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

MOUNTING HOLES (2)

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

HEADPHONE JACKS
(TOTAL 10)

rated for eight ohms, the headphone should
be at least eight ohms.

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.

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 =

impedance per headphone

number of headphones being connected

Example: Find the combined impedance of ten
300-ohm headphones

combined headphone impedance =

300 ohms per headphone

10 headphones

= 30 ohms

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.
