ACTIVE EQUALIZATION – The SHUTTLE

9.2 contains an active 3 band equalizer with sweepable parametric mid range

frequency control. This equalizer, similar to those found on professional sound consoles, is a very useful tool. The low

frequency EQ section is an 80 Hz shelving curve with 15dB of cut or boost. The high frequency EQ section is a 4 KHz

shelving curve with 15dB of cut or boost. The parametric sweepable-mid frequency section features 15dB of cut or boost

with a bandwidth approximately 1 octave wide. The center frequency of this filter is continuously user adjustable from 150

Hz to 2 KHz with a single control. This filter is typically (but not always) used to reduce or remove offending frequencies

in the instrument’s pick-up response, or boost response to achieve a particular voicing. Spend some time experimenting

so that the process becomes creative as well as corrective. Note that our active equalizers are very wide response and a

little bit can go a long way.

SIGNAL SHAPE – The SHUTTLE

9.2 is equipped with 3 Signal Shape circuits. The L.F. BOOST adds low frequency

peaking gain in the 38-67 Hz band. This filter is especially effective when used with a 5 string bass. The MID SCOOP

switch generates midrange cut centered at approx. 600 Hz, the H.F. ATTACK adds a peaking high frequency boost in the

2.25-8 KHz band. LED indicators are provided to visually show when each filter is engaged. Each filter Q (bandwidth)

is optimized for its particular functions and is different for each filter. These functions are also foot-switchable from the

optional 4 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 that the amp is in “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 red “THERMAL” LED indicates that the amplifier has over-heated, engaged the protection circuit and shut down.

This circuit is self-resetting when the offending condition is corrected, i.e., blocked fan vents, stuck fan, 2 ohm operation,

etc.

• The blue “SIGNAL” LED indicates that the power amplifier is receiving signal (over several watts output) and is

performing properly.

• The “PEAK” LED indicates that the power amp is near its maximum power. Under high output conditions it is normal for

this LED to light with the strongest pulses of the signal. Driving hard beyond this point will cause the amplifier to

gradually begin to clip which may become audible.

3DPM™ --- 3 DIMENSIONAL POWER MANAGEMENT --- Our proprietary 3DPM™ technology insures greater and

more solid sounding output while retaining the feel and playability of a more traditional tube based power amplifier. When

driving the power amp hard the player can feel increased heft and girth of the individual notes, while maintaining dynamics

and articulation. The result is an amplifier that achieves a more 3 dimensional tone and feel, like a tube amplifier power

section, without the anemic flatness other amplifier designs can exhibit.
