STUDIOFINIX In-Wall 100W Volume Control Knob

STUDIOFINIX 100W In-Wall Volume Control is a passive impedance-matching knob that gives you accurate volume control for paired indoor or outdoor speakers without adding extra power.

Designed to sit flush in a wall plate, the STUDIOFINIX ST-VC100 blends discreet hardware with serious power handling. This passive volume controller supports up to 100 watts and can be wired to multiple speaker pairs, offering a flexible way to balance levels across a whole-house, patio, or multi-room sound system. Because it uses impedance-matching technology, it preserves amplifier stability and speaker load while letting you fine-tune listening zones from a convenient wall-mounted location.

How does this in-wall knob protect my amplifier and speakers?

The ST-VC100 uses impedance matching to maintain a safe load on your amplifier as you change volume settings, reducing the risk of overheating or distortion. Its passive circuit avoids needing external power and keeps signal integrity intact for most home stereo and receiver setups.

• Impedance-matching network prevents excessive load on the amplifier.
• 100W handling capacity for stable performance with compatible receivers.
• Passive design — no power adapters, no additional electronics required.
• Solid mechanical knob for smooth, repeatable level adjustments.

How many speakers can I connect and what setups work best?

This controller supports connections to multiple speaker pairs, making it suitable for whole-house audio or several outdoor zones. It's ideal when you want local volume control for different areas while retaining a single source or amplifier.

• Supports connecting up to eight speaker pairs (wire distribution depends on wiring method).
• Works with indoor and outdoor speakers — patios, decks, garages, and common rooms.
• Best used with a central amplifier or receiver that can drive the total speaker load.
• Mounts in a standard wall box for clean, permanent installation.

What installation and package items are included?

Installation is straightforward for anyone comfortable with low-voltage or speaker wiring and a standard electrical box. The ST-VC100 ships with multiple panels and mounting hardware to fit different décor and wall plate styles.

• Package includes: Volume controller, three face panels, two terminal blocks, six panel screws, two mounting screws, and an instruction manual.
• Fits common wall boxes and accepts standard speaker wire connections.
• No external power or complex programming required — wire, mount, and play.
• Clear labeling on terminals simplifies multi-speaker wiring schemes.

How will this improve everyday listening and outdoor gatherings?

Adding a wall-mounted volume control makes it simple to adapt sound levels for different activities and spaces without getting up to operate the receiver. It helps create consistent background music levels for hospitality, family rooms, or alfresco entertainment while keeping front-end equipment tucked away.

• Quick local volume changes for parties, quiet dinners, or movie nights.
• Discrete in-wall installation preserves room aesthetics.
• Durable knob and faceplates built for frequent use in home and outdoor-adjacent spaces.
• Helps manage multiple speaker zones from a single source.

Who is this for? Install the STUDIOFINIX ST-VC100 if you want a reliable, low-profile way to control volume across rooms or outdoor zones without adding extra amplifiers. It suits homeowners, small businesses, and installers building multi-zone audio systems who need a passive, impedance-matched solution that’s easy to install and blends with interior finishes.
