For sending powerful audio signals to up to 8 separate listening zones, the OSD ISS8 speaker selector really delivers. This is a powerful audio distribution system that is designed so that you can expand it at a later time. It handles 140 watts per channel of total input power without using the manual protection and 70 watts per channel with the protection engaged.
A multiple speaker bus connection unit is a clean and efficient way of controlling a house-wide or facility-wide sound system from a single amplifier. With the OSD ISS8 speaker selector, you can distribute 1 stereo speaker-level signal to 4, 6 or 8 stereo listening zones, and it has individual on/off selectors for each zone. Manual power protection, activated from the rear panel, engages 10 ohm/15 watt resistors that are wired in parallel, with 3 per channel in the ISS8 model. This provides up to 50 percent more power than with other brands and protects your amplifier.
The ISS4, ISS6 and ISS8 are low-profile speaker distribution systems with individual on/off selectors for each listening zone which distribute one stereo speaker-level signal to eight, six or four stereo listening zones. The ISS Series also provides manual power protection that is activated from the rear panel.
