Speaker selectors are electronic devices used for distributing sounds over an entire room or house. They accept receiver outputs and allow connection to one or more additional pairs of speakers for remote placements in the house. They have built-in amplifier protection that provides constant impedance load to amplifiers especially when the receiver suffers from impedance drop.
Some speaker selectors are built with volume controls that allow the user to adjust the volume of each additional pair.
Types of Speaker Selectors
Kinds of Speaker Selectors include the following:
Resistor-based speaker selectors
Resistor-based speaker selectors are designed for background music applications. They are generally efficient and low cost. They can have dual source switching capabilities.
Most resistor-based speaker selectors are equipped with wiring connection harness systems. Most models can also connect up to eight speaker pairs.
Autoformer-based speaker selectors
Autoformer-based speaker selectors are ideal for die-hard audiophiles. They are more efficient than resistor-based models. They provide enhanced highs and lows in various sound levels.
These speaker selectors can have independent channel grounds compatible with all amplifiers. Most models feature multiple-position volume control and can connect up to 12 speaker pairs.
Choosing Speaker Selectors (Buying tips)
Compatibility: Get a speaker selector compatible with your speakers and speaker system. Expensive speakers usually require autoformer-based selectors, while cheaper ones usually work with resistor-based models.
Accommodation: Choose a speaker selector than can accommodate the number of speakers you intend to use. Get a standard speaker selector if you have four speaker pairs. If you have up to 12 speaker pairs in the house, look for a more advanced (usually expensive) model.
