GSM GSM GSM GSM GSM GSM GSM GSM GSM GSM GSM GSM Datasheet Sound Processors for Home Theater Systems 7.1ch Sound Processor with Built-in Micro-step Volume BD34701KS2 General description Key Specifications The BD34701KS2 is an 8ch independent volume system. Total harmonic distortion: 0.0004%(Typ.) The system is designed in such a way, that it can be Maximum output voltage: 4.2Vrms(Typ.) used as a 7.1ch surround system. Micro-step volume Output noise voltage: 1.5uVrms(Typ.) can reduce the switching shock noise when volume Residual output noise voltage: 1.0uVrms(Typ.) changes, so it can achieve a high-quality set. Cross-talk between channels: -105dB(Typ.) 8ch dual input selector for zone 2 and multi channel Cross-talk between selectors: -105dB(Typ.) input enable the connection of a number of sources. Package W(Typ.) x D(Typ.) x H(Max.) SQFP-T52 12.00mm x 12.00mm x 1.50mm Features 8ch input selectors Micro-step volume can reduce the switching shock noise when volume changes. Zone 2 can support. 2-wire serial bus control, corresponding to 3.3/5V.
