Powersoft T904

Powersoft T904 Amplifier 

Features:

• Speaker processing sets a new benchmark for cost-effective amplification for small and medium-sized systems and stage monitors. The T Series can be controlled and configured in various ways.
• Full control with a PC running Armonía.
• Front panel display control for functions such as preset recall (also on each output), gain, delay, mute. This makes it very easy to use for small systems in a rental company. The display also shows available headroom in easy-to-read dB numbers, as well as other condition monitoring parameters.
• Web application. Use any device with a browser (eg a tablet) and access the amplifier via an external WiFi access point for easy control.
• Advanced group controllable equalizer with high cosine filters.
• Large library of presets
• X-series preset compatibility
• Very long FIR filters (42.6 ms)
• Control and monitoring through ArmoníaPlus
