Introduction ~ G-Link Network

✍ A G-Link network will allow interconnection of up to eight

AP800s/AP400s and 16 AP10s.

G-Link Network

G-Link network architecture allows up to eight AP800s/AP400s and up to 16 AP10 Telephone Interfaces to be controlled as if all were part of a single unit.

Digital technology can provide a distinct advantage in designing and controlling teleconferencing systems. The ability to network with additional AP units (for a maximum of 64 mic inputs) makes the Audio Perfect systems ideal for room combining applications or larger applications which require more microphone inputs.

The G-Link gives you the ability to interconnect the AP800 with other Audio Perfect units (additional AP400s, AP10s, and AP800s). The maximum distance between connected ClearOne units is 20 feet/6.1 meters. ClearOne Communications recommends that category five twisted-pair (10Base) cable be used. Control of connected AP800s and AP10s is also possible via a single COM port.

When multiple AP800s ✍ are used in a system, the gating parameters on all

units must be set the same.

G-Link bus

This digital mix-minus bus appears on every Audio Perfect product. It allows audio to be routed to any destination on the G-Link network. The AP800 has four digital buses: X-bus, Y-bus, Z-bus, and G-Link EC Reference bus.

•X-bus.This mix-minus bus is defined as the master microphone mix, and it supports NOM (see page 24). All gated microphones are default routed to this bus.

•Y-bus.This mix-minus bus is defined as the line input master mix. All line- level audio such as from video codecs, AP400s, AP10 Telephone Interfaces, VCRs, etc. are default routed to this bus.

•Z-bus.This mix-minus bus is a user-defined auxiliary mix bus.

•G-Link EC Reference bus. This bus provides a system-wide echo canceller reference signal. It allows for the reference signal to be passed to additional G-Linked mic channels and their associated echo cancellers. Typically, one output on one unit will be passed along the G-Link EC Reference bus.
