Superlux CP818 Microphone Impedance Matching Transformer

Product Description
The Superlux CP818 is a professional passive inline impedance matching transformer designed to connect low-impedance microphones to high-impedance inputs. It is the ideal solution for connecting balanced dynamic microphones to guitar amplifiers, PA systems, portable recorders, or older mixers with High-Z (Hi-Z) inputs. Equipped with a high-quality internal transformer, it ensures maximum signal transfer and prevents high-frequency loss over long cable runs without introducing unwanted hum or noise.
Key Features
• Passive design: Operates entirely without batteries or external power.
• Signal integrity: Preserves a full frequency response with minimal distortion.
• Durable construction: Rugged, metal-shielded casing built for road use and daily studio handling.
