Resumen del manual


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 with 3 SIGNAL SHAPE circuits, each with a level control to adjust the amount of level the tone shaping circuit produces. 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 footswitchable from the 5-button footswitch. The switches on the amplifier’s faceplate must be in the out position for the footswitch to work properly. 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 – This filter adds high frequency peaking gain in the 2.5K – 16 KHz range. The level control has a range of 0 to +7dB. 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 blue SIGNAL LED indicates that the power amplifier has received signal (over several watts output) and is performing properly. • The amber PEAK LED indicates that the power amp has reached maximum power. Under high output conditions it is normal that this LED will light with the strongest pulses of the signal. Driving hard beyond this point will cause the amplifier to gradually begin audible distortion. NOTE: The PROTECT circuit senses both AMP A and AMP B power amp modules. It is possible that if one module goes into the PROTECT mode, the remaining power amp module will perform properly. In an emergency situation, if the PROTECT circuit engages during use, it is possible to unplug the failed power amp speaker cable at the amplifier connection and continue on with the remaining power amp module to complete the performance. Additionally, this amplifier utilizes redundant backup preamp power supplies, so that in the unlikely event of a power amp module failure, the backup power supply will automatically take over and supply the preamp insuring that the remaining module and direct output signal continues to function normally. 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. GENERAL GUIDELINES FOR SETTING YOUR INPUT SIGNAL – There are a wide variety of variables that can impact your signal and tone in the design of all amplifiers. Below are some basic guidelines to consider when beginning to set your tone on the SHUTTLE®MAX 12.2. • Begin a basic set up for the FET and TUBE channels with all EQ settings set at the 12 o’clock position. • If you are using an Active bass, begin with the channel GAIN switches in the LOW positions. For a Passive bass begin with these set in the HIGH position. • Set the GAIN control for each channel to approx. 10-12 o’clock positions. Now, bring up the preamp VOLUME control to approx. the same position ---10-12 o’clock. • At this time you may want to set the MASTER VOLUME to the 9 o’clock position. • From this point you can set your EQ settings to your desired taste. • If the O/L light on either channel is blinking, you should back down either your preamp GAIN control or preamp VOLUME control so that it blinks with only the very hardest notes played --- or not at all. • If you set radical EQ settings this may impact the level of your signal causin...
