Console-Grade Weight and Output Safety for Modern Digital Print Workflows
The SPL Model 2162 Lundahl Line Out Kit provides high-end studios with a hardware path to achieving the dense sonic weight, low-end cohesion, and harmonic complexity characteristic of classic large-format analog consoles. Modern electronic output balancing chips offer incredible speed and a completely transparent frequency response, but they can sometimes sound overly analytical or clinical when printed directly back into digital audio workstations (DAWs).
By installing the Lundahl output transformer, your final line-level signal is converted into a magnetic field before leaving the chassis, adding a subtle layer of musical, low-frequency saturation and transformer "iron" character. Compatible with a wide variety of legendary SPL hardware—including the Frontliner, Channel One, Track One, Kultube, and Goldmike Mk2—this upgrade adds analog authority to your master output stream.
Product Description
The Power of Custom-Wound Swedish Iron:
A major factor behind the thick, punchy sound of vintage hardware is the presence of high-quality audio transformers in the output stage. The Lundahl Line Output Transformer naturally introduces soft, pleasant low-order even harmonics when driven hard. This rounds off harsh digital spikes and squares away fast transients into a cohesive, radio-ready wave. Vocals, acoustic instruments, and drums sound more physically present in the soundstage, making it easier to lock tracks into a dense commercial mix.
Increased Output Headroom & Cable Driving Power:
When loaded into a compatible SPL signal path, the Lundahl transformer maximizes downstream power transfer. Boasting a very low output impedance and an optimized turns-ratio, it can drive exceptionally long balanced cable runs (up to hundreds of feet across multi-room facility installations) without experiencing high-frequency roll-off, level drop, or capacitive line loading. This ensures your analog signal arrives at your destination A/D converter or patchbay with its full fidelity and dynamic range completely intact.
True Galvanic Isolation & Total Studio Safety:
Beyond its rich analog tonal character, the Lundahl kit functions as an electronic shield for your studio backend. Because transformers transfer audio strictly via magnetic induction, there is no direct wire-to-wire electrical contact between your SPL hardware's internal circuitry and the outside world. This provides complete galvanic isolation, eliminating ground-loop hums, cross-talk buzz, and shielding delicate active solid-state chips from unexpected reverse power surges or phantom power mishaps down the line.
