PANASONIC / WP-DA204

The WP-DA204 is a digital power amplifier. It employs a highly efficient Class D amplifier circuit and switching power supply, achieving a power-saving design that significantly reduces power loss. RAMSA's proprietary amplifier circuit design maintains stable operation even under excessive input or overload.

Compact 1U, high-power digital amplifier
●Power-saving design
Power loss is significantly reduced by using a Class D amplifier circuit and switching power supply.
●Space-saving design - half the thickness. Compatible with both EIA rack mounting and shelf placement. (Up to four units can be stacked in a rack.)
●Using BTL connection, it can be used as a 220 W x 1 (8 Ω load) power amplifier.
●RAMSA's unique amplifier circuit design maintains stable operation even under excessive input or overload.
