Connecting the HD-10 to a Louroe Audio Base
Station
Connect the HD-10 into the headphone jack located
on front panel of the Louroe Base Station, using
1/8”(3.5mm) plug from HD-10.
Determining Audio Source Capacity
All audio sources have an output load
capacity, called output impedance. This
output impedance is specified using the term
“ohms”, which is often represented by the
symbol “?”. Headphones are also rated in
ohms, and when connecting a headphone to
an amplifier, it is important that the ohms
rating of the headphone should be equal to
or greater than the ohms rating of the
amplifier. For example, if the amplifier is
rated for eight ohms, the headphone should
be at least eight ohms.
Headphone impedance is dramatically
reduced when connecting multiple
headphones. Therefore, it is necessary to
use the following formula to determine the
combination impedance of several
headphones.
combined headphone impedance =
combined headphone impedance =
impedance per headphone
300 ohms per headphone
number of headphones being connected
10 headphones = 30 ohms
Example: Find the combined impedance of ten
300-ohm headphones
The audio source must have an impedance of
30ohms or less.
Note: This formula works when all
headphones are of the same
impedance. It is recommended that all
headphones be of the same type and
impedance to insure uniform output
volume for all listeners.
