speaker selector volume control

Many units list a continuous handling rating around 100 watts per channel; some models also specify a peak rating (for example, about 200 watts per channel peak). Specific ratings vary by model, so check the unit’s specifications for exact values.

You can find multi-zone selectors ranging from two-channel A/B units up to four- and six-channel selectors, with many models offering individual volume controls for each zone.

Wiring support varies by model. Some units accept bare speaker wire up to about 14 AWG, while others use heavy-duty screw-type or terminal-block connectors rated for roughly 12–18 AWG. Check the product specs for the exact gauge and connector type supported.

Many models provide independent volume controls for each zone and let you turn zones on or off with front-panel push buttons or dedicated switches, so each speaker pair can have its own volume setting.

Some multi-zone selectors specify minimum amplifier impedance values that change with the number and impedance of connected speakers. For example, minimums of about 4.6–5 Ω are sometimes listed when four 4‑Ω speakers are selected, and higher minimums (around 5.3–6 Ω) are sometimes listed when four 8‑Ω speakers are selected. Check the selector’s specifications for the exact minimums.
