Line-Level Input:
Line level is the preferred choice in systems using a separate amp and preamp or in receivers that
have a line level or preamp out. These inputs include a built-in fixed high-pass filter at 80Hz. You should use this
input for ”SUBWOOFER OUT“ connections.
Speaker-Level Input:
Use these inputs if your receiver does not allow access to the preamp.

Warning:
To reduce the risk of electric shock, always switch off the subwoofer and the amplifier and or
receiver when making connections to the subwoofer and speakers.
When to use line connections in conjunction with the internal crossover:
As a general rule, the best results come from using the line-level connections, where sound is passed from
the preamplifier‘s outputs to the subwoofer and on to the amplifier. Many receivers and integrated ampli-
fiers include a ”PREAMP OUT“ and ”AMPLIFIER IN“ on the back panel. If this is the case with your electron-
ics, or if you are using separates, use this input.
Use the "Low Level in". Then set the variable low-pass
filter for an appropriate frequency.
When to use the line connection without the internal crossover:
Most surround sound receivers and preamps now offer a ”SUBWOOFER OUT“ feature.
When using this option, the subwoofer filter will most likely be set within the electronics.
You should then
use
the
Sub300 "SUB IN" connection.
When to use the speaker-level connections:
If your receiver does not offer a ”SUBWOOFER“ or ”PREAMP OUT“ option, or if you wish to run your main
speakers full range, you should use the speaker-level connection.
