Hughes & Kettner manual Troubleshooting, Triplex will not switch on

Page 7

Refrain from do-it-yourself repairs! Have a qualified service technician replace internal fuses.

With the unit off and unplugged, use a soft damp cloth to clean the exterior surface of the TRIPLEX.

7.0TROUBLESHOOTING

1)The TRIPLEX will not switch on:

The amp is not getting any AC power. Check the mains cable to see if it is connected properly.

The mains fuse is defective. Replace the fuse with another identical fuse. If this fuse also trips, consult your Hughes & Kettner dealer.

2)The TRIPLEX is connected properly, but no sound is audible.

One or several GAIN and MASTER controls may be turned all the way down. Dial in a higher setting.

A short circuit in the speaker signal chain may have tripped an internal fuse. Make sure none of the connections are shorted out and have a qualified service technician replace the fuse (identical specifications are a must).

3)The footswitch does not switch channels:

The front panel selector switch may be in the OVERDRIVE position. Set it to CLEAN (in this case, CLEAN = off).

The footswitch is not connected to the TRIPLEX. Plug it into the appropriate jack.

4)When accessed, the LINE OUT/LINE IN jacks cause annoying hum.

An electrical or magnetic field is causing interference. Use higher-quality cables or re-arrange the cables you are using to reduce interference to a minimum. If this still doesn't improve the situation, use a DI box.

The grounding of the connected devices may be causing a ground loop. DO NOT SEVER THE GROUND OF THE CONNECTED DEVICES UNDER ANY CIRCUMSTANCES! Try plugging all devices into the same socket via an AC power distributor/power strip. If this doesn't eliminate the noise, you must ensure the connection is galvanically separated by routing the signal through a DI box.

5)You have connected an FX processor to the LINE OUT jack and the signal is totally distorted, even when you have dialed in a clean sound.

The LINE OUT signal is overloading the input of the FX processor. Reduce the processor‘s input sensitivity ("INPUT" or "GAIN").

6)You have connected an FX processor to the LINE OUT jack of the TRIPLEX and the signal's volume level is way too low.

The FX processor's output level is set incorrectly. Turn it up.
