PANASONIC(RAMSA) / WP-DA112

The RAMSA WP-DA112 is a compact, 1U, two-channel power amplifier with 80 W x 2 (8 Ω continuous output). With a BTL connection, it can be used as a 220 W x 1 (8 Ω load) power amplifier.

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 for rack mounting.)
●Using BTL connection, it can be used as a 220 W x 1 (8 Ω load) power amplifier.
●RAMSA's unique amplification circuit design maintains stable operation even with excessive input or overload.

*1 Based on the Electrical Appliance and Material Safety Act (IEC-J conditions).
*2 This unit uses a Class D amplification system, and due to the characteristics of this system, the signal from the output terminal (speaker output) contains frequency components higher than the audible range. If you connect anything other than a speaker (e.g., a level meter) to the output terminal, it may not function properly depending on the specifications of the connected device.
