Unbalanced inputs via industry standard RCA connectors accept all standard unbalanced interconnects. Heavy duty insulated five-way speaker binding posts allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs. Remote trigger input and output allow the BasX A4 to control and be controlled by other trigger-enabled equipment. The BasX A4 is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz and will automatically detect and configure itself for the proper line voltage.
Solid Engineering And Quality Construction
A heavy duty linear power supply with an oversized toroidal power transformer delivers plenty of current to drive even difficult speakers. Top quality parts and construction throughout deliver years of reliable trouble-free service. Heavy steel chassis with milled aluminum faceplate offers strength and rugged good looks. Double sided FR4 circuit boards, with plated-through holes, help optimize signal paths and minimize the need for point-to-point wiring.
Strong Yet Silent System Protection
Audiophile-grade fault protection is entirely transparent under normal listening conditions, yet protects the amp and your other equipment from virtually all common faults.
Stylish Look
The redesigned front panel gives the BasX A4 a sleek modern aesthetic that fits well with virtually any room décor.
