Appendix A
BRIDGING THE ARCHITECT
To increase the output power of the Architect, you can join
(bridge) two channels of the Architect into a single channel of 230
watts. Accomplishing this is a simple matter. Just press the Mono
button to send the same audio signal to both channels of the zone
and then connect the speaker terminals as shown in the diagram
below.
Appendix B
USING WITH ETHERNET-BASED AUTOMATION
SYSTEMS
The Ethernet LAN connection on the Model 961 enables
remote control of the amplifiers power and channel muting. While
the internal web server of the Model 961 provides an HTML web
page based interface, this is not the best means of controlling the
unit from another computer system. The Architect Model 961
provides a Telnet TCP/IP protocol for system programmers. The
Telnet protocol uses simple ASCII text commands to control and
monitor the Architect Model 961 amplifier.
To log into the Architect Model 961 via Telnet, you need a
Telnet client program in your system. The factory default static IP
address of the Model 961 is 192.168.0.1 and telnet is active on
port 23. The default user login ID and password are:
User ID: architect (note: all lower case)
Password: 900
An example of a typical telnet login session is:
/Telnet> login
/Telnet> UserID?: architect
/Telnet> Password?: 900
/Telnet> User authenticated!
/Telnet>
The serial ASCII control protocol over telnet allows simple
integration with other automation computer systems. The basic
command format is:
command<cr>
Where command is the ASCII text string of the command and
<cr> is an ASCII carriage return (0C hex) character as a com-
mand delimiter. These commands are case sensitive and have a
500mS timeout if no valid command or delimiter is sent.

Caution - Do not use a
speaker rated at less
than 8 ohms when
bridging. In a
bridged system, each channel of the
bridged pair “sees” one half of the
speaker load. This means that a
bridged amp driving an 8 ohm
speaker is actually operating into a
4 ohm load.
