Some user and press reviews:
Telsie S has quickly become our favorite EQ. It’s super easy and intuitive to control.
The top-end sounds better than anything we have heard from other EQs.
It truly makes anything shine.
We have used the Tells S on drums, vocals, acoustic and electric guitars and
on the masters bus - it kills on all of it.
This EQ is an exquisite sound-designing tool. We wouldn't want to work
without it anymore.

This is what really sets the Telsie S apart: the excellent basic sound of the original combined with new, additional possibilities. This is what I miss in plug-ins from other manufacturers that simulate the W295b but leave it at a pure simulation and thus also inherit all the weaknesses of the original. The Telsie S takes a different approach here. (…)
On one hand, the W295b filter has been simulated very well, but the new options that go beyond the W295b functionality enrich the plug-in enormously. For anyone who wants to make optimizations in the bus, in the master, or even in the mastering process itself, the Telsie S is exactly the right choice.

(…) even in its default state—using only the high-pass and low-pass filters—it immediately imparted a beautiful color to the sound. It felt like the missing piece of the puzzle.
Next, I emphasized the midrange at 1.5 kHz, a frequency range that quickly reveals whether an EQ is truly smooth.
I then used the harmonic drive linked to the per-band outputs to fill in some gaps in the track and give the song a nice, finished glow.
Finally, the track needed some refined high end, and once again I got there very quickly by using the Air function on the last band of the Telsie S, while setting the mid–high crossover to 20 kHz.
Wow—smooth as silk highs.
The Telsie S sounds absolutely gorgeous, I think I’ve found a new best friend.
Do yourself a favor and try the Telsie S for yourself—I simply love it.

Product Description:
The Telsie S is a three-band equalizer plug-in inspired by the legendary Siemens W295b — a discrete Class A design from the 1970s, long valued for its open, airy high frequencies and rich, authoritative low end.
Originally developed for the ARD (Association of German Public Broadcasters), Siemens mixing systems represented the pinnacle of German broadcast engineering at the time. These consoles succeeded the iconic V72 and V76 tube designs and introduced a new level of precision and reliability. Modules such as the V276 microphone preamp and the W295 series equalizers quickly became highly sought-after tools in professional studios.
Among the three versions — W295, W295a, and W295b — the W295b stands out as the most advanced design. While all models feature low and high shelf filters, the W295b uniquely adds a mid-band presence/absence filter, allowing for more refined tonal shaping. Its distinctive character, especially the smooth and “airy” top end, continues to make it a trusted choice among experienced engineers.
The Telsie S faithfully captures this sonic signature while extending its capabilities for modern production. Built on over two decades of hands-on experience servicing and integrating original Siemens units, it delivers the depth and musicality of the hardware without the limitations of aging components.
No noise. No maintenance. Just the unmistakable character of a classic equalizer — redefined for today’s workflow.
The Siemens W295b and Telsie S:
Faithful to the architecture of the original Siemens W295b, Telsie S is built around a classic three-band equalizer design, combining musical simplicity with precise control.
The low and high bands operate as smooth shelf filters, delivering broad tonal shaping with up to ±15 dB of gain. The low shelf is centered at 40 Hz, providing weight and depth, while the high shelf at 15 kHz adds clarity and air without harshness.
At the heart of the equalizer lies the mid-band presence/absence filter. Designed with peak characteristics, it offers six carefully selected center frequencies — 0.7 kHz, 1 kHz, 1.5 kHz, 2.3 kHz, 3.5 kHz, and 5.6 kHz — allowing for precise control over presence and tonal balance. With up to ±8 dB of boost or cut, it enables both subtle refinement and more pronounced shaping.
The mid-band features a proportional Q design, where the bandwidth naturally narrows as gain is increased. This results in smooth, musical adjustments that remain controlled even at more extreme settings.
The additional benefits of the Telsie S plug-in
Extended Low-Frequency Control
While staying true to the original design, Telsie S expands the capabilities of the low band to offer greater flexibility in shaping the low end.
In addition to the classic 40 Hz low-shelf filter, the plug-in introduces a selection of peak filter frequencies at 40, 60, 100, 160, and 220 Hz. This allows for more precise control over bass and low-mid energy, enabling anything from subtle reinforcement to focused attenuation.
These peak filters feature a proportional Q characteristic, where the bandwidth narrows as gain is increased. The result is a more refined and controlled response, maintaining musicality even with more pronounced adjustments.
The added frequency options significantly extend the tonal range of the original unit, offering a level of detail and versatility suited to modern production environments.
Extended High-Frequency Control & AIR Enhancement:
The high band of Telsie S preserves the character of the original 15 kHz high-shelf filter — renowned for its smooth, open top end and effortless sense of air.
For increased flexibility, the plug-in also introduces two additional
peak filter options at 12 kHz and 14 kHz.
These provide more focused high-frequency shaping, with up to
±15 dB of gain in precise 3 dB steps, allowing for both delicate enhancement and more pronounced tonal adjustments.
The integrated AIR switch further extends the high-frequency
response, adding an elevated sense of openness and detail.
Its effect becomes even more apparent when working at higher
sample rates, offering an additional dimension of clarity and spatial definition.
Harmonics function:
Each band includes a dedicated harmonics stage:
Drive: Adds harmonic richness and saturation
Out: Compensates output level
Link switch: Controls whether Drive and Out are coupled
From subtle warmth to aggressive coloration, Telsie T gives you full control—while preserving clarity and musicality.
Low Cut/ High Pass and High Cut/Low Pass Filter:
Clean and shape your signal with:
Low Cut (High Pass) and High Cut (Low Pass) filters
Freely adjustable cutoff frequencies
Gentle –12 dB/octave slope
Perfect for removing rumble, taming harshness, and creating space in a mix.
X-OverS Low Band/Mid Band and Mid Band/High Band:
In the original analog W295b, the low and high bands feature extremely wide filter curves. As a result, adjustments at the 40 Hz shelf can influence frequencies up to around 2 kHz, while the 10 kHz peak band already affects content starting from approximately 200 Hz.
While this broad interaction is part of the classic sound, it can also lead to unintended processing of frequency areas that you may not want to affect.
This is exactly where the X-Over controls come into play.
They allow you to define the crossover points at which the three
EQ bands interact within Telsie S.
The default settings are 500 Hz (Low/Mid) and 7 kHz (Mid/High),
providing a balanced and musical starting point while keeping the
presence range clearly defined.
By adjusting these crossover points, you can reshape how each
band behaves across the spectrum and tailor the EQ response to
different mixing situations. For example, you can tighten the low band
to focus energy below 220 Hz for a stronger vocal foundation, or
reduce overlap by lowering the Low/Mid crossover.
Similarly, raising the Mid/High crossover allows you to boost high frequencies more precisely without unnecessarily affecting lower midrange content.
The Telsie S uses a carefully designed nonlinear filter topology for its crossover network, chosen for its musical and natural sound character. However, in multitrack situations—such as drum recordings—this design can introduce phase interactions between channels.
To address this, Telsie S includes a Linear Phase mode, which provides an alternative filter behavior with a more phase-linear response. This helps maintain phase coherence across complex, multi-microphone recordings and ensures a more transparent and controlled stereo image.
When Linear Phase is activated, the Low Cut and High Cut filters are automatically disabled to preserve the integrity of the phase-aligned processing.
This mode is ideal when maximum accuracy and phase consistency are required, while the standard mode remains the preferred choice for musical, analog-style coloration
This level of control makes it significantly easier to achieve focused, intentional EQ results across a wide range of sources.
We recommend exploring the included presets to quickly experience how powerful this feature can be.
Master Gain and Parameter Bar:
The Master Gain control is used to compensate for any level changes introduced by EQ processing or harmonic saturation. It ensures consistent output levels while shaping your sound. Clicking the control resets it instantly to 0 dB for quick A/B comparison.
The Parameter Bar provides a clear overview of all key settings at a glance. It displays the current values of the harmonic stages for each band—LBH (Low Band Harmonics), MBH (Mid Band Harmonics), and HBH (High Band Harmonics)—as well as the Low Cut and High Cut filter positions, both crossover frequencies, and the Master Gain level.
This gives you full transparency and precise control over the entire signal path at all times.
