What impedance configuration is recommended for connecting multiple Yamaha speakers?
Do not connect more than two 8‑ohm speakers in parallel; R112, R115, R12M, and R15M are 8 Ω and can be paralleled two per amp channel, while the R215 is 4 Ω and should not be paralleled with another R215 or other models.
