The Channels of the Edition Blue DFX
The Effects of the Edition Blue DFX
The Edition Blue DFX is equipped with two channels, Clean and Lead. Its innovative circuit design, which simulates the important sound-forming elements of tube amps using semiconductor technique, gives both channels the dynamics needed by a discerning guitarist for his/her musical expression. The sensitive preamp of the Edition Blue DFX not only produces harmonious overdrive but also a significant dynamic response to the style of playing.
The Edition Blue DFX is equipped with two independent signal processors. Signal processor 1: modulation effects and Delay, Signal processor 2: digital spring reverb. Both signal processors can be used at the same time and are independently adjustable. The settings work for both the Clean and the Lead channel.
The first effect section of the Edition Blue DFX offers you the two most important modulation effects, Chorus und Flanger, as well as Delay. They are behind each other on the Preset Adjust control. In the first section, the Chorus is active; in the second section, the Flanger is active and in the third section, the Delay. Within a section, you can change the character of the effects with this potentiometer. The parameters are selected in such a way that it creates good quality sounds which Lead quickly and simply to the desired effect. Through clockwise rotation, the speed (rate) of the modulation effect changes. Dependent on the rate, the modulations depth is automatically regulated in such a way that in every control position the best possible sound effects are always heard. With Delay, the Delay (time) and the number of repetitions (Feedback) change at the same time. The mixing ration between dry signal and the effects can be infinitely variedly regulated with FX Level.

1.1 The Clean channel

Depending of the preamp control settings, the amp can produce a variety of contemporary and vintage Clean sounds.

Determines the Clean channels Volume. Depending on the type of pick-ups, the amp will begin to clip somewhere around the 12 oclock setting. If desired, the Clean channel can produce a lot of crunch.
This Channel Selector switch activates either the Clean or Lead channel. The Lead channel is active when the button is pressed.

1.4 The Lead channel

Classical, open rock sounds direct and dynamic. In particular the effective sound-shaping tool facilitates a large spectrum of Lead sounds.
With slow adjustments, the Chorus sounds deep and rich, which works best for floating ballads. Thanks to the automatic effect depth adjustment, quicker Chorus adjustments dont scream.
Controls the amount of distortion in the Lead channel.

1.6 Lead Master

Determines the Lead channel Volume Level in relation to the Clean channel Volume Level.
The slow Flanger settings give an intense sweeping effect, while with rapid adjustments you can produce current rock and pop effects.
The sound control works for both channels. Mid and Treble controls influence each other (as is also standard and desired on tube amp models): if you boost the treble, it causes a central lowering and vice versa. This characteristic enables the greatest possible variety of sound nuances.
With the Delay control, the time to the next repetition can be varied infinitively from 80 ms to 1400 ms. Feedback is automatically adjusted. Short Delays with little feedback are best suited for rockabilly sounds, intermediary Delays are perfect for typical U2 sounds, while long times are good for playing the canon-like Queen licks.
Controls the Master Volume of the Edition Blue DFX inclusive of the effects. The Line Out signal remains unaffected by this control.
This control determines how many Chorus/Flanger/Delays should be mixed with the sound. At the left control the signal is dry, effect section one more or less switched off. At the right control, a mixing ratio of 1:1 exists. The FX Level control works independently of the Reverb control. Only for Edition 30 and 60 DFX: the FX section can be switched on and off with the Footswitch. As with the FX Level control, Reverb works independently. See also 3.3 Footswitch.
The Reverb is an authentic adaptation of a classic string Reverberation. It works and responds in exactly the same way: the control Reverb adjusts the Volume of the string Reverberation while the time always stays the same. The Reverb control works independently of the FX Level control. In the same way, when the left control is used, the signal is dry and effect section two is more or less switched off.

To connect a signal processor:
Connect the processors Input to the Line In jack and the
Output to the Line Out jack.
To avoid noise, signal degradation, and interrupted signals,
only use high-quality patch cables.
Always make sure that the signal processor is not distorting
the signal. If necessary also observe the Volume indicator of the signal processor and use the Input and Output control of the signal processor for dialing in a suitable Level.
Outlets and other Controls
Distortion devices are not designed for use in an FX loop. Generally,
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 amps Input.
If you are using several processors or stamp boxes, ensure you
connect them in the proper order. If you want to feed the Edition Blue DFX signal to a mixing console, we recommend you route it through the Hughes & Kettner Red Box. Patch the signal from the Line Out jack, as this signal paths Level is here. The signal is then independent, balanced and frequency corrected (speaker simulation) from the Master control.
3.3 Footswitch (not applicable for Edition Blue 15 DFX)
This jack is for a standard 1-way or 2-way Footswitch (e.g. Hughes & Kettner FS-1 or FS-2). This allows you to switch back and forth between the Clean and Lead channels and to turn the effect section on and off as you want. If you use a 1-way switch, the channels are switched; if you use a 2-way switch, the channels run through switch 1 and the effects are controlled by switch 2. english
If you want to be able to control the channels by the Footswitch, the Channel Select switch must be switched to the front of the Clean channel.
Headphone jack. The speaker is automatically switched off when a plug is inserted into this jack.

3.5 CD Input 3.1 Input

Connecting socket for guitar Jack for connecting CD players, tape decks or other audio sources. The circuit is controlled directly by the Master circuit of the Edition Blue DFX, which means that you can use the Master control to adjust the Input signals volume. To dial in the desired balance of levels for the playback and guitar signals, the connected playback device has to be equipped with some type of variable Output control. Most audio sources have an adjustable headphone Output. You can connect this with the CD Input with an appropriate adapter (stereo As soon as the Line Out jack is occupied, the internal signal path is interrupted in order to feed the external signal. If no external signal processor is used, this jack must stay free. It cannot be used as an additional Input. jack/2 x cinch).

3.2 Line Out and Line In (not for Edition Blue 15 DFX)
The Edition Blue DFX is equipped with a serial insert. The preamp signal of the amp is completely routed and processed through an ingrained signal processor. The Line Out can also be used as the Output for a mixing console.
Jack for the included Mains cable. Ensure the amps voltage matches your local AC voltage rating before you plug the cord into the wall socket. 9
Before you switch on the audio playback device, turn the Master control all the way down. Then turn up the Master control a little and dial in the desired balance levels. Once youre satisfied with these levels, gradually turn up the control to the desired overall level.
The Edition Blue DFX will not switch on:
The amp is not receiving any Mains voltage. Check the Mains cable
to see if it is properly connected.
Standard Setup and Cable Connections
The Mains fuse is defective. Replace the fuse with another suitable
fuse. If this fuse is also defective, consult your Hughes & Kettner dealer. The Edition Blue DFX is correctly connected but the sound is inaudible:
One or more of the Gain and Master controls may be turned down. One of the internal fuses is defective. Get a qualified service
technician to replace the fuse (taking care that the values are the same) The Clean channel cannot be activated through an external Footswitch:
The Channel Select switch on the front panel may not be in the off
position. Switch the Clean channel on. When using the Line In / Line Out jacks, there is a humming noise:
An electrical or magnetic field is causing interference. Here, it is
recommended to use a DI box, e.g. Hughes & Kettner Red Box.

Service and Maintenance

You have connected an FX processor to the Line Out jack but the signal is totally distorted even when using Clean sounds.
The Edition Blue DFX amps do not require maintenance of any type. However, there are a few precautions to observe to significantly lengthen the life of your amp:
The Input of the FX processor is overloaded. Reduce the processors
Input sensitivity (Input or Gain). You have connected an FX processor to the Line Out but the
Always ensure that all peripheral devices, cords and cables are in

a state of good repair! Defective speaker cables (short circuits, loose connections) are the most common cause of failure. Poor-quality cables will always lead to humming problems.
Output signal is too quiet:
The FX processors Output Level is set incorrectly. Turn the Output
Level of the processor up high.
Make sure that your amps ventilation ducts are not blocked

or covered.

Avoid mechanical shocks and exposure to extreme heat, dust and

especially moisture.

Pay close attention to the specifications of peripheral devices. Never connect devices with high Output signal levels (e.g. power
amps) to your amps Input.
Check for the correct voltage before you plug in the amp. If in
doubt, check with the venues sound technician or the caretaker of the building.
Do not carry out do it yourself repairs. Get a qualified service
technician to replace internal fuses.
Use a soft, damp cloth to clean the exterior surface of the
