Hughes & Kettner TrilogyTM Ultra Lead Channel, Master Section, Mains and Standby Switches

Trilogy™ Manual 1.1

1.4 Lead Channel

Articulate distorted tone plays a pivotal role in most players’ decision to buy an amp. A chief criterion for a top-notch guitar amp is its ability to retain the guitar’s character and deliver defined tone even with the GAIN knob cranked. Trilogy™ does this; what’s more, its LEAD sound is an excellent vehicle for classic rock leads and crashing power chords.

1.5 Ultra Lead Channel

Dive into a deep reservoir of distortion and let powerful sonic waves wash over you with every head-banging riff. The ULTRA GAIN channel delivers American-style high-gain tone with trouser leg-flapping low end and plenty of top-end slice. Hot and bad, this channel’s distorted tone is what the good doctor ordered for nu-metal and drop-D styles. It also serves up sumo-sized lead tone for all other genres.

Handling:

LEAD-GAIN:	Controls the amount distortion in
	the LEAD channel
ULTRA-LEAD-GAIN: Controls the amount distortion in
	the ULTRA LEAD channel
MASTER:	Controls the volume level
BASS:	Controls the amount of bass frequencies
	in both channels
MID:	Controls the amount of midrange fre-
	quencies in both channels
TREBLE:	Controls the amount of treble frequen-
	cies in both channels
LEAD ON:	Activates the LEAD channel (for a lean,
	mean classic British tone)
ULTRA LEAD ON:	Activates the ULTRA LEAD channel (for
	chunky American sounds)

1.6 Master Section

The master section lets you dial in Trilogy™’s overall output level, control presence, route effects and adjust the dry/wet balance, as well as “teach” the amp to respond to MIDI program change messages.

Handling:

FX-MIX, FX ON and SERIAL

SmartLoop™ is a special effects routing circuit offering a switchable parallel/serial effects loop. In parallel mode, (SERIAL is deactivated) the processed signal is added to the original signal of the preamp. Twist the FX-MIX knob to adjust the dry/wet balance, that is, the ratio of unprocessed to processed signal. Generally the best results are achieved by programming or setting the signal processor’s output to 100% so that only the wet effected signal and no dry signal is patched out of the effect device.

In serial mode (SERIAL is activated), SmartLoop™ works like a conventional serial effects loop. This means you must adjust the wet/dry balance on the signal processor.

Tip:

If you have not inserted an effect device into the FX loop, you can use this circuit for a variety of other purposes:

•In parallel mode, you can use the RETURN jack to connect a second instrument or any other audio source, and then blend its signal with the guitar signal using the FX MIX knob. You can also route the amp’s signal to a second power amp or through a RED BOX® to a mixing console.

•When in serial mode and bridged (SEND and RETURN jacks are connected using a cord equipped with 1/4" jack plugs), the effects loop can serve as a second master preset that may be activated for each channel via a footswitch. Use the FX-MIX knob to adjust the volume level.

xNote:

Be sure to connect a signal processor when the effects loop is configured in serial mode. Otherwise, the signal chain is interrupted and you will not hear your guitar’s signal!

PRESENCE

This knob determines the overtone content for all channels.

MASTER

As its name would indicate, this knob puts you in charge of the EL-34 power amp tubes and the100 watts of power they put out. Though this knob promises tons of tweaking fun, plea- se exercise restraint and caution.

MIDI LEARN

Assigns the given amp settings to a MIDI program number and serves to determine the amp’s basic MIDI configuration. For more on this, see section 4 – MIDI.

1.7 Mains and Standby Switches

MAINS ON/OFF

This button switches the main power supply on and tubes the opportunity to warm up for the work ahead.

STANDBY

This switch controls the high voltage power supply to the tubes. When engaged, anode voltage is applied to the tubes' filaments only so that the tubes remain warm and ready to rock. When taking a short break from playing, please use STANDBY rather than ON/OFF so the tubes remain at operating temperature.
