Hughes & Kettner Triplex - Manual (Page 6)

5.0 OPERATING THE TRIPLEX
5.1 SELECTING CHANNELS
Use the CHANNEL SELECT switch or an external footswitch
to change channels.
NOTE: Before using a footswitch, set the CHANNEL SELECT
switch on front panel of the amp itself to the CLEAN position.
5.2 THE TRIPLEX AND SIGNAL PROCESSORS
The effects loop on the TRIPLEX is a serial effects loop, meaning
that the entire preamp signal is routed
to the FX device and processed there.
TO CONNECT A SIGNAL PROCESSOR:
• Connect the processor‘s INPUT to the TRIPLEX LINE OUT jack
and the processor‘s OUTPUT to the TRIPLEX LINE IN jack.
• To avoid noise, signal degradation, and interrupted signals,
only use high-quality patch cables.
• Make sure the processor is not distorting the signal. Check
the processor's gain LEDs (if it is equipped with this type of
display) and use the input and output controls to dial in a
suitable level.
• Distortion devices are not designed for use in an FX loop. As
a rule of thumb, any kind of device that compresses the
signal should be connected first in the signal chain.
Depending on the type of effect you want to achieve, you
may want to connect your compressor directly between the
instrument and the amp's input.
• If you are using several processors or stomp boxes, ensure
you connect them in the proper order.
5.3 THE TRIPLEX AND MIXING CONSOLES
If you want to feed the TRIPLEX ' signal to a mixing console, we
recommend you route it through a Hughes & Kettner RED BOX.
Patch the signal from the LINE OUT jack, as this signal path's
level is not influenced by the MASTER setting. The RED BOX
balances the signal and simulates a speaker cabinet.
6.0 SERVICE AND PREVENTIVE
MAINTENANCE
The TRIPLEX does not require service of any type. However,
there are a few precautions you should heed to ensure your
amp lasts for many years.
• Ensure all peripheral devices, cords and cables are in a state
of good repair. Defective speaker cables are the most
common cause of power amp failure. Poor-quality cables
will cause hum and undesirable noise.
• Make certain your amp's ventilation ducts are not blocked
or covered. Proper cooling will prolong the life of your amp.
• Avoid mechanical shocks and exposure to extreme heat,
dust and especially moisture.
• When connecting peripheral devices, always pay close
attention to their specifications. Never connect devices with
high output signal levels (e.g. power amps) to your amp's
input.
• Ensure you have the correct AC power rating available
before you plug in the amp. If in doubt, ask the venue's
sound technician or the custodian of the building you are
rehearsing in.
