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 for use. This is normal and is due to the Mixing topology for the 2 channels. PREAMP VOLUME CONTROL – This control sets the volume of the preamp after the INPUT and TUBE gain stages and before the EQ controls. Use this control in conjunction with the PREAMP GAIN control and the MASTER VOLUME control for your overall output level. ACTIVE EQUALIZATION (both channels) – The SHUTTLE MAX 6.0 contains two active 4 band equalizers (one for the FET and one for the TUBE channel) each with 2 sweepable parametric midrange frequency networks (low-mid and high-mid) that offer 15dB of cut or boost with a bandwidth of approximately 1 octave wide. These are slightly over-lapping filters to provide ultimate flexibility. Parametric filters are typically (but not always) used to reduce or remove offending frequencies in the instrument’s pickup response, or boosting response to achieve a particular voicing. Spend some time experimenting so that the process becomes creative as well as corrective. LOW FREQUENCY CONTROL – The LOW FREQUENCY EQ section is an 80 Hz shelving curve with 15dB of cut or boost. LOW-MID FREQUENCY FILTER -- The center frequency of the LOW-MID filter is continuously user adjustable from 120 Hz to 2 KHz with a single control. The LOW-MID GAIN control sets the amount of level (cut or boost) for the specific frequency set by the LOW-MID FREQUENCY control. HIGH-MID FREQUENCY FILTER -- The HIGH-MID frequency is continuously user adjustable from 300 Hz to 5 KHz with a single control. 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 6.0 is equipped with 3 SIGNAL SHAPE circuits, each with a level control to 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 adjusts 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 footswitch. 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 o’clock positions. OUTPUT LIMITER – The SHUTTLE MAX 6.0 contains an internal power amplifier “Soft Clip” LIMITER. This LIMITER allows simulation of the output stage saturation of a tube power amp output stage as the amplifier nears it maximum power. The LIMITER is a compound multi-stage analog circuit, is quite graceful in nature and is particularly musical sounding, even when driven hard. The amber output “LIMIT” LED shows limiting action for the first 6dB above the illumination threshold and then indicates power amplifier clipping as the power amplifier gradually transitions into gentle clipping. NOTE: In order to achieve full power from the amplifier the LIMIT LED may be flashing regularly. If the LED is illuminated constantly then the amplifier output could be clipping. With our unique LIMITER circuit you may not hear drastic “harsh” distortion but it is recommended to keep the LIMIT LED away from the “constantly on” state. 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...
