QSC Audio S series 사용자 설명서

A RAVE network routes audio signals in bundles of up to 8 channels. Behind the removable cover on the front panel are two

pair of hexadecimal switches for assigning bundles to the 8-channel audio groups. Note that the following discussion only

applies to front panel configuration of RAVE devices (stand-alone or “hardware” mode).

-For RAVE 80 and 160: These are outputs, or the channels “received” off of the network

-For RAVE 81, 88, 161 and 188, these are input, or the channels “transmitting” onto the network

-For the RAVE 80/81/160/161, the right pair of switches apply routing to channels 9 through 16.

-For the RAVE 80/160, these are audio outputs.

- For the RAVE 81/161, these are audio inputs to be transmitted on the network.

- For the RAVE 88/188, the right pair of switches apply routing to channels 1-8.

To make a RAVE unit receive a bundle of CobraNet audio channels from a transmitting unit, set the receive unit’s bundle

switches to the same hex value as the transmitter.

When all front panel hexadecimal switches are set to “FFFF”, the RAVE unit enters a utility mode. This mode can be useful

when reprogramming a RAVE or in disabling the software mode of operation.

Reprogramming through the RS-232 connection has given way to the network method, which uses TFTP (trivial file transfer

protocol) over the Ethernet connection. The TFTP method creates the least amount of network disruption and provides the

simplest implementation.

Since a RAVE may be configured via SNMP and retain its parameter settings, it is possible that a unit may arrive at an

installation site where no method of interacting with the device through the software interface is possible. If a unit arrives

in this “write” mode, the front panel hexadecimal switches will only affect the device I.D. No bundle or configuration setup

is possible through the switch interface in this mode.  Setting all front panel hexadecimal switches to “FFFF” and resetting

(power cycling) the unit will provide a type of “software kill”. The front panel switches can then be set to the desired

bundle assignments and a second device reset will again implement hardware control.
