ISP Technologies - ISP-STEALTH PRO

Description

The ISP Technologies STEALTH PRO power amplifier is the first True Professional, high power floor mount guitar power amplifier delivering performance on par with the best guitar amplifiers of the day. The STEALTH is based on analog class A/B amplifier design for excellent sonic and saturated clipping performance not found with Class D power amplifiers, and will exceed the stringent tone characteristics of the professional guitarist. The STEALTH can be used for high SPL gigs and professional stage use. It is powered from an external 19 volt DC switch-mode power adapter like those used with a laptop, but will deliver a TRUE 180 watts RMS continuous output power into an 8 ohm speaker cabinet and greater than 120 volts bridged output voltage swing. The STEALTH can also be used as a stereo 2x 80 watt amplifier @ 4 ohms. It can power a single 4 x 12 cabinet with incredible SPL volume level output or will power two cabinets in a true stereo rig. This incredible small package will deliver more power to a speaker than the typical 100 watt guitar amplifier and will easily interface with any guitar floor system or high performance pedal board. The STEALTH, with 180 watts of power, weighs in at only 1.2 pounds, adding new meaning to light weight guitar systems. The STEALTH also delivers amazing efficiency and it includes internal protection against shorts, open circuits and wrong impedance loads. An internal power on/off output control circuit provides pop free operation for turn on and turn off. The STEALTHs small package size of 9 inches long, 4 inches wide and 2 inches tall allows it to fit with any floor mounted pedal rig.
