AMBER 40 is a two-channel guitar head of classic tube amp architecture built using
analogue (except for reverb) semiconductor components. The analysis of classic tube amp work
made it possible to create an amplifier which features non-linearity, compression and typical for
tubes distorted sound.. A distinctive feature of AMBER is the power amp overdrive and the output
power control system. Thereby the volume change for overdriven tones is made by changing the
output power of the amplifier which guarantees fixed timbre within full volume range. The
architecture of transformer power amplifier also allowed to achieve constant output power for 4, 8
and 16 ohm speakers.
AMBER 40 features a CLEAN/CRUNCH type channel and OVERDRIVE type channel. Each of
these channels has its own passive EQ section and is able to work in one of six modes with
different compression and gain. The possibility of saving channel modes extends the range of
available sounds while playing. Power LEVEL function (which can also be saved) makes it possible
for the user to control the volume while playing.
The whole amplifier is complemented with the high-quality digital reverb, enabled FX loop, four
push-buttons footswitch and MIDI input and output. The selected footswitch mode allows to adjust
the functionality of the amplifier to the preferences of the player. There are six modes: from the
simplest, as in typical two-channel amps, to the modes using banks and presets. The MIDI input
allows to control the amplifier by the MIDI controller, while the MIDI output allows to control the
MIDI effect by the amp.

Speaker connection
Connect speakers before use. Do not switch the amplifier on without a loudspeaker
connected. Check the impedance and power rating of your speakers. Connect a
speaker or speakers with a total power of 70W or more.
Connected speakers must provide impedance matching. The table below shows how to connect
the speakers according to their impedance. Impedance mismatch can activate overload protection
(see Troubleshooting section).

AMBER 40 features a serial FX LOOP with signal level switch (see Back panel).
The -10dBu level should be used for stompbox-type effects, while the +4dBV level is for the rack-
type effects. RED colour of FX LOOP indicator means the FX Loop is active. Enabling/disabling of
the loop in the BLUE and CYAN modes (see Footswitch working modes) is done by footswitch
button or front panel FX LOOP switch (upwards). In the preset footswitch modes the status is
changed by front panel FX LOOP switch (upwards) and is stored as a preset parameter. This
allows to change the amp's sound and simultaneously switching on/off the effect plugged into the
FX LOOP.

Der AMBER 40 ist ein Zweikanal-Gitarrenverstärker, analog gebaut nach klassischer
Röhrenverstärker Architektur unter Verwendung von Halbleiterkomponenten (Ausnahme Digitaler
Reverb). Die langjährige und intensive Analyse Klassischer Röhrenverstärker (Sound und
Technologie) machte es uns möglich, einen Verstärker zu entwickeln der über Nichtlinearität,
Kompression und einem für Röhrenverstärker typischen verzerrten Ton verfügt. Eine Besonderheit
des AMBER 40 ist die Endstufenverzerrung und das Steuersystem der Ausgangsleistung. Die
Lautstärkeänderung der übersteuerten Töne wird durch Änderung der Ausgangsleistung des
Verstärkers hergestellt. Die besondere Konstruktion der Transformatorendstufe erlaubt eine
konstante Ausgangsleistung für 4, 8 und 16 Ohm-Lautsprecher.
Der AMBER 40 verfügt über einen "CLEAN/CRUNCH" Kanal und einen "OVERDRIVE" Kanal.
Jeder dieser Kanäle verfügt über eine eigene passive EQ-Sektion und ist in der Lage, in einem von
sechs wählbaren Modi mit unterschiedlicher Kompression und Verstärkung zu arbeiten. Die
Möglichkeit, Kanal-Modi zu speichern erweitert die Vielfalt der verfügbaren Sounds während des
spielens. Die Power LEVEL Funktion (die auch gespeichert werden kann) macht es möglich, dass
der Benutzer die Lautstärke während der Wiedergabe steuern kann.
Der Verstärker ist mit einem hochwertigen digitalen Reverb, FX Loop, MIDI Eingang, MIDI
Ausgang und einem 4 Fach Fußschalter ausgestattet. Der auswählbare Fußschalter-Modus
ermöglicht es dem Spieler den Verstärker in verschiedenen Arbeitsweisen zu betreiben und diese
auf den Spieler individuell einzustellen und anzupassen. Es stehen sechs Modi zu Verfügung von
den einfachsten, wie z.B. in typischen Zweikanal-Verstärkern, bis hin zu Modi mit Bänken und
Presets. Der MIDI-Eingang ermöglicht es den Verstärker über einen MIDI-Controller zu steuern,
während der MIDI-Ausgang es ermöglicht den MIDI-Effekt direkt über den Verstärker zu steuern.

Lautsprecheranschluss
Den Verstärker nicht ohne einen angeschlossenen Lautsprecher einschalten.
Überprüfen Sie die Impedanz und Leistung der Lautsprecher. Schließen Sie einen
oder mehrere Lautsprecher mit einer Gesamtleistung von min. 70W an.
Die Impedanz der angeschlossenen Lautsprecher muss eingehalten werden.
Die folgende Tabelle zeigt, wie Sie die Lautsprecher Impedanz entsprechend anschließen.
Nichteinhaltung der Impedanzen kann zum auslösen des Überlastschutz führen (siehe Sektion
FEHLERBEHEBUNG).
