16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS
SYSTEM DESIGN CONSIDERATIONS CONTINUED...
SPEAKER COMPATIBILITY
Any SI-1650 amplier channel congured 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
amplier placement, see Installation Considerations on page 29).
Any odd numbered SI-1650 amplier channel congured 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 amplier channels congured
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 amplier 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).
