buttons [C], you can select it with the Enter button [B] to modify it. Then,

you can step out of the menu with the Esc button.

E. LED meter. This assignable, peak-level LED bar meter is used to display

the audio level of an input, output, or processing channel of the XAP 800.

A. Power. This power module accommodates power ranging from

100–240VAC, 50/60Hz. The module uses an IEC-type connector. No

switching is required.

B. Inputs 1–8. These Phoenix block connectors are for connection of eight

mic-level or line-level (selectable) inputs. These connectors are typically used

for mics, but can be configured for use with VCRs, CD players, XAP TH2,

etc. These inputs can be mixed in any gated or non-gated combination and

routed to any of the 12 outputs. Default input level is -55dBu. For more

information about input adjustments, see page 32. For electrical

specifications, see Appendix A: Specifications.

C. RS-485 Remote Panel A/B Port. These four-pin Phoenix connector ports

allow you to control the XAP 800 with the ClearOne Control Panel or XAP

IR Remote Control.

Figure 1.3. Rear panel connections

Introduction ~ Controls and Connections

Power is supplied through the RS-485 ports to the remote Control Panels

from the XAP 800. This power is limited to a total of 300mA at 15 volts

for each connector. Over-current protection is provided on the +15V pins to

prevent damage in the event of shorting. External power can be provided to

control devices when more current is required. See page 92 for maximum

cable run distances when using ClearOne Control Panels.

D. Control/Status Ports A and B. These two female DB25 connector are used

to connect control devices to the XAP 800. The control devices have access

to the command set for the XAP 800 and can be used for common functions

such as volume control, muting, preset change, room combining, etc. Devices

can be connected to either port.

For instructions on how to program the control and status pins, see the

GPIO section on page 77. The default settings allow control and status of

inputs, outputs, volume, and presets. These pins are active low. The 32

presets can also be activated via these connectors. For pinout and default

information, see Appendix B.

E. Outputs 1–12. These three-pin Phoenix connectors are for connection of

twelve line-level balanced outputs with three-pin Phoenix connectors. These

outputs are typically used for connection to VCRs, tape recorders,

amplifiers, codecs, phone hybrids, and other audio devices. These outputs

may be configured to contain any combination of gated and non-gated

inputs. The nominal output level is 0dBm.

F. Inputs 9–12. These Phoenix connectors are for connection of up to four

line-level inputs. These are typically used for connection of VCRs, tape

players, CD players, and other audio sources. They can be routed to any

output or multiple outputs. Nominal level is 0dBu.

G. Expansion Bus In/Out. This RJ-45 connector is part of the expansion bus

(E-bus), which allows up to eight XAP 800 or XAP 400 units and up to 16

XAP TH2 units to be networked together. The E-bus consists of two buses:

one for control, the other for passing audio and mic information (see Control

bus, page 7). Using Cat 5 twisted-pair cable, you can separate adjoining

units up to 80 feet (24 meters). See the diagram on page 11.

I. RS-232. This female DB9 serial port is for interconnection between the

XAP 800 and a PC, modem, or other custom remote controller. For serial

protocol, see Appendix B: Connector Pinouts.

Introduction ~ Networking

Networking

The latency or propagation

delay is <1ms.

✍

Expansion bus

The digital mix-minus expansion bus (RJ-45 LAN) is used to connect up to eight

XAP 800/400s and 16 XAP TH2 units, where the total number of microphone inputs

does not exceed 64. The maximum distance between interconnected XAP 800/400 or

PSR1212 units is 80 feet (24 meters). Connecting a XAP TH2 must not increase the

cable length between two PSR1212s, XAP 800s and/or XAP 400s beyond 80 feet.

ClearOne recommends that category five twisted-pair (10BaseT LAN) cable be used.

The expansion bus (E-bus) allows audio routing between destinations on the

E-bus network. The E-bus contains 12 independent digital audio buses labeled O–Z

which can route mic or line level inputs in any combination across the E-bus

network. The O–Z buses are divided into two groups (O–R and S–Z) based on their

capabilities and default settings. The E-bus also contains four PA adapt/acoustic

echo cancellation reference buses, four global gating buses, and one control bus.

•O–R buses. These four audio buses are defaulted as the mic mix buses; they

can communicate the NOM count and mic mixing parameters across the

network to other XAP 800s. All gated mics are routed to the 0 bus by default.

•S–Z buses. These eight buses are defaulted as auxiliary mix buses. They are

used to route auxiliary audio, such as from a CD player or VCR, to and from

other units on the network. These buses are also used as mic mix buses when

NOM count is not required.

•PA Adapt/Acoustic Echo Cancellation Reference buses. These buses

allow an input from a XAP 800 to reference an output on another linked

XAP 400/800. See PA Adapt and AEC Reference on page 33 for more

information.

•Global Gating Groups A–D buses. These mix-minus buses are defined as

microphone gating groups which support first-mic priority, maximum

number of mics, etc. and work across all linked XAP 400/800s. Unlike the

audio buses, they contain only mic status and gate parameters. See page 41

for more information about gating groups.

•Control bus. The control bus is an independent channel from the E-bus’s

audio channel; it uses a different pair of wires on the same E-bus cable. This

allows control information to pass even if the units are not using the audio

link. The XAP 800 supports the full set of commands through the control bus.
