The DLS Speaker Switch (#300-606) enables you to play up to four pairs
of speakers throughout your home. Play one pair, any combination of
pairs, or all pairs at once.
The output from the receiver is wired directly to the 300-606. From there,
speaker wire is run to speakers located in four locations throughout the
house such as the family room, living room, dining room, kitchen, or
master bedroom. Music for each location is selected by pressing the
corresponding button on the switch. A room sticker sheet is included for
easy identification of areas equipped with speakers.
Features:
•
Connects up to four pairs of speakers.
•
Built-in resistor protection circuit safeguards your receiver or amplifier.
•
Separate left and right channel ground paths for compatibility with all
amps even bridged.
•
Pushbutton spring loaded terminals accept up to 14 gauge
speaker wire.
•
Power handling 100 watts RMS/channel.
•
May be used with 4,6,or 8 ohm speakers
•
Ideal for both home and commercial applications.
Amplifier Impedance Load
Most pairs of speakers are connected to the amplifier in parallel, as more
pairs of speakers are added the overall impedance becomes lower. For
example if two pairs of 8 ohm speakers are connected in parallel the
impedance will be 4 ohms; two pairs of 4 ohm speakers become 2 ohm.
Most receivers or amplifiers are not rated for use below a 4 ohm load and
it is not recommended to connect more than two pairs of speakers without
using some form of impedance protection.
The DLS Speaker Switch includes impedance correction circuitry that
protects the receiver or amplifier from low impedance loads. The circuitry
assures that your receiver or amplifier will see a safe operating load, even
when all four speaker pairs are playing at the same time.
Impedance Correction
This process insures that the impedance load shown to the receiver never
goes below the rated capability of the equipment. See the charts below
for specific impedance loads that will be presented to your receiver
depending on the number of pairs and the impedance of the speakers that
you are using.
