Thank you for viewing. This is a professional power amplifier developed by Victor. It's a 4-channel amplifier with a powerful 100W x 4 output (BTL 200W x 2), making it a versatile amplifier suitable for a wide range of applications, including broadcasting equipment, PA systems, and large speaker operation. It features a fanless, silent design and a robust build, ensuring stable performance even after years of use. The unit being offered for sale has numerous scratches and cosmetic damage on the cover (chassis), but there are no functional issues. It's recommended for those seeking high power, for PA use, for pairing with vintage speakers, and as a practical unit for listening purposes. *Due to the packaging size, the rack mounting brackets on the back will be removed for shipping. Please understand.* #Victor #PSA1004 #PowerAmplifier #PAEquipment #ProfessionalAmplifier #4chAmplifier #HighPower #AudioEquipment #VOSS #UsedAudio #Vintage #DTM #Recording
