SYSTEM DESIGN CONSIDERATIONS CONTINUED...

CREATING HIGH POWER AMPLIFIER CHANNELS FOR  
AREAS THAT REQUIRE MORE VOLUME AND POWER

All of the odd numbered amplifier channels of the SC16-50 (channels 1, 3, 5, 
7, 9, 11, 13, and 15) include a power output of 50 or 100 watts that is selected 
using a web based IP Configuration utility. When an odd numbered amplifier 
channel is configured to 100 watts, it’s even numbered adjacent amplifier 
channel (e.g. channel 1 and 2, channels 3 and 4, channels 5 and 6, etc.) is 
deactivated.

There are several situations where having an SC16-50 channel with more power 
is an excellent way to improve the sound. There are also applications where 
having an SC16-50 channel with more power would seem to be appropriate but 
is not recommended.

These are some of the most common DOs and DON’Ts:

1.  Outdoors (DO)

 — Sound dissipates faster outside than it does in a room 

where the walls enclose the sound and reflect it back to the listener. A pair of 
speakers playing into a large patio or yard will greatly benefit from two 100 
watt channels.

2.  Surround Sound Systems (DO)

 — The dynamic demands for the center 

channel are much greater than the left, right or surround channels. This is an 
excellent application for configuring a channel to the 100 watt mode. 

3.  More than one pair of 8 ohm speakers (DON’T) 

— In large rooms or long 

hallways, often the best way to get good background music is to install 
multiple pairs of speakers. You will deliver sound much more reliably using 
two pairs of 8 ohm speakers with four 50 watt amplifier channels than you 
would using two 100 watt amplifier channels connected to two pairs of 
speakers in parallel.
