Each model produces 175 watts as a combo and 300 watts with an 8 ohm extension cabinet. The amplifier is configured as a 2 channel – 3 input platform and each channel is equipped with a .” unbalanced line input. Channel 2 offers an XLR balanced microphone input (with phantom power) as well. The 2 inputs on Channel 2 are summed (mixed) together at a 1:1 ratio, so they can be used simultaneously. Each channel then passes through independent 3 band equalizers with a sweepable midrange frequency. Eq

The SHUTTLE MAX 12.0 is equipped with a .” unbalanced INSTRUMENT INPUT; input stage clip detector; MUTE switch with LED indicator; FET and 12AX7 TUBE preamps each with HIGH/LOW gain stage settings and 4 band ACTIVE equalization with 2 sweepable midrange bands; 3 switched SIGNAL SHAPE filters with level adjustments; MASTER VOLUME; proprietary OUTPUT LIMITER; TUNER OUT; AUX INPUT; 3 EFFECTS LOOPS; balanced DIRECT OUTPUT with GROUND LIFT, PRE or POST EQ; and MIC/LINE switches; HEADPHONE OUTPUT; and

the more radical the EQ boost and volume level of the PREAMP VOLUME control, the more possibility of an overload condition. If overloading of the TUBE channel is occurring, adjusting the PREAMP VOLUME and/or PREAMP GAIN controls down will reduce or eliminate the over-load condition and adjusting the MASTER VOLUME control up will return the overall loudness. Note: It is OK for this LED to flash occasionally with your hardest notes played and it may flash even if the FET channel has been selected

This amplifier is built for those that know tone and feel are inseparable. The Black Pearl 30® is meticulously designed with an all-tube signal path, component selection and custom transformers that add up to responsive, thick, rich tone. Inside there are beautifully crafted black military spec PCB’s with robust, precision routed direct-to-point gold-flashed signal traces, neatly dressed wiring and custom tube sockets and retainers; all to ensure that every amp built delivers the Black Pearl 30’

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 more than 1000 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 A

This model has been designed with our unique ULTRA LIGHT unified design process, yielding a 600 watt professional high powered tour-class bass guitar amplifier, weighing only 3.75 lbs! This 2nd generation SHUTTLE® amplifier now incorporates our unique 3-Dimensional Power Management circuitry along with other enhancements like increased tube gain and high efficiency thermal management. Our proprietary 3DPM™ technology insures greater and more solid sounding output while retaining the feel and pla

For countries using 100V, 110V, 115V and 120V AC mains, select the 115V switch position on the Voltage Selector switch. For countries using 220V, 230V, and 240V AC mains, select the 230V switch position on the Voltage Selector switch. There is no externally accessible AC mains (line) fuse. The internal fuse is integral to the SMPS power supply and is not user serviceable. This fuse will not fail except under very unlikely fault conditions to the SMPS, and if this occurs a qualified service techn

The HIGH-MID GAIN control sets the amount of level (cut or boost) for the specific frequency set by the HIGH-MID FREQUENCY control. HIGH FREQUENCY -- The HIGH frequency EQ section is a 4 KHz shelving curve with 15dB of cut or boost. NOTE: These equalizer networks are similar to those found on professional sound consoles and are very useful tools. These active equalizers are very wide response type filters and a little “tweaking” goes a long way. SIGNAL SHAPE – The SHUTTLE®MAX 12.2 is equipped wi

Each channel is equipped with a .” unbalanced line input and channel 1 is also equipped with an XLR balanced microphone input (with phantom power). The 2 inputs on channel 1 are summed (mixed) together at a 1:1 ratio. Each channel offers a 3 band equalizer with a sweepable midrange frequency control. Equalization centers were carefully selected for use with acoustic instruments. Each channel also contains individual send controls to the stereo digital effects circuit. The channel signals are the

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. Spen
