SPEAKER COMPATIBILITY

Any SI-1650 amplifier channel configured to the 50 watt mode is capable of driving a 4 ohm impedance speaker load. No more than two 8 ohm speakers or no more than one 4-6 ohm speaker can be safely connected to a single channel. Proper ventilation of the SI-1650 is critical when driving lower impedance loads. If the SI-1650 is not properly ventilated, the protection circuits may activate and shut off the channel at higher volume levels (for more information on proper amplifier placement, see Installation Considerations on page 29).

Any odd numbered SI-1650 amplifier channel configured to the 100 watt mode is capable of driving an impedance load of 8 ohms. Proper ventilation of the SI-1650 is critical when driving an 8 ohm load with amplifier channels configured to 100 watts. If the SI-1650 is not properly ventilated, the protection circuits may activate and shut off the channel at higher volume levels (for more information on proper amplifier placement, see Installation Considerations on page 29).

When designing your system, try to specify 6-8 ohm speakers (Niles offers a complete line of in-wall, in-ceiling, outdoor and home theater loudspeakers with all models rated from 6-8 ohms).
