Power Button
Press the Power button once to turn the Model 5125 on, press it again to turn it off. The Power
button is inoperative when the Auto Turn On switch is set to Audio or 12V.
Protect Indicator
The Protect indicator will illuminate red if the Model 5125 experiences an external fault condi-
tion and the unit will stop playing. This prevents possible damage to the unit from continued
operation. Examples of external fault conditions are short circuited speaker wires, excessive
heat, and trying to drive too many speakers at high levels.
If Protect is illuminated you need to locate and correct the fault; for example, remove the short
circuit, let the unit cool down, check the load impedance and lower the volume level. To reset
the protection circuit you need to turn the unit off.
Turning it off:
•
Auto Turn On switch (on the rear panel) in the Man position: press the Power button on the
front panel.
•
Auto Turn On switch in the 12V position: turn off the 12V trigger source; the 5125 will turn
itself off right away. You can also turn it off by unplugging its AC power cord.
•
Auto Turn On switch in the Audio position: turn off the preamplifier, surround controller or sys-
tem controller that drives your 5125. You can also unplug the 5125’s AC power cord.
Note: It requires approximately 15 minutes after removing the audio source before the 5125
turns itself off. If you don’t want to wait and you have access to its AC cord, simply unplug it.
Leave it off and/or unplugged for awhile to cool down and you’re confident the fault is correct-
ed. If you unplugged its AC power cord to turn it off, plug it in again.
Hi-Temp Indicator
Hi-Temp will illuminate red when the Model 5125 exceeds its maximum safe operating tem-
perature. If the heat persists, the unit will activate its protection circuit and stop playing. It will
remain in this protection mode until the temperature drops and the unit is turned off to reset
its protection circuit. Use the same turn-off procedure as above. If Hi-Temp appears, it’s likely
the unit is been over-driven at too high a listening level or is attempting to drive a speaker load
impedance that is too low. It’s probable the unit has not been provided with sufficient ventila-
tion. These conditions must be corrected before turning it on again to resume operation.
Channel 1 2 3 4 5 Status Indicators
1 2 3 4 5 will illuminate green when the Model 5125 power is on and it is operating nor-
mally. The 1 indicator will not light if a fault is only in channel 1; the 2 indicator will not light if a
fault is only in channel 2, and so on. None of the five indicators will illuminate if there is a gen-
eral fault or if the temperature is too high.
