PANASONIC(RAMSA) / WP-DA112

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

Compact 1U & High-Power Digital Amplifier

●Energy-Saving Design

Significantly reduces power loss through the use of Class D amplification circuitry and switching power supply.


●Space-saving design: Half the thickness. Supports both EIA rack mounting and shelf placement. (Up to 4 units can be stacked and rack-mounted.)

●Can be used as a 220 W x 1 (8 Ω load) power amplifier via BTL connection.

●RAMSA's unique amplification circuit design maintains stable operation even with excessive input or overload.

*1 Based on the Electrical Appliances and Materials Safety Act (IEC-J conditions).

*2 This unit employs a Class D amplification method, and due to the characteristics of this method, the signal at the output terminal (speaker output) contains frequency components higher than the audible range. When connecting something other than a speaker (e.g., a level meter) to the output terminal, it may not function correctly depending on the specifications of the connected equipment.

*3 Based on the JEITA TT-4503B Public Address Amplifier Test Method.
