NOTE:
In any speaker installation, the total RMS speaker load (the sum of all
power to all speakers) must not exceed 500
watts per channel. It is strongly
recommended that “Efficient” extension speakers be used.
3 When you have reached a satisfactory combination of speakers and speaker power
consumption, connect the T1 to T7 speakers and the 70V sp to -. Then use the
“Connections”
column as a guide to wire the tapped T1 through T6 speakers.
Amplifier Overload Check
Check that the amplifier is not overloaded by performing the following four steps:
1. Make sure that the extension speakers are connected to the audio output transformer
terminals properly (E1 through E7, and A1, A2) or (T1 through T7 and CH1 + - and CH2 + -).
2. While music is playing, if the yellow CLIP LEDs
on the amplifier stay OFF or flicker in a
random manner, the load is acceptable.
3. If one or both yellow CLIP LEDs
is always lit or flickers continuously, the amplifier is
overloaded and will shut down, and you must perform Step 4.
If a red OVERLOAD LED on the amplifier flickers, the amplifier is overloaded and will shut
down. You must perform Step 4 below.
4. Do this step only if a CLIP or OVERLOAD LED came on as described in Step 3. Find the
source of the overload (shorted speaker wires, too many speakers connected, or speaker
power taps too high in total wattage). After you fix the short, disconnect a few speakers or
lower the speaker power tap selection to reduce the wattage, then repeat Step 2.
