Description

SPL Lundahl Transformer (IN) Details
LL1540 is a high impedance, high level line input transformer. The transformer consists of two coils, each with one primary and one secondary part separated by a electrostatic shield. The core is a high permeability mu-metal core, and the transformer is housed in a mu-metal can. Being a high impedance transformer, the LL1540 should normally be used in a series-series connection.

A good part of the "warmth" that is commonly associated with vintage gear comes from transformers. With transformers the low end and lower mids sound rounder, full-bodied with more punch. The top end gets a silky touch and benefits from improved presence without sounding boosted.

Reasons are reduced odd harmonics (which produce harsh top end impressions) and a slower characteristic compared to electronic stages which causes a more voluminous sound. We recommend transformers especially for vocals while electronic stages can be better for highest precision in signal transmission (transients), but in the end it's a question of personal taste, which mics are in use and so on.

Used in SPL preamps or channel strips, the input transformers add ca. 14dB (depending on the microphone) of gain. This must be added to the scaled values. The additional passive gain relieves the complete unit permanently at any gain level.

That's why the input transformer is more important in preamps, but to benefit from all possible sonic effects and full operational safety, both input and output should be equipped with transformers. If SPL preamps only offer an input transformer option, the simple reason is not enough space.
