HTD Basic Whole-House Audio System
HTD Speakers in use
basic system review
When you don't need every zone to select its own audio source, extending audio from a central source throughout your home is easy. All you need is a multi-channel or 2-channel (stereo) amplifier, primarily depending on the number of zones you need, and a volume control in each zone. Each volume control can control one pair or multiple pairs (up to 8) of speakers.

4-conductor speaker cable is run from the amplifier to each volume control. 2-conductor speaker cable is run from each volume control to each of the speakers in that zone.

2-Channel Basic Setup

A multi-source, 2-channel (stereo) amplifier is combined with 1-4 volume controls. This is often the best solution when you have four or fewer zones. Works great with, or without, an existing home audio receiver.

Multi-Channel Basic Setup

A 12-channel amplifier is combined with volume controls in each room. Suitable for any combination of up to 6 stereo or 12 mono zones, with enough power for up to 24 8-ohm speakers. This is often the best solution for extending an existing home audio receiver into addtional rooms.
