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 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 more than 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 an analog to digital 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 proprietary 3DPM™ technology 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. FAN COOLING – The chassis is cooled via a thermal sensing fan design. The fan is always ON but will increase in speed as demand on the amp increases. Do not obstruct the left or right chassis vents. SPEAKER OUTPUTS – The SHUTTLE®6.2 provides two Neutrik Speak-On™ connectors (wired 1+/1-). The speaker jacks are paralleled. The minimum speaker load is 4 ohms. Do not ground either the “+” or the “-” outputs. POWER INPUT – VOLTAGE SELECTOR SWITCH - The SHUTTLE®6.2 utilizes rear panel switch selectable universal power supply that operates from 100V to 240 volts, 50 to 60 Hz for world-wide use. Simply set the switch to the appropriate AC mains voltage (BEFORE connecting to the power source), and utilize the proper IEC cord-set appropriate for the country the product is being used. 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 technician is required to correct the problem. CHASSIS DESIGN – The SHUTTLE®6.2 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 (Glass Plus®) should be used. RACK MOUNTING – The SHUTTLE®6.2 is designed for optional rack mounting in a standard EIA style 19” equipment rack or tour-case. Optional rack mounting kit is available from your dealer. Model# STL-RK. GIG-BAG – A custom padded carry bag with shoulder strap is available as an optional accessory from your dealer. Model# STL-BAG. 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 and cooling fan inlet vents are part of the amplifier’s cooling mechanism. COMBO VERSIONS - REMOVABLE CHASSIS FEATURE—A unique element of the SHUTTLE®6.2 combo models is the ability to easily remove the amp “head” from its protective “saddle” and use the SHUTTLE® amp with larger enclosures for bigger venues. Removal of the chassis is simple. We recommend first unplugging the speaker cable from the back of the chassis. Step One: • Unscrew the large thumbscrews on both sides of the chassis’ saddle. It is recommended to screw these back into the chassis after the amp is removed, so they are not lost. Step Two: • After the thumbscrews are removed, gently slide the chassis forward using both hands to move it forward in the saddle. Step Three: • As the chassis appears from within the saddle, grab it from the front end and remove it completely from the protective saddle. STL6-2-12T COMBO - This model produces 375 watts into the 8 ohm combo configuration and 600 watts when used with an additional 8 ohm extension cabinet. It will be necessary to use a Neutrik Speak-On™ connection when using an extension cabinet with this combo. The speaker is our proprietary high power GBE 12350,...
