GENERAL PRODUCT DESCRIPTION
T560-71/T5100-71
70.7 / 100V
Transformers
Altec Lansing is renowned for its high quality transformers.
The new Altec Lansing Professional transformers, T560-71
and T5100-71, are perfect complements to our premium
Duplex® Speakers when the prerequisite is high fidelity.
These transformers are designed for 70.7V or 100V distribution
of amplifier power, with minimal loss, to multiple loudspeakers.
True electrical isolation is provided to the source and the load
by the primary and secondary windings respectively. Installation
is simple with 0.25-inch blade type wire terminals, allowing
either solder connections or crimp type quick-connect wire
terminals.

ARCHITECTS & ENGINEERS SPECIFICATION
The transformers shall be Altec Lansing Professional model numbers T560-71 and T5100-71, rated at 60 Watts and 100 Watts, respectively.
Their frequency response shall be 35 Hz to 15,000 Hz, ±0.5 dB. Throughout their 35 Hz to 15,000 Hz bandwidth, at rated power, they shall
produce no more than 0.5% T.H.D., and their insertion loss shall not exceed 1 dB. These transformers shall require no more than 10%
above their rated input power to deliver rated power to the load at 35 Hz. The T560-71 and T5100-71 shall provide true electrical
isolation to the source and to the load. Connection to these transformers shall be through 0.25-inch blade type wire terminals. The
nominal primary taps shall be 4 ohm and 8 ohm, and the nominal secondary taps shall be 70.7V and 100V.round white metal grille.E
