Specifications

AUDIO BUFFERING

256 samples (5.333 microseconds)

NETWORK

 

Protocol:

100 Mbps FAST Ethernet (FE)

Configuration:

Network repeaters OR switches

Audio Channel Capability:

64 channels maximum PER repeater LAN, scalable for network switches

Management Protocol:

SNMP (Simple Network Management Protocol)

Auxiliary Feature Support:

Serial data support of RS-232 bridged onto Ethernet

 

Device upgrade via TFTP

 

Device configuration via hardware interface OR software interface

Cable Type:

CAT-5 UTP (unshielded twisted pair)

Network Device Delay:

Class II repeater (network hub) <460 nanoseconds

 

CAT-5 UTP cable ~ 11 nanoseconds per linear meter (round trip)

 

Multimode fiber optic cable ~ 10 nanoseconds per linear meter (round trip)

 

Network switch : refer to CobraNet “store & forward” delay specification

Peak Audio and QSC provide support for audio networks built with repeaters, switches and media converters only. (QSC support is only available if the network uses QSC CobraNet products such as RAVE.)

Network products distributing CobraNet audio must meet specific timing requirements. Audio distribution via routers, gateways, protocol bridges, ATM, wireless transceivers, telecom or other WAN products is sometimes possible, but may prove unreliable and may require custom (contracted) support and some trial and error experimentation.

SYNCHRONIZATION

 

 

Master/Sync Output:

5 volts peak-to peak from 50 ohm BNC connector

Slave/Sync Input:

Use to synchronize network to an external clock source or Slave input for redundant operation

 

50 ohm BNC connecter

 

15 kHz. to 49.5 kHz. valid range of input frequency

 

To enable Sync: front panel hexadecimal switches must be set between 80 and FE hex or

 

 

configure via SNMP.

 

To use as Slave: connect to Master via coax cable Sync, then duplicate hexadecimal switch

 

 

settings (see pages 16 and 17).

MISC.

 

 

Chassis Power Connector Type:

IEC, fully filtered for RFI and EMI

Fuse:

 

2 ampere, 250 VAC, 20mm long X 5mm diameter, 2 required
