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
