Stoltzen SSA220 ClassD Amplifier

SSA220 is a small digital amplifier (Class D), with EQ control and MIC mixer function. It is in small cage but with powerful functions, including bridge connection, dual-mono, EQ control, microphone mixer etc.
It has a good application in different places, including classroom, small meeting room, lecture hall, bar, pub etc.

Features:

·         2x20Watt@4Ohm as the default amplifier output.

·         Bridge connection function. The user can switch the PA2B to be 1x40Watt@8Ohm by bridge connection.

·         Dual-mono function. The user can sum up the stereo audio to two times mono audio.

·         Microphone mixer function. The microphone will be mixed to the line audio output, and separately controllable.

·         MIC input supports 48V phantom power, condenser microphone available.

·         MIC port with balance switching, can support balance/unbalance signal, suppress the external noise effectively.

·         Ducking power technology. It keeps detecting the audio and MIC input, and reducing the power consumption when there is no input coming.

·         Ultra low inrush current, no need for power sequencing. This allows multiple PA2B to be powered on simultaneously without overloading power circuits.

·         Convection cooled, fan is not needed.

·         Two stereo audio inputs, switchable by button, remote or RS232.

·         Fast switching speed. It is the high speed for the good performance.

·         Volume/Bass/Treble controllable by buttons or RS232

·         Line audio output, with volume control

·         Optional control by IR remote.

·         Extensibility: It can be controlled by PTN panel (WP8 & WP19), optional function.

·         Antistatic case design: providing good protection for long-term and stable performance

·         LED indicator, for power and working status.
