4-channel mini installation amplifier 4 × 50 W @ 4 Ohm

Professional mini amplifier
4 × 50 W Class D amplifier 4 ohms
Small format 1/3 19" rack, 1 RU
Silent operation with passive cooling
Connection options for remote control of standby mode
External 100–240 V power supply
Operates in 4-channel mode or as a bridge for 2 channels at 100 W in high power mode
Mounting plates for flexible, unobtrusive installation, even above suspended ceilings
Automatic standby mode to save energy
Four loudspeaker outputs with terminal blocks
User-friendly control panel with signal, clip and protection LEDs
Optional rack tray for combining with other products in the TICA® series

Part of TICA® series combines compact size, passive cooling and high efficiency – ideal for a wide variety of audio fixed installations.

The highly efficient 50 W 4-channel Class D amplifier can drive low-impedance speakers in different zones.

Thanks to its compact dimensions of 142 x 44 x 222 mm and the supplied mounting plates, it can be discreetly installed almost anywhere: behind screens, under tables or even in ventilation ducts and above plenum ceilings. Alternatively, it also fits in 1/3 19-inch racks. Use the optional rack tray to place up to three TICA® series products side by side to create a system that exactly meets your requirements and takes up minimal rack space.

Terminal block connectors on the balanced line input and speaker output make wiring easier.

With the remote control, you can put the power amplifier into standby mode at any time, even when it is hidden. The optional auto standby function saves energy when there is no audio transmission.

The perfect solution for professional installers and users looking for a compact, highly efficient and easy-to-integrate solution.
