SIGNAL SHAPE – The SHUTTLE
adjust the amount of level the tone shaping circuit produces.
L.F. BOOST – This filter adds low frequency peaking gain in the 35-65 HZ band range. This is especially effective
when used with a 5 string bass. The level control has a range of 0 to +7dB. This filter is unique in that it provides
compound, asymmetrical slopes critical to achieving well-controlled low frequency extension.
MID SCOOP -- Engaging this switch generates a midrange frequency cut centered at 600 Hz. The level control ad-
justs the amount of cut from 0db to –15dB.
H.F. ATTACK -- adds a peaking high frequency boost in the 2.5K – 16 KHz range. The level control has a range of 0
to +7dB.
LED indicators are provided to visually show when each filter is engaged. Each filter Q (bandwidth) is optimized for
its particular function and is different for each filter. These functions are also foot-switchable from the 5-button foot-
switch.
The switches on the amplifier's faceplate must be in the out position for the footswitch to work properly.
MASTER VOLUME – The MASTER VOLUME control adjusts the overall volume of the amplifier and the effects
return. Typically, best results are obtained when this control is operated between the 9:00 and 3:00 positions.
MASTER SECTION STATUS INDICATORS -
•The "POWER" light indicates that the amplifier is ON and the low voltage power supplies are active.
•The red "PROTECT" LED indicates when the amp enters "PROTECT" mode. This LED may flash during power turn-
on and turn-off. This is normal. It will also illuminate during any internal fault condition. If this happens, turn the amp
off and consult a repair technician.
•The blue "SIGNAL" LED indicates that the power amplifier has received signal (over several watts output) and is
performing properly.
•The Amber "PEAK" LED indicates that the power amp has reached maximum power. Under high output conditions it
is normal that this LED will light with the strongest pulses of the signal. Driving hard beyond this point will cause the
amplifier to gradually begin audible distortion.
GENERAL GUIDELINES FOR SETTING YOUR INPUT SIGNAL – There are a wide variety of variables that can
impact your signal and tone in the design of all amplifiers. Below are some basic guidelines to consider when begin-
ning to set your tone on the SHUTTLE
•Begin a basic set up for the FET and TUBE channels with all EQ settings set at the 12 o'clock position.
•If you are using an Active bass, begin with the channel GAIN switches in the LOW positions. For a Passive bass
begin with these set in the HIGH position.
•Set the GAIN control for each channel to approx. 10-12 o'clock positions. Now, bring up the PREAMP VOLUME
control to approx. the same position ---10-12 o'clock.
•At this time, you may want to set the MASTER VOLUME to the 9 o'clock position.
•From this point you can set your EQ settings to your desired taste.
•If the O/L light on either channel is blinking, you should back down either your PREAMP GAIN control or PREAMP
VOLUME control so that it blinks with only the very hardest notes played --- or not at all.
•If you set radical EQ settings this may impact the level of your signal causing the O/L light to engage more. If so,
then reduce your PREAMP VOLUME control a little more.
•In the TUBE channel the O/L light will not sense TUBE OVERDRIVE so you will be able to get varying amounts of
TUBE compression or distortion without the O/L light coming on.
channel, then you will want to reduce your PREAMP VOLUME control.
•As you fine-tune your settings and levels and get your tone ready for a performance level of output, it is suggested
you try to keep your PREAMP VOLUME levels and your MASTER VOLUME levels operating in approximately the
same range, generally between 9 – 3 o'clock. This is not a hard-fast rule but it is a good starting place.
