General instructions

Your Blue Sky head´s special features:

On the left side you can adjust the
level of the “DI-Out” with a screw-driver!

"Effect Loop" is a parallel loop with
blending control from 0% till 100% on the
front panel and gain control ±5 dB of
Effect Return. Additional, you can use the
Effect Return either as a mixable Line In or
as a stereo MP3 players input.
It is switched post eq / pre volume-control/
pre-DI out.

The power amp is short circuit, high
temperature and DC voltage protected.
In case of high temperature or DC
current, the red "Protect" LED will come on.

C

the bumpers on the bottom of the amp!

Please ensure adequate ventilation when
rack mounting the amplifier.
Leave a minimum of 5 mm space below
the amplifier. Make sure that the air
entry/discharge vents at the right side of
the housing and the bottom are
unobstructed.

WARNING!
TO REDUCE THE RISC OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE
THIS EQUIPMENT TO RAIN OR MOISTURE.

1.1 Input A Jack

Normal instrument input for active and passive
instruments.

1.2 Input B Jack

Instrument input for high level instruments.
Adjustable via Input B Trim knob.

As a general rule, the trim pot should not be
used to attenuate the input signal so much
that the gain control has to be set higher
than 5 (twelve o'clock).

1.3 Tune Switch (Mute Function)

Mutes all outputs but the Tuner Out on the
back. Can be activated by footswitch.

1.4 A/B Switch

Activates Input A or Input B, enabling
switching of two instruments.

1.5 Overdrive LED

Illuminates when the signal of the preamp
begins to clip (overdrive).

1.6 Gain Control

Matches input signal to preamp. To adjust,
turn knob until the Overdrive LED above the
control only flickers at highest and loudest
peaks. The level in the Effect Loop is then
adjusted to +4 dB and the headroom to
overdrive is 20 dB.

For overdrive function, give more gain. The
Peak LED then lights and flickers more, but
that is ok.

1.7 Trim Input B Control

Pre gain trim for Input B, you can adjust the
level between 0 dB and -20 dB. Attention:

As a rule, keep gain control about halfway
up and adjust trim control accordingly.

2.1 Equalizer with On Switch

Bass, Low Mid, Mid, High Mid and Treble
controls serve to fine tune your sound or solve
acoustical problems on stage. They will be
activated by the On Switch. The Low Mid, Mid
and High Mid frequencies can be changed
by the corresponding H/L switches. They are
centered at 150/230 Hz, 500/800 Hz and 1.2/2
KHz. The increase frequency of the Bass
control is 60 Hz, the decrease is 30 Hz.

3.1 Drive Control

Serves as a gain control when activated, you
can create sounds from soft overdrive to full
tube like overdrive sounds.

3.2 Drive Level Control

Serves as a level control of the Drive section
between 0% and 100%.

3.3 Drive On Switch

Activates the Drive section, can also be
activated by foot switch.

3.4 Voice Control

You can control the intensity of the Voice filter
between low and hot. The filter cuts the low
and high end and additional the mids,
dependent on the control setting. This filter
operates only in the Drive section and is not
active when the Drive section is switched off.

3.5 Voice On Switch

Activates the Voice control when the Drive
section is activated. This feature can also be
activated by foot switch.
