Owner's of the Niles Audio Stereo Amplifier SI-1230 gave it a score of 0 out of 5. Here's how the scores stacked up:
25
OPERATION
OPERATION
Power LED
The power LED indicates that the AC cord is plugged into a working AC power
receptacle and that the power switch is in the "On" position.
Active LED
The rear panel turn-on mode switch determines when and how the amplifier will
turn on. The "Active" LED indicates that the amplifier is on.
Power Switch
The front panel switch is a master or "vacation" power switch. No matter which
turn-on mode you have selected, the master power switch will turn off all cir-
cuitry—including the sensing circuitry. If you are going on vacation and/or
would like to reduce power consumption while you are away, turn the master
power switch “Off” (push the rocker switch out). When you would like to return
to normal operation, turn the switch "On" (push the rocker switch in).
D.C. Protection
In the event a damaging D.C. signal becomes present on any of the speaker ter-
minals, the D.C. protection circuit shuts down the entire amplifier and the red
LED labeled “Protection” illuminates. To reset the amplifier you must turn the
front panel power switch “Off” and then “On.”
Listening at Higher Volumes
Thirty watts is enough power to play a conventional speaker in a normal sized
room loudly enough to completely drown out conversation. Even at levels like
that, the SI-1230 will sound clear and clean. However, it requires more power to
achieve a reasonable volume of sound in a large room than it does in a small
room. It is possible (even if you are not a teenager) to turn the volume so high
that the amplifier runs out of power. This creates "clipping" distortion.
