Thank you for purchasing the Yamaha ST15 Speaker Transformer.
This device is a matching transformer that is used for the parallel
connection of low impedance speakers to a high impedance type
distribution power amplifier.
Please read this manual carefully to get the most out of the ST15 and use
in a safe manner.
Outline
This device has a capacity of 15 W, the line output of the power
amplifier connected to the primary pole is assumed to be 100 V
(using a 70 V line is also possible).
The blue, yellow, orange and brown secondary cords each
correspond to speakers whose nominal impedance is 8, 6, 4 and 2Ω,
while the input impedance of the connected power amplifier is 670.
Connection
1. Turn the power switch OFF on the power amplifier you are
going to connect the ST15 to.
2. Use two 4 mm (1/8") tapping screws, securely attach the unit to
a speaker or some other convenient location.
3. Connect the ST15’s white primary cord to the power amplifier’s
100 V or 70 V negative (–) pole, connect the black cord to the
power amplifier’s 100 V or 70 V positive (+) pole.
4.
Connect the white secondary cord to the speaker’s negative (–)
pole. From the blue (8), yellow (6), orange (4) and brown
(2) cords, choose a cord that matches the speaker’s impedance
and connect the selected cord to speaker’s positive (+) pole.
5. Bundle together the unused secondary cords to prevent shot
circuits, etc.
Advanced Applications
Connecting Speakers of Different Impedance
An 8 speaker can be connected to the lower impenitence yellow
(6), orange (4) cords however, low impedance speakers
cannot be connected to higher impedance cords. The capacity will
be exceeded creating a hazard.
When connecting speakers of different impedance, refer to the
following chart. Please use caution when in such applications
since speaker input dB and the input impedance will change.
100 V Line Connections
70 V Line Connections
Limitations for Parallel Use
Depending upon the manner in which this device is used, the
connection of multiple speakers is possible however; the number
of speakers will be limited according to the power amplifier’s
specifications.
1. The total input for the speakers that are being used should not
exceed the power amplifier’s maximum output.
When the line output transformer is used, its capacity should
not be exceeded.
2. The total input impedance for the speakers that are being used
should not be less than the minimum load impedance of the
power amplifier, including the line output transformer.
The ST15 can be used in this manner as long as both conditions
1 and 2 are met.
