question

Does the high cut knob act as a crossover? Will the frequencies above the set high cut pass through the HS8S's outputs to go to studio monitors?
Asked by: Dave G.
On the HS8 subwoofer, the high cut control sets the highest frequency output from the sub. The Low Cut control will act as the crossover to the monitor speakers and attenuate the low frequencies before outputting to the connected monitors. This can be bypassed or engaged with the on off switch.

question

Can you turn the sub's volume down and still hear your monitors when connected? Essentially can you bypass the sub when powered on, for just the monitors?
Asked by: Anonymous
Your stereo pair will operate independently of the sub and will not be affected by its volume level. The sub may be bypassed completely as well.

question

Can this be used with HS80M monitors? I've noticed that this subwoofer has a very different frequency response curve to the now discontinued HS10W subwoofer that was designed for the HS80M monitors.
Asked by: Anonymous
Contacted Yamaha and they assure me that it can be used with HS80M monitors. Frequency response is different as the HS8S can go as low as 22hz (HS10W was 30hz). You just need to adjust the cross over frequency until it best complements the HS80M monitors.
