Functional Description Audio Down Mixer and Mono Mixer Function (See Figure 1-2.) The Audio Down Mixer function provides for the selection of any five analog audio channel sources serving as Left (L), Right (R), Center (C), Left Surround (Ls), and Right Surround (Rs) individual signals to be multiplexed into a stereo pair (Down Mix Left (DM-L) and Down Mix Right (DM-R)).

Chapter 2 Chapter 2 Installation and Setup Overview This chapter contains the following information: • Installing the 9341 Into a Frame Slot (p. 2-1) • Installing a Rear I/O Module (p. 2-4) • Setting Up 9341 Network Remote Control (p. 2-6) Installing the 9341 Into a Frame Slot CAUTION Heat and power distribution requirements within a frame may dictate specific slot placement of cards.
2 Installing the 9341 Into a Frame Slot Note: If installing the 9341 in a slot with no rear I/O module, an optional Rear I/O Module is required before cabling can be connected. Install the Rear I/O Module as described in Installing a Rear I/O Module (p. 2-4). CAUTION If required, make certain Rear I/O Module(s) are installed before installing the 9341 into the frame slot. Damage to card and/or Rear I/O Module can occur if module installation is attempted with card already installed in slot.
Installation and Setup Installing the 9341 Into a Frame Slot Note: External frame sync reference signals are received by the card over a reference bus on the card frame, and not on any card rear I/O module connectors. The frame has BNC connectors labeled REF 1 and REF 2 which receive the reference signal from an external source such as a house distribution. Note: The 9341 BNC inputs are internally 75-ohm terminated. It is not necessary to terminate unused BNC inputs or outputs. 10. Note: 9341-OM (V4.
2 Installing a Rear I/O Module Installing a Rear I/O Module Note: This procedure is applicable only if a Rear I/O Module is not currently installed in the slot where the 9341 is to be installed. If installing the 9341 in a slot already equipped with a suitable I/O module, omit this procedure. Install a Rear I/O Module as follows: 1. On the frame, determine the slot in which the 9341 is to be installed. 2.
