Whole-House Audio Control Owner’s Manual
Introduction to the MC-66 & MCA-66 Whole-House Audio Control System
The MC-66 is a six source, six zone stereo audio controller that easily allows you to distribute sound throughout
your home. The MCA-66 includes these same features plus a built-in 12-channel amplier. Both units are controlled
by the keypad(s) located within each zone and/or with HTD’s Valet app on iPhone and Android devices.
With the MC-66 & MCA-66, each of the six zones independently selects from up to six centrally located sources.
This means each zone can play a completely different source. Also, from any keypad, you can easily turn on
all zones to the same source. We refer to this as “party mode”. You can also turn off all zones with the press of
a single button. Tone control (bass/treble) and balance allows each zone to be independently set for the best
sound in that zone. We have also developed the Valet Home Control app (for iPhone and Android devices) which
expands this functionality providing wireless control.
The controller, keypads and Valet Home Control app have been designed to make both installation and every-day
use intuitive and user friendly.
If, after reading this manual, you have any questions, please call us toll free at 1-866-483-2834 during business
hours (M-F 8am-6pm CST). We’re here to help and to make sure you are getting the most out of your new wholehouse audio system.
IMPORTANT WARNINGS AND HELPFUL TIPS
Please note that while we refer to Cat5e throughout this manual, Cat5 and Cat6 can also be used with
equal effectiveness.
1. Never connect or disconnect Cat5e cable from the keypad or controller while the controller is
powered on.
2. Never connect or disconnect speaker cable from a speaker or the controller while the
controller is powered on.
3. ONLY TERMINATE CAT5e CABLES WITH RJ-45 CONNECTORS USING THE 568-A OR
568-B STANDARD (see page 17). You cannot simply connect the 8 wires in the same order
at both ends. Cat5e cable consists of 4 twisted pairs of cable and some signals are sent down
a particular twisted pair in order to prevent cross-talk. Failure to follow one of the standards will
cause the system to act erratically or be entirely inoperable.
Note: Because 568-B is the more recent standard, we encourage you to use it instead of
568-A.
4. When connecting (daisy-chaining) more than one keypad into the SAME zone, each keypad
must also have a unique combination of shorting bars installed. Each keypad includes 2 shorting
bars already installed - this represents one of the four possible combinations. Removing only the
left shorting bar is a second combination; removing only the right is a third; and removing both
shorting bars is a fourth combination.
