GP-LPSUB
Add a dedicated branch
Create a filtered subwoofer signal from an available line-level output.
A subwoofer path for an analog system
Explore a dedicated subwoofer feed from an available line-level output, or bring subwoofer control together with source selection.
Where it fits
A useful subwoofer path depends on your existing amplifier or preamplifier outputs and the subwoofer’s inputs. Choose the component around those connections.
Available line output
GP-LPSUB
Subwoofer line inputSimplified subwoofer branch, not the main speaker path. Confirm signal level, volume tracking and compatibility in both equipment manuals; a fixed output may not follow your listening volume.

Create a filtered subwoofer signal from an available line-level output.
GP-3000
Switch four line sources while providing a dedicated subwoofer signal, level and phase adjustment.
Before you choose
Confirm whether the available output follows your main volume control.
Check which inputs the subwoofer supports and where its own filtering is applied.
Identify any crossover, level and phase functions already supplied by your system.
A few useful answers
This concept uses a line-level output. Do not connect a speaker output to a line input unless the relevant hardware is explicitly designed for it.
Not necessarily. Choose according to the source-control and subwoofer functions your system already has. The two models can serve different approaches.
Send the amplifier or preamplifier model, subwoofer model, available outputs and how you currently control listening volume.
