Peak Indicators (Inputs 1~8): These red LEDs will light whenever input channel signal levels reach +14dB (6dB below clipping). Use this feature to aid in the adjustment of the Trim controls (see below).

Trims (Inputs 1~8): These screw-driver adjustable controls set the channel input gain (0dB ~ +60dB) to compensate for different source levels. This gain range will accomodate most microphone or line level signals. For best performance, adjust these controls so the channel Peak Indicators flash only on occasional peaks.

Rotary Encoder & LCD Display: This control and display are used for initial setup of the AudiaEXPI unit. When power is first applied to the unit, the display will cycle through a product description, followed by a title screen. Press the control to enter setup. Rotate the control to make a selection, then press the control again to edit that selection. Additional levels of selection may be available using this same routine. Some edits will require a choice of 'OK' or 'CANCEL. Some selections are only informational, and cannot be edited. Select 'BACK' to return to a previous level, and select '→' to advance. Primary selections are as follows

: BUNDLE NUMBER (CobraNet bundle number to logic input assignments); COBRANET LATENCY (dependent upon CobraNet firmware); PHANTOM POWER (assigns phantom power to inputs); PASSWORD PROTECT (prohibits unauthorized tampering); TITLE DISPLAY (personalized: 2 lines with 8 characters each); ABOUT (serial#, version#, and Ethernet address information).

Mic/Line Inputs: These eight mic/line analog audio inputs are provided on balanced plug-in barrier-strip connectors. For unbalanced input, wire high to (+) and ground to both (-) & (

). For use with condenser microphones, +48 volt phantom power is available at these

inputs (see Rotary Encoder above). Logic Inputs: These eight Logic Inputs allow remote control of CobraNet bundle number assignment (see CobraNet below). Bundle

numbers can be assigned to Logic Inputs using the front panel Rotary Encoder (see above), and can then be selected via external contactclosures (wired from the corresponding logic inputs to ground). Bundle numbers are used to route digital audio signals to specific devices in a system network.

CobraNet: These two RJ45 connectors provide the CobraNet digital audio interface. CobraNet allows multiple AUDIA units to share digital audio (and DSP resources) on a system network. This also allows AUDIA units to be used with CobraNet compliant devices from other manufacturers. A 10/100Base-T Ethernet switch (not hub) is required when networking multiple units. The maximum distance between any unit and an Ethernet switch is 100 meters. Additional Ethernet switches, or even fiber-optics, can be used to further extend distances between units on a system network. The primary and secondary CobraNet ports are redundant. CobraNet supports 64 channels of digital audio (32-in & 32-out) over Fast Ethernet, using CAT-5 cable. CobraNet transmits (32) channels of digital audio on (4) 'bundles' of (8) channels each. The same is true for receiving digital audio over CobraNet. Bundle numbers are used to determine where digital audio is transmitted and received. Typically, 'unicast' bundle numbers (256~61,439) are used to exchange digital audio between two specific devices. With 'unicast' bundles, each CobraNet device can transmit to no more than (4) other devices within a network. With 'multicast' bundle numbers (1~255), digital audio can be exchanged with multiple devices. Due to network delay, CobraNet has a limitation of seven (7) 'hops' (one-way transmissions) within a network.

In order to integrate AudiaEXPI into a AUDIA system, an EXPI (or CobraNet) input block must first be placed into the design layout. AUDIA units intended to receive digital audio from the AudiaEXPI must have their CobraNet jacks connected to the same network. Both the AudiaEXPI unit (hardware) and the EXPI input block (software) must be assigned matching bundle numbers, before digital audio can be successfully exchanged. AudiaEXPI bundle number assignment can be changed in real-time to allow routing of digital audio to different EXPI input blocks within the system. CobraNet Latency settings must be identical in all devices, system-wide. Also, unicast and multicast bundle numbers can be used to route digital audio to individual or multiple EXPI input blocks. Similar considerations may also apply when using AudiaEXPI with other CobraNet compliant systems or devices. AudiaEXPI and AudiaEXPO can exchange digital audio directly (outside of a system network) using either a simple 'cross-over' CAT5 cable or an Ethernet switch.

APPLICATIONS

Hotel with Sound Reinforcement in Multiple Banquet/Conference Rooms

This application demonstrates the use of AUDIA in a hotel conference/banquet facility. This is a networked system using one AudiaFLEX 10x12CM

left stereo speaker

unit and three AudiaEXPI 8-Input Expander units (forty-two inputs, twelve outputs, CobraNet). An example system diagram is shown on the next page.

Each room has four microphones and two stereo line inputs, which are connected to an AudiaEXPI located within the room. This is beneficial because stereo line input signals are typically 'unbalanced' and, as such, should not be routed over long distances. The AudiaEXPI converts these signals to digital audio, and transmits them back to the main equipment rack via CobraNet. Additionally, CobraNet affords the necessary isolation to help avoid ground loops

stereo input #1

left stereo speaker

between active components within the individual rooms and back at the main equipment rack. CobraNet also saves on the labor and expense of wiring, by transmitting all signals from a given room over a single CAT5 cable.

Only three of the rooms utilize an AudiaEXPI locally. The fourth room houses the main equipment rack, which includes an AudiaFLEX 10x12CM. The AudiaFLEX unit accommodates the eight inputs from

stereo input #1

this room, as well as two inputs from centralized paging and background music. The AudiaFLEX unit also provides twelve system outputs: mono speech and stereo program for each of the four rooms. These outputs are feeding the two MCA8050 multichannel amplifiers.

One MCA8050 amplifier has eight channels which are operating as four stereo pairs, providing up to 50 watts per channel to drive the stereo program speakers in each of the four rooms. The other MCA8050 amplifier has eight channels which have been bridged in pairs, essentially creating four channels of 100 watts each. With four TDT100 transformers installed internally, this MCA8050 is prepared to drive the (speech related) 70 volt distibuted speaker system in each of the four rooms.

CobraNet from the AudiaEXPI units to the AudiaFLEX unit is tied together through an Ethernet switch. This allows sharing of digital audio signals (CobraNet) on a network. The maximum distance between any AUDIA unit and an Ethernet switch is 300 feet. Therefore, this system can span up to 600 feet between the main equipment rack and any of the rooms. Additional Ethernet switches, or even fiberoptics, can be used to further extend distances between units on the network.

All mixing and processing of signals is done back at the AudiaFLEX unit in the main equipment rack. In the system design, each room is provided with an Auto Mixer (4x1) for the microphones and a Router (4x2) for stereo source selection. A Room Combiner allows proper sharing of audio and control data amongst the Auto Mixers, and a Matrix Mixer (8x8) is provided to facilitate proper stereo source routing for each of the various room configurations. Duckers allow page-override of local and backgound music signals. Levelers are utilized on all microphone inputs (to provide consistent volume levels), and equalizers are utilized at all outputs (to compensate for room acoustics and enhance intelligibility).

Various remote control options are available. Volume 8, Select 8, and Volume/Select 8 rotary encoder panels may be used to provide volume, source selection, and even room combining functions. A Logic Box could instead provide room combining via external switches

(on the room partitions or on a custom control panel), and would also allow control of external equipment (such as lighting, speakers, sources, etc.). Control behavior is programmable, and can be made to change automatically to fit different system configurations. For

example, volume control and source selection can follow room combining.
