HIGH POWER SPEAKER SELECTOR
Take distributed audio to a new level with the ISS4 low-profile speaker distribution system. The unit includes individual on/off selectors for each listening zone, which distributes one stereo speaker-level signal to four stereo listening zones. The ISS4 Series also provides manual power protection that is activated from the rear panel. The manual power protection switch engages 10 ohm /15 watt resistors wired in parallel, two per channel in the ISS6/ISS4 providing higher power handling capability than the other brands --up to 50% more power! In order to protect your amplifier, the ISS4 handles 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.
