Audio Line Matching Transformers
The purpose of this Transformer is to match the Impedance of the loudspeaker or a number of loudspeakers to the optimum load of the tube or transistor. In other words, the transformer transforms the Impedance of the speaker, so that the impedance which it presents to the primary winding is equal to the load of the Output stage active element (tube to transistor).
- Dual Outputs: 4 & 8 Ohms.
- Maximum Ambient Temperature: 40 deg C.
- Frequency Response: 40Hz to 20,000Hz (-2dB).
- Connections: 150 +/- 10mm multi stranded PVC wire. Stripped and Tinned.
