Description

Alphaton AT-Series audio transformers are precision manufactured to the needs of modern sound technology. AT- transformers combine compactness, high efficiency, ultra flat frequency response, good balancing properties, and very low distortion. 12 standard models from 150 ohms to 60 kohms, – 10 dBm to + 18 dBm help in nearly all situations a balancing or impedance matching problem arises. Split windings facilitate optimum impedance matching by connecting the windings either in series or in paralles configuration.

Selection and Ordering Criteria:

Please note: Connecting windings in series results in doubling the impedance; windings parallel in halving the nominal impedance of one winding. For example, the AT – 35 transformers’ primary windings of 300 ohm in parallel = 150 ohms, in series 600 ohms.
