ClearOne AP800 - Manual (Page 10)

Introduction ~ G-Link Network 6

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.
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.
G-Link Network
A G-Link network will
allow interconnection of
up to eight
AP800s/AP400s and 16 AP10s.
✍
When multiple AP800s
are used in a system, the
gating parameters on all
units must be set the same.
