Compact stereo amplifier for installed audio

The Rolls PA202 is a 20-watt-per-channel Class-D stereo amplifier built for permanent installation. Its all-metal chassis and bottom mounting points suit ceiling, projector or rack locations where space and heat dissipation are limited. An external 24 VDC IEC power supply is included for immediate setup.

Suits fixed installs needing silent low-power

Integrators running a pair of 4-ohm speakers in a meeting room, classroom or digital-signage display will find the output and connector mix practical. The bridged 40-watt mono mode covers single-zone paging or background music. Buyers who require more output channels, higher continuous power or built-in DSP should look at larger installation amplifiers.

20 watts per channel at 4 ohms stereo

This rating defines the usable loudspeaker load and maximum clean level for typical stereo installations. Bridged operation delivers 40 watts into 8 ohms for mono distribution. The 100 dB signal-to-noise ratio and 0.05% THD confirm the amplifier adds negligible noise or distortion within that power envelope.

Questions about this item

Should I run this amplifier in stereo or bridged mode?

Use stereo mode for two speakers at 4 ohms each, giving 20 watts per channel; switch to bridged mode for a single 8 ohm speaker to get 40 watts.

What does the 20 watts per channel rating mean for my speakers?

Each channel delivers 20 watts into a 4 ohm load, so a pair of 4 ohm speakers will receive that power with 0.05% THD and over 100 dB signal to noise.

How do the screw terminal and RCA inputs connect to my sources?

The PA202 provides both dual RCA and screw terminal inputs, letting you plug line level sources directly or wire bare leads without adapters.
