EFFECTS LOOP – A rear panel effects loop (SEND and RECEIVE jacks) is provided for connecting “serial” outboard

devices such as compressors, and may also be used for parallel type outboard devices (delays, reverbs,

harmonizers, octavers etc.) by using the mix control located on the outboard device. This loop is located right before

the master volume control and is also intended as a Preamp out / Power amp in connection for possible “chaining” of

amplifiers in a Master / Slave configuration. The effects “loop” contains a “normal switch” in the receive jack that

interrupts the signal path when a plug is inserted into the receive jack. The send jack may be used for a aux. output

without breaking the signal path.

AUX INPUT – A 1/4” unbalanced line level aux input is provided that sums directly to the main output bus, controlled

by the master volume control. This input is ideal for practicing with recorded tracks from a CD player, IPOD, or MP-3

player. It is recommmended to use a cable with left & right signals connected to a “Y” jack, summing the signal into the

aux. input jack. Adjust the level of the playback source to balance with the bass guitar’s volume.

HEADPHONE OUT – A 1/4” TRS jack is provided for connection to headphones for silent practice use. A speaker load

is not required. Do not connect this output to anything but headphones.

POWER AMPLIFIER – The SHUTTLE 3.0® uses a state of the art, class D power amplifier design and a high

frequency switch-mode power supply to achieve unprecedented high performance and lightweight packaging.

Switch-mode power supplies convert the AC line directly to high voltage DC, then the precision PWM (pulse width

modulation) inverter creates a new AC power signal at a frequency approximately 2000 times higher than the original

wall frequency of 50/60Hz. This new high voltage, high frequency power signal is then fed into a custom high frequency

transformer that steps the voltage down, a high frequency rectifier and high ESR filter capacitors finish the process

off by converting the high frequency AC signal back to the DC voltages that the amplifier’s internal circuitry uses. One

advantage of this conversion process is that the DC power supply rails are refreshed 1000 times more often than in

traditional linear supplies, thus reducing annoying hum in the audio signal. The high frequency switching is used to

reduce the size and weight of the magnetic and filter components while increasing the performance by recharging the

power supply rails more often. The class D amplifier uses digital PWM techniques similar to those in more familiar

digital to analog converters to reduce the size and weight by a factor of 10 times that of a comparably rated

conventional class AB amplifier. Essentially, a class D amplifier converts the analog signal into a logic level PWM digital

signal with a digital to analog converter, level shifts this PWM signal up to a higher voltage and current and then

reconstructs the analog signal by passing it through what is essentially a power digital to analog converter. Additionally,

we developed our own, proprietary limiting and signal processing techniques to give a distinctly analog feel and sound

to the class D platform. This system provides exceptional performance even for low frequency applications such as

bass guitar.

SPEAKER OUTPUTS – The SHUTTLE 3.0® provides both ¼” and Neutrik Speak-On™ connectors (wired 1+/1-). All

speaker jacks are paralleled. The minimum speaker load is 4 ohms. Do not ground either the “+” or the “-“ outputs.

POWER INPUT – The SHUTTLE 3.0® utilizes an auto-selecting, self-configuring universal power supply that operates

from 100V to 240 volts, 50 to 60 Hz for worldwide use. Simply utilize the proper IEC cord-set appropriate for the country

where the product is being used. There is an AC mains (line) fuse located inside the chassis but is NOT USER SER-

VICEABLE.

CHASSIS DESIGN – The SHUTTLE 3.0’s ULTRA LIGHT design utilizes the highest quality aircraft grade, computer

machined aluminum chassis. To clean the amplifier, nothing more than a damp cloth and a little bit of glass cleaner (like

Windex™) should be used.

GIG-BAG – A custom padded carry bag with shoulder strap is available as an optional accessory from your dealer. This

padded bag is ideal for convenient carrying of the amplifier. Do not operate the amplifier inside the carry bag, as the

chassis aluminum construction is part of the amplifier’s cooling mechanism.
