Sunfire HRS-12, HRS-8, HRS-10 user manual Using the speaker-level inputs

MAIN OUTPUTS

Using the speaker-level inputs

If you are using a receiver which does

not have a subwoofer output or line-level outputs (pre-outs), you can connect

its speaker outputs to the subwoofer’s speaker-level inputs. The front speakers can still be

connected to your

receiver.

The subwoofer’s

internal amplifier
supplies the power
to reproduce the low
frequency range. It
receives a sample of
the signal going to
your front speak-
ers. (An insignifcant
fraction of your
receiver’s
power is
transferred	RECEIVER
to the
subwoofer).
There is no
need to use
the speaker-
level inputs
if you are
using a separate
preamplifier/processor and a
power amplifier. Such systems
are best connected using the
line-level inputs as shown in the		TO
previous diagrams. However, if
you are using the line-level inputs
and there is a excessive amount
of noise or hum present, using the
speaker-level inputs may yield a
lower background noise level.

FRONT SPEAKERS

The subwoofer’s two negative posts are joined internally (com-

mon-grounded). Your receiver/pow- er amplifer must also be internally common-grounded or you cannot use this connection. Contact the

manufacturer of your receiver to make sure its outputs are common grounded.
