Intruduction
Thank you for purchasing the ALT-70V-50 volume control
from Russound. The ALT-70V-50 is designed to work
with commercial audio systems using either 70V or 100V
amplication. It’s manufactured with a high-quality
autoformer design for long life, excellent frequency response,
low heat build-up, in an easy-to-install package
Considerations
Amplier Type – The ALT-70V-50 can only be used with 70V or
100V ampliers Wattage Rating – The maximum wattage for
speakers being controlled by the ALT-70V-50 is 50 watts. For
example, if controlling 4 speakers tapped at 7.5 watts each,
the total would be 30 watts which is acceptable. If those
same 4 speakers were tapped at 15 watts each, the total
would be 60 watts and this would exceed the power rating of
this volume control.
Installation Location – The ALT-70V-50 is designed for
indoor use but may be installed outdoors if used with a
properly designed weatherproof device cover.
