Introduction

Lundahl Transformers

The Swedish firm of Lundahl is recognized world wide for the superior sonic qualities of its hand made transformers. SPL has used Lundahl transformers for many years, typically for optional in- and output stages of various products. In the case of the Passeq, there is no question of whether solid state or transformer-based input and output stages are the better choice: Because of their excellent and similar sonic qualities, Lundahl transformers are a clear choice to complement to the Passeq’s EQ circuitry.

I/O transformers are classical analog components in many “vintage” machines. In addition to increased operational safety due to the isolation from incidental I/O electrical interference they offer, transformers also introduce their own element of sonic “warmth” that is today too often inadequately attributed solely to tube circuitry.

The sonic quality from Passeq’s Lundahl transformers may be described in comparison to straight electronic I/O circuitry as: Bass and fundamentals are rounder, fuller, and exhibit more “punch”, while higher frequencies and harmonics sound silkier and more present, yet without leaving the impression of being overly emphasized or singled out. Moreover, they add the subtle impression that mix elements are better localized.

The reasons for this are the tendency of transformers to reduce uneven harmonics (which often give the impression of harshness in a sonic canvas) and to act with some latency compared to electronically balanced stages. In particular, fundamentals and low frequencies benefit from this.

Other Features

XLR contacts from Switchcraft serve as In and Output connections, while controls and switches are from the manufacturers Elma and ALPS (including ALPS’ “Big Blue” with 41 steps). The internal, fully analog power supply features a generously proportioned toroidal transformer that offers switchable, 110-120 Volt/60 Hz or 220-240Volt/50 Hz functions.

Conclusion

The Passeq represents the most powerful passive EQ system to date and fulfills the highest expectations in all areas of audio processing, from recording through mixing to mastering.
