Connecting to Other Devices
Connecting to Audio Equipment
If you connect the HP307 to powered speakers or to an audio system that has line input jacks, you’ll be able to hear the HP307’s sound from your powered speakers or audio system. If you connect your digital audio player or other audio playback device to the HP307, you’ll be able to hear its sound via the HP307. Use audio cables (sold separately) to make connections.
Caution when making audio connections
To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.
When connection cables with resistors are used, the volume level of equipment connected to the inputs jacks may be low. If this happens, use connection cables that do not contain resistors.
