EDITION BLUE 60-R-MANUAL

CONGRATULATIONS AND THANK YOU
FOR CHOOSING THE HUGHES & KETTNER
EDITION BLUE 60-R AMP!

- Check that the local current and the amp's AC power
rating are identical before you plug the power cord
into an AC outlet.

- Ensure that air can circulate freely around your amp's
ventilation ducts.

- Place the amp on a stable platform where it is not
exposed to mechanical shocks and temperature
extremes which may damage the amp or endanger
the safety of bystanders.

- Hughes & Kettner is not liable for damages due to
improper use.

A team of guitarists and technicians developed the
EDITION BLUE 60-R amps with a single purpose in mind:
To provide you with sophisticated guitar sounds and
practical features in an easy-to-handle package.

The EDITION BLUE 60-R is the ideal workhorse for discer­ning players who want happening tone in a compact
amp. The EDITION BLUE 60-R's high-performance Current
Feedback power amp delivers not only 60 watts of
punch, but also the sought-after tone of a classic tube
amp.
One component playing a major role in the overall tone
of the amp is the RockDriver Junior speaker. Custom­made for Hughes & Kettner to our specifications, this
speaker not only perfectly captures the essence of
vintage sound, but also is extremely efficient. This makes
your EDITION BLUE 60-R substantially louder than other
amplifiers having the same output power rating.
As very special treat, the EDITION BLUE 60-R offers the
option of connecting a CD player or tape deck. This
handy add-on feature allows you to play along with
CDs or playback tracks of your own making for rehear­sals, jamming, or even one-man/woman gigs.
The EDITION BLUE 60-R has the versatility, sound, and
features that inspires you to perform your best in smaller
venues, rehearsal rooms and studios.
Its logical control layout gives you immediate access to
the EDITION BLUE 60-R's world of sound. This manual
introduces you to its many features and application
options.

1.0 CHANNELS

The EDITION BLUE 60-R features a newly developed pre­amp that not only produces authentic harmonic over­drive but also responds dynamically to your picking
style. Based on semiconductors, this innovative circuitry
simulates the sound-shaping elements of tube amps and
delivers sound quality unparalleled in this price range. It
also provides the dynamics demanding guitarists require
for musical expression.

CLEAN:

Depending on the preamp control settings, the
EDITION BLUE 60-R delivers a variety of contemporary
and Vintage clean tones. At higher VOLUME settings,
the "SoftClick" circuitry delivers that slight edge you
would expect from a Vintage tube amp. If desired, the
CLEAN channel can put out plenty of crunch.

LEAD:

This channel delivers direct, in-your-face classic rock
sounds with a very British feel. The MID control is a very
effective sound-shaping tool; it lets you dial in many
different lead sounds. If you drastically taper off the
mids, the EDITION BLUE 60-R will produce the un­mistakable sound of modern tube amps - ideal for
tapping and heavy-duty power chord riffing.

REVERB:

In the signal chain, the EDITION BLUE 60-R reverb section
is located after the FX loop so you can use it for external
effects and still achieve a clean reverb sound.
Additionally, the reverb level automatically adjusts its
own level when you switch between channels, more for
clean, less for lead.

2.0 JACKS AND CONTROL FEATURES

2.1. FRONT PANEL:

INPUT: Input sensitivity is broad enough to handle guitars
equipped with humbuckers, active pickups, or single
coils.

CLEAN VOL: Determines the CLEAN channel's volume.
Depending on the type of pickups in your instrument,
the amp will begin to clip somewhere around the 12
o'clock setting (SoftClick).

CHANNEL SELECT: This channel selector switch activates
either the CLEAN or LEAD channel. The LEAD channel is
active when the button is pressed.

RED LEAD LED: The red LED illuminates when the LEAD
channel is active.

LEAD GAIN: Controls the amount of distortion in the
LEAD channel.

LEAD MASTER: Determines the LEAD channel volume
level in relation to the CLEAN channel volume level.

EQ SECTION: Common BASS, MID and TREBLE controls for
the both channels. MID and TREBLE controls influence
each other, as is standard in tube amps: if you boost the
treble, the mids are cut and vice versa. This sound­shaping feature allows you to dial in a wide variety of
subtle tonal variations.

REVERB: Controls how much integrated reverb is added
to the signal. Reverb is automatically adjusted for each
channel when you switch channels.

MASTER: Controls the amp‘s master volume level. The
LINE OUT signal is unaffected by the MASTER control.

LINE OUT: Use this jack to feed the signal to the input of
an FX processor. You can also route the signal to a
second power amp or through a RED BOX to a mixing
console.

LINE IN: If you are sending the LINE OUT signal to an FX
processor, connect the output from that processor to
this jack.

FOOTSWITCH: This jack is for a standard footswitch (e.g.
Hughes & Kettner FS-1) and it allows you to switch back
and forth between the CLEAN and LEAD channels.
When using a footswitch, ensure the CHANNEL SELECT
switch on the amp‘s front panel is set to CLEAN.

PHONES: Headphone jack. The speaker is automatically
switched off when a plug is inserted into this jack.

2.2 REAR PANEL:

MAINS: Connect the included Euro-norm mains cord to
this socket. Ensure the amp's voltage rating matches
your local AC voltage rating before you plug the cord
into the wall socket.

CD INPUT: Jack for connecting CD players
(tape decks).

4.0 OPERATING THE EDITION BLUE 60-R

4.1 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.

4.2 THE EDITION BLUE 60-R AND CD PLAYERS

The EDITION BLUE 60-R is equipped with a CD INPUT
located on the rear panel for the connection of a CD
player or another audio source (tape deck, DAT recor­ders). The circuit is controlled directly by the MASTER
circuit of the EDITION BLUE 60-R, which means that you
can use the MASTER knob to adjust the input signal’s
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.
Tip: Most audio playback devices feature a variable
headphones out. Using a corresponding adapter,
you can connect it to the CD INPUT.

Note: Before you switch on the audio playback device,
turn the MASTER knob all the way down. Then turn up the
MASTER knob a tad and dial in the desired balance
levels. Once you’re satisfied with these levels, gradually
turn up the knob to the the desired overall level.

4.3 THE EDITION BLUE 60-R AND SIGNAL
PROCESSORS

The effects loop on the EDITION BLUE 60-R 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 EDITION BLUE 60-

R LINE OUT jack and the processor‘s OUTPUT to the
EDITION BLUE 60-R 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.

4.4 THE EDITION BLUE 60-R AND MIXING

CONSOLES

If you want to feed the EDITION BLUE 60-R's signal to a
mixing console, we recommend you route it through a
Hughes & Kettner RED BOXTM. Patch the signal from the
LINE OUT jack, as this signal path's level is not influenced
by the MASTER setting. The RED BOXTM balances the
signal and simulates a speaker cabinet.

5.0 SERVICE AND PREVENTIVE

MAINTENANCE

The EDITION BLUE 60-R 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. Poor­quality 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.

• 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 EDITION BLUE 60-R.

6.0 TROUBLESHOOTING

1) The EDITION BLUE 60-R 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 EDITION BLUE 60-R 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 LEAD
position. Set it to CLEAN (in this case, CLEAN = off).

• The footswitch is not connected to the EDITION BLUE
60-R. 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 EDITION BLUE 60-R and the
signal's volume level is way too low.

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