เพาเวอร์แอมป์ ยี่ห้อ EV Electro-Voice รุ่น CPS4.5 Amplifier เครื่องขยายเสียง EV CPS 4.5 เป็นเครื่องขยายเสียงจาก EV ในตระกุล CPS-Series มีกำลังขับ 4 x 500 วัตต์/4 Ohms, 4 x 500 วัตต์/8 Ohms, 4 x 500วัตต์/2 Ohms., High Efficient Class-D Design, Switchable 50 Hz high-pass filter (Hi-Z mode)
เพาเวอร์แอมป์ ยี่ห้อ EV Electro-Voice รุ่น CPS4.5 Amplifier , The Electro-Voice CPS4.5 amplifier offers four independent Class-D Variable Load Drive (VLD) amplifier blocks, each one capable of delivering up to 500 Watts into Low-Z or High-Z loads.
Per default, each channel can be configured individually for max. power output into either 2 Ohms, 4 Ohms, 70V- or 100V- networks without involvement of any output transformers. Being designed for professional audio installation market, special care was taken for long term cost of ownership parameters: In addition to remarkably low current consumption and heat dissipation, the CPS4.5 provides remote standby switching with just 5 Watts consumption in standby mode.
An optional remote control module RCM-810 provides control and supervision features via IRIS-Net, including monitoring of amplifier status and real time load supervision. In addition, via RCM-810 the Variable Load Drive characteristics can be set for max. power output into any load between 2 Ohms and 10 Ohms, in steps of 0.1 Ohm.
The power drawn from the mains network is converted into output power to feed the connected loudspeaker systems and into heat. The difference between power consumption and dispensed power is called power dissipation (Pd).
