Welcome to the EBS-1 VERSION TWO
bass guitar pre amplifier!
Congratulations on your choice of the
EBS-1V2 bass guitar amp!
The EBS-1V2 is a complete bass processing system for studio or st age use. It is
so flexible that filter characteristics, grades
of compression, crossover frequencies,
effects loops in stereo and many other features are all available for individual selection and adjustment. These brief tutorials
will help you get acquainted with some of
the features of the EBS-1V2.
G
ETTING STARTED
…
1. Carefully take your EBS-1V2 out of the
box and remove the plastic wrapping.
Look at it and smile.
2. Check that all the controls are fully
counterclockwise. Locate the FILTER
switch and set it to BYPASS position.
Now the EBS-1V2’s settings are
“zeroed” and ready to be personalized.
3. Plug in your bass.
4. While plucking the string as hard as
you would during your hardest playing,
gradually increase the GAIN knob until
the PEAK LED starts to flash when
you pluck hardest. The VU meter
should now read 0 dB.
5. Move over to the OUTPUT knob and
adjust for desired output volume.
What you are hearing now is the “straight”
sound of your bass. With your EBS-1V2 in
BYPASS mode, the guitar bypasses the
“Tone Zone” and goes to the output unaltered.
Välkommen till basförstärkaren EBS-1
VERSION TWO!
Vi tackar och gratulerar för att du valt
basförstärkaren EBS-1V2.
EBS-1V2 är den kompletta arbetsstationen som passa r för såväl studio som livebruk. EBS-1V2 erbjuder mängder av möjligheter som beskrivs i denna manual, studera den noggrant och praktisera. Men
först av allt följer en introduktion som
hjälper dig att bli bekant med en del av
möjligheterna som finns i EBS-1V2.
A
TT KOMMA IGÅNG
…
1. Packa försiktigt upp din EBS-1V2 ur
kartongen och avlägsna skyddsplasten.
Se och njut!
2. Se till att alla kontroller är max motsols. Leta upp FILTER omkopplaren,
den skall stå i läge BYPASS. Nu är
ljudet “nollställt” och redo att bearbetas.
3. Koppla in din bas.
4. Spela hår t på basen och vrid upp GAIN
ratten tills PEAK dioden börjar att
blinka till - än har du inget hörbart
ljud, men nu har du en perfekt signal
att arbeta vidare med i EBS-1V2. VUmetern till höger skall nu visa cirka 0
dB.
5. Vrid upp OUTPUT-ratten till lämplig
ljudnivå.
Det du hör nu är det “raka” ljudet från din
bas. I BYPASS-läget går hela signalen
förbi hela filtersektionen utan någon påverkan alls.
