Speaker Connections for CT Receiver
The CT Receiver connects to speakers using 4 position plug-in Phoenix connectors. Speaker wires are all
home run from each zone to the back panel of the CT Receiver. Unplug the connector from the rear of the
receiver, strip the speaker wire approximately ¼" and insert the bare end into the gate on the connector. Use
a small flat blade screwdriver to tighten the
connection to each conductor. Connectors
accommodate up to 12-gauge wire.
Make sure to observe polarity as you
hold the connector upside down to con-
nect Left and Right as shown. Two
guide tabs also insure proper orienta-
tion.
Speaker Connections CT310 / 300
The CT310/300 Zone B and Zone C connectors termi-
nate using the 4 position plug-in Phoenix connector.
CT310 Zone A speakers can be connected either via the
same plug-in Phoenix connector or via 5 way binding
posts for premium speaker wire. The CT310 Zone A
amplifier is 150 watts per channel, CT300 Zone A ampli-
fier is 55 wats per channel. The CT300 does not include
binding posts.
AC Power and Line Fuse
Before connecting any cables, verify that the CT Receiver powers up. Check functionality of the receiver by
connecting the AC power cord and powering on the receiver with the main power button. When the front
panel display lights up, power the system down once it has finished the boot up process. Disconnect the AC
power cord at the rear of the CT Receiver for safety. You can re-connect once the system connections are
complete.
If you need to check the fuse, follow this procedure:
1. Power off the unit and unplug the power cord.
2. Push up on the fuse release tab.
3. Pull the entire fuse holder out.
4. Remove the fuse from the fuse holder and measure the fuse
with a meter. You cannot tell if it is blown by looking at it.
5. Replace only with fuse of same value. CT Receivers use
12A Slow-Blow fuses for main A/C.
Caution! A blown fuse is usually an indicator of an installation or serv-
ice problem. If fuses continue to blow, call B&K Components
Customer Service at 716-656-0026 or contact an Authorized B&K
Service Center for assistance.
