they are active. Press the Speaker 1
Speaker 2 Selectors to activate either
pair of speakers. Both sets of speakers may be
selected simultaneously as long as all speakers
have a nominal impedance of 8 ohms or
greater. However, occasionally the actual
impedance will vary, depending upon the
program material. If the impedance drops to a
point where there may be potential damage
to the equipment, the HK 3470 will go into
protect mode.
Remote Sensor Window: The sensor
behind this window receives infrared signals
from the remote control. Aim the remote at this
area and do not block or cover it unless an
