Product model: XHM273 Specifications Working voltage: DC 1224 V or AC 512 V Reverberation chip: PT2399 Opamp: NE5532 Key benefits Flexible power options allow integration with a range of audio devices using either DC or AC supplies within the specified ranges. PT2399 based reverberation provides delay and ambience effects suitable for adding space to audio signals. NE5532 opamp delivers reliable, lownoise amplification in the reverb signal path, supporting clear and natural sound reproduction. Designed as a dedicated reverb module for incorporation into DIY projects, amps, mixers, or effect processors. What it does Produces reverberation effects to add depth and space to audio signals. This module focuses on reverb processing using a standard PT2399 implementation and an NE5532 input/output stage for stable performance. Applications and use scenarios DIY audio projects and custom reverb units: Integrate XHM273 into homemade effects pedals, compact amplifiers, or mixer builds to add reverb. Home theater and music systems: Use as a reverb module to enhance room ambiance in small to midsized entertainment setups. Small public address and karaoke setups: Implement reverb to enrich vocals and improve overall sound presence in intimate venue environments. Notes Power supply must comply with the stated DC or AC voltage ranges. The configuration is based on the PT2399 reverberation chip with NE5532 as the primary opamp in the signal path.
