be seated midway between the two loudspeak- ers, and the same distance from the speakers as the speakers are from each other. The speakers must be placed facing parallel and evenly with each other so that their baffles are in the same plane. Press the button again to return to Stereo mode.
&FM/AM Selector: Press this button to select the tuner as the input to the receiver. When the tuner is in use, press this button to change between the AM and FM frequency bands.
*FM Mode Selector: Press this button to select the Stereo or Mono mode for FM tuning. In the STEREO mode, a Stereo indicator will light in the Main Information Display Û, and stereo reception will be provided when sta- tions are transmitting stereo signals. In the MONO mode, the left and right signals from stereo broadcasts will be mixed together and reproduced through all channels. Select MONO for better reception of weak signals. VMAx will have no effect in MONO mode.
(Sleep Button: Press this button to place the unit in the Sleep mode. Each press of the button selects the amount of time that will remain before the unit automatically goes into the Standby mode, as shown in the Main Information Display Û, in the following order:
| | | 90 | | 80 | | | 70 | | 60 | | 50 | |
| | | min | | | min | | min | | | min | | | min | |
| | | | | | | | | | | | | | | | |

ÓBass Control: Turn this control to modify the low-frequency output of the left and right channels by as much as ±10dB. Set this control to a suitable position for your taste and room acoustics.
ÔTreble Control: Turn this control to modify the high-frequency output of the left and right channels by as much as ±10dB. Set this control to a suitable position for your taste and room acoustics.
Balance Control: Turn this control to change the relative volume for the left and right channels.
ÒVolume Control: Turn the knob clockwise to increase volume, counterclockwise to decrease the volume.
ÚVolume/Mute Indicator: This indicator will glow green when the HK 3470 is turned on. Its position will enable you to judge the relative volume of the unit even when the speakers are muted or turned off. When the indicator is pointing toward the left, as in an “8 o’clock” position, the volume is low; when it is pointing to the right, as in a “3 o’clock” position, the volume is loud. When the unit has been muted by pressing the Mute button 5, the indicator will flash.
ÛMain Information Display: This display delivers messages and status indications to help you operate the receiver.
ÙSpeaker Selection Indicators: These indicators light as a green LED next to the des- ignation for each speaker pair to show when they are active. Press the Speaker 1 6 or Speaker 2 7 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.
ıRemote 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 external remote sensor is installed.
