3(1)-in-1(3)-Out Speaker Amplifier Switcher Stereo Home Audio Selector Switch Box Banana Plug Silver Plated Audio Cable 3 to 1 (1 to 3) Banana Jack($113.99Value)

Description

Seamlessly switch between 3 amplifiers to 1 speaker pair OR 1 amplifier to 3 speaker pairs. Perfect for A/B/C testing, home studios, or multi-zone setups without cable swapping. COMPATIBILITY ASSURED: Compatible with all standard banana plug speaker cables to seamlessly integrate into any home audio system with speakers. Passive design requires no external power. Simply toggle the PRI/SEC switches to select channels (A/B/C). Protects amplifier/speaker ports from wear caused by frequent plugging. DURABLE CONSTRUCTION: Solid metal casing construction ensures lasting dependability and reliable performance year after year. Note: No built-in load protection for tube amps. Always power off before switching channels or pair with a tube-safe switcher. Ideal for solid-state amplifiers.

Used for switching between amplifiers and speakers in a home audio system: selecting one of three amplifiers (AMP) to output to one pair of speakers; or using one audio amplifier to select one of three pairs of speakers to play music. It is not a mixer and cannot output simultaneously (channels A/B/C cannot work at the same time; only one channel can be active). No power supply is required—manually select Channel A, B, or C.

● 3 Amplifiers → 1 Pair of Speakers:
Use the two switches on the front panel to select output from Amplifier A, B, or C to drive one pair of speakers.

● 1 Amplifier → 3 Pairs of Speakers:
Use the two switches on the front panel to select one of three speaker pairs for output from a single amplifier.

How to Use:

PRI-Select: Primary selection switch (left)

SEC-Select: Secondary selection switch (right)

● Select Channel A: Set the left PRI-Select to A; ignore the right switch.
● Select Channel B: Set the left PRI-Select to B/C, and the right SEC-Select to B.
● Select Channel C: Set the left PRI-Select to B/C, and the right SEC-Select to C.

Purpose: Eliminates frequent cable plugging/unplugging to protect socket contacts, ideal for audio equipment comparison. A practical solution to avoid wear from speaker wire changes.

Note:
This switcher has no internal protection or impedance matching circuits. However, for most tube amplifiers, it is highly unsafe to power on without a load (no speakers connected). If you own a tube amplifier, either:

Use a switcher with tube protection, or

Turn off the amplifier → Switch channels → Power it back on.
