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. REAR PANEL DIRECT OUTPUT – An XLR balanced direct output is provided for connection to a PA system or directly into a recording studio console or A/D converter. The Direct Out signal may be switched between mic and line level, pre and post EQ, and the audio signal ground may be connected or lifted from pin 1 to eliminate hum due to ground loops. This output is fully protected against 48 volt phantom power and may be used for driving microphone lines of up to 300 feet without problems. TUNER OUTPUT – The SHUTTLE®9.2 is equipped with a fully isolated Tuner Output. This jack is located after the front end scaling preamplifier, but is pre-signal shape and pre-EQ. This output may also be used to drive a separate direct box or high-impedance recording device. The Tuner Output remains active when the amplifier is muted, allowing silent tuning on stage. AUX INPUT – A 1/4” unbalanced line level Auxiliary 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. This input is a tip-ring-sleeve type jack with built-in summing resistors that sum left and right signals when used with a stereo cable. This input will also work with a mono tip-sleeve plug. Adjust the level of the playback source to balance with the bass guitar’s volume. 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 Prea...
