- Use of ORIGINAL Texas Instruments LM3886T IC which has way better specs than mostly used counterfeited copies of this IC.
- IC with metal back plate, transferring heat way better than mostly used plastic versions, resulting in higher power capability.
- Use of EU manufactured, double sided FR4+ board, providing wide, thick (35um) and short tracks, capable of handling 12A+ dynamic currents. This PCB matched IC specs easily.
- Use of brand new, high quality, long life components.
- Mute circuit activated when connected to any voltage level > -2V, f.e. to ground or +5V. While disconnected, amp is active.
- ACin input where the signal is decoupled by a Panasonic 2,2uF/450V MKP capacitor.
- Space for a higher quality (larger) capacitor instead.
- DCin input where the on-board input capacitor is bypassed.
- Larger than normal speaker terminals with 7,5mm spacing.
- Output coil, allowing to connect capacitive loads as well.
- Complete on board power supply with quality secondary fuse holders, 8A rectifier, small caps around it and supply capacitors.
- Two pairs of cost effective, yet quality supply capacitors.
- Next to it a PA-3886 or PA-4766 module could fit sandwiched, together forming a compact 2- or 3-way amplifier pack.
- Just by adding a suitable transformer, the amplifier works.
- This module is completely safeguarded at the output against overvoltage, undervoltage, overloads, shorts to the supplies, thermal runaway and instantaneous temperature peaks.
- All ELTIM modules are RoHs compliant and lead free.
- This module can be sandwich mounted with ELTIM PA-3886, PA-4776 (stereo) and PA-2092 (mono, class D) modules.
