1 Passive audio Attenuator. A ground/common‑mode selection jumper is included, letting you choose between grounded or isolated operation based on your setup. A dummy load resistor is also provided: turn it ON if the amplifier is not connected to a speaker to protect the amp, or OFF if a speaker is already connected to avoid unnecessary power loss.
Passive Audio Attenuator High-Level to Low-Level with Common Ground is ideal for professional sound engineers to use during live performances or high-quality audio recording sessions.
