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 Switch Box (Ass 0301)

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.Model: AS0301Features:● High-quality silver alloy contact switches● 2.5 mm² monocrystalline silver-plated copper wiring● Pure copper gold-plated banana terminals● Hand-soldered with precision using a professional soldering stationNet Weight: 2.94 lb / 1350 gPackage Weight: 3.44 lb / 1580 gUnit Dimensions: 8.66×9.21×2.36 in (22×23×6 cm)Package Dimensions: 11.2×10.3×3.6 in (28.5×26.2×9.2 cm)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, orTurn off the amplifier → Switch channels → Power it back on.

• 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.
