Note on specifications: Summit Audio is  uncompromisingly committed to excellence. All
of our specifications are made with the latest technology and are UNWEIGHTED
measurements. What does this mean? When measurements are “weighted” (e.g. “A”
weighted, dB (B), dB C weighted, etc.), the measurement devices are basically EQed or
filtered before the measurement is taken. This filtering was developed so that sound
pressure level (SPL) measurements can more nearly match human’s non-linear hearing
characteristics. However, when used in noise, frequency response, and distortion
measurements, weighting will alter the results. Completely flat frequency measurements
are key to giving accurate specifications. Summit Audio devices are the highest quality
professional audio gear and the specifications below are made with the flattest possible
unweighted measurements, giving the most accurate results.

To operate this unit on 115 volts, unplug the unit, switch the line voltage selector on the
back of the unit to read 115 volts and confirm that the external fuse (mounted in chassis)
is a [3 AG ½ Amp slow blow]. To operate this unit on 230 volts, switch the line voltage
selector on the back of the unit to read 230 volts and confirm that the external fuse
(mounted in chassis) is a [3 AG ¼ Amp slow blow].
