Sonos CONNECT interface to mono 70V amplifier
We would like to connect the Sonos CONNECT stereo output to the mono input of common 70V commercial sound amplifiers.. specifically the Bosch PLE-1P240 (https://us.boschsecurity.com/en/products/publicaddressandvoicealar/pacommercialsoundandemerg/plenaeasyline/ple1pxx0usplenaamplifier/ple1pxx0usplenaamplifier_36847). Our question is can the L/R analog output of the CONNECT be combined in parallel/phase using a simple Y-cord arrangement? Or would one need to add a few 1kΩ resistors in series to sum them together (vs 'shorting' together). I wish the CONNECT had an monaural analog output!! And what about sensitivity? Most home audio is -10dBV, whereas pro equipment is typically +4dBU. (The Bosch has input sensitivity of 1Vrms for full output so falls somewhere in between.)
