SPL Lundahl Transformers

Sound
Transformers can be used as an alternative to electronic balancing stages in the inputs and outputs. The bass and fundamental range becomes rounder, fuller and gets more pressure, the high and overtone range sounds a bit silkier and more present.

Reasons are reduced portions of odd harmonics (which are responsible for hard high tone) and a certain inertia compared to electronic stages, which leads to the more voluminous low tone characteristics. However, electronic stages are better for highest precision and speed in signal transmission (transients). The bottom line: it’s a question of taste and application.

Operational Safety
When equipped with input and output transformers and completely symmetrical cabling, no voltages can enter the device via the signal connections that could cause damage. The signal transmission is inductive and thus electrically isolated. No hum is guaranteed. And last but not least, transformers drive very long cable runs, which is a welcome feature in live applications at the latest.

Ex works or retrofittable
All devices for which transformers are optionally available can be supplied ex works with transformer(s). Please inform your dealer if necessary, even if the device is not directly offered with a transformer option. Transformers can also be retrofitted, but only by SPL or authorized service partners.
