Your MASTER SERIES speaker selector uses high power transformers with selectable taps which allow you
to obtain maximum power transfer while maintaining a safe load of 4 Ohms or higher on the driving amplifier,
regardless of the number of speakers in use at the time. A six position rotary switch is provided on the bottom of the
unit, accessible with a blade type screw driver inserted through the access hole. This permits selection of the
appropriate tap. Note that there is no significant power loss with transformer matching. When optimally set, there will
be a level drop, but the full amplifier power output will be available, divided equally among speakers in operation.
This system is capable of transforming a 1/3 Ohm load to appear as a 4 Ohm load to the amplifier, which is
equivalent to 12-4 Ohm or 24-8 Ohm speakers operating simultaneously. Thus it is apparent that many more
speakers can be used than the number of ON-OFF switches (6-12) suggest. Some switches can be used to control
individual speaker pairs, while others may be used to control "zones" consisting of several pairs on the same switch.
The impedance matching transformers are rated for continuous operation at 250 Watts RMS (750 Watts
music power). They are connected so that the right and left channels are completely isolated electrically. Wiring of the
switch box is to screw terminals on the rear panel, which can accommodate wire up to 10 gauge, more than adequate
for most installations.
The optional SONIC STABILIZER and IMPEDANCE INDICATING SYSTEM do not require any different
connections; the following information is applicable to all model variations. Information about these special features
follows the installation instructions.
Prepare your wire leads by stripping about 1/4" of insulation off each of the wire ends. Twist strands tightly
together so that none stick out to cause possible short circuits. Wire the unit following the diagram on the following
page. OBSERVE POLARITY! (Note that the INPUT connector block is green and the OUTPUT connector blocks are
black).
If connecting several pairs of speakers in a "zone" configuration, best results will be obtained with all of them
connected in parallel. Series arrangements can be used, but usually with some sacrifice in sound quality.
Your MASTER SERIES speaker selector can be placed anywhere there is space for it. No special precautions
are necessary because no significant amount of heat is generated in normal operation.
The rotary IMPEDANCE MATCH switch (accessible from the chassis bottom) is used to make connection to
the appropriate impedance matching tap on the transformers. The markings around the hole show the attenuation of
level for each position. As the attenuation is increased (CCW rotation of the shaft), the number of speakers that can
be operated simultaneously also increases. Matching impedance for each switch setting are shown below (for a 4 Ohm
load to appear on the amplifier output). The first number indicates the level drop in decibels, as marked on the
switch access opening, followed by the number of speakers that can be operated at that setting.
