Ashly CA 504 - 4-Channel Power Amp

CA-504 Class D Power Amplifier Architect & Engineering Specs

he amplifier shall be a 4-channel configuration of Class D design housed in a 2RU metal chassis with a metal front, including handles on either side. The front panel shall be equipped with input levels knobs and LED indicators for Temp, Current, Input signal (-45dB) and Clip/Mute (one for each channel). There shall also be general LED indicators for Protect Mode and Disable (indicates front panel lock). There shall be a front panel Power button that can switch between Power On and Standby Modes with an LED backlight to indicate status (Solid-ON, Blinking-Standby). The front panel shall be perforated on either side to allow proper air intake for cooling and dual variable-speed fans shall be mounted behind the vent.

The amplifier's rear panel shall be equipped with 3.5mm removeable Balanced Euroblock connectors for each input as well as an XLR/1/4" combo jack. There shall also be a removeable 3-pole 3.5mm Euroblock connector for DC level control per channel. There is also a standby port for remote control of standby functions. A push-buttom switch selects Normal or Bridging operation for each channel pair. A set of DIP switches per channel allow a selectable 80Hz HPF and clip limiter to be switched on or off. There shall also be a DIP switch for selecting amp gain of 26dB, 32dB, 38dB or 1.4V per channel and also DIP switches for front panel lockout and standby port polarity (NO/NC). The speaker outputs shall be a 4-pole 7.62mm removeable Euroblock for each channel pair. The two positive poles are set to deliver bridged power when required. There shall be a locking IEC power connection and the unit shall be supplied with the region-appropriate power cable.

The amplfier shall be capable of driving up to 500W @ 2 or 4 Ohms per channel and 250W @ 8 Ohms per channel. The amplfier can also deliver 1,000W at 8 Ohms or 70V when in Bridge Mode. The amplifier shall have a universal power supply capable of operating from 100-240VAC 50/60Hz and will have a current consumption @ 1/8 rated output of 3A. The amplfier housing shall measure 19" x 3.5" x 14.84" with a net weight of 19lbs.

The amplfier shall be called the Ashly CA-504
