Tegeler Audio Vocal Leveler 500 Series Module

Simple control, high-quality sound

Vocal Leveler 500 makes music simple.You don’t want to spend hours writing automation or searching for the correct plug-in setting. You’re on the go but don’t want to miss the fantastic Tegeler sound.If this describes you, then our new Vocal Leveler is ideal for you! We took the Opto Compressor from our Vari Tube Recording Channel and converted it to smaller 500 formats for you. The input transformer, opto compressor, and FET properly translate the Tegeler sound to the 500 format. Our in-house transformers provide harmonic basic saturation from the start. The signal is then routed through our tried-and-true The Vocal Leveler is a classic optical compressor with no frills, a true opto circuit from the VTRC.

FET and gain reduction

Vocal Leveler: The FET refines the sound to be warm and tube-like. The Vocal Leveler is a traditional optical compressor with no extras.With only two knobs for gain reduction and output volume, you have all the parameters you need to get fast and convincing results. The connection feature and stepped potentiometers make it simple to analyze stereo signals and recall your settings. You may also modify the compressor’s reaction times with a toggle switch, preparing you for a wide range of recording or mixing scenarios.

Vocal Leveler 500, a Versatile Tool

The Vocal Leveler’s musical compression nature, which is typical of optical compressors, makes it a versatile dynamics tool useful for more than just voices. Bass, acoustic guitars, and other signals benefit greatly from its smooth, subtle compression. Even when pushed harder, the Vocal Leveler stays transparent and unobtrusive, providing ideal protection against overwhelming signal peaks while recording without compromising the microdynamics or character of your audio signal.

Achieving a polished and consistent vocal sound is a cornerstone of professional audio production, whether in recording studios, live sound environments, or broadcast settings. The Tegeler Audio Vocal Leveler 500 Series Module is designed specifically to address the challenges of vocal dynamics, providing a seamless and transparent compression that maintains the natural expression of the voice while ensuring it sits perfectly in the mix. For audio engineers and producers seeking a reliable and high-quality optical compressor that integrates effortlessly into their 500 series setup, this module offers the precision and musicality needed to elevate any vocal performance.

One of the primary reasons to choose the Tegeler Audio Vocal Leveler is its use of a 500 Single-Stream Optical Compressor. Unlike typical compressors that can introduce harsh artifacts or unnatural pumping, this optical design gently controls the dynamic range by responding smoothly to changes in input level. For the user, this means vocals are consistently clear and balanced without sounding “squashed” or over-processed. The optical compression ensures that subtle nuances in the vocal performance are preserved, delivering emotional impact and intelligibility in every take.

The frequency range of 20 Hz to 22,000 Hz covers the entire audible spectrum, ensuring that no detail is lost in the compression process. This broad range is crucial because it guarantees that the low-end warmth and high-end brightness of the vocal are both maintained, providing a full-bodied and natural sound. Coupled with a maximum input level of 20 dBu and an output level peaking at 21 dBu, the module accommodates strong vocal signals without distortion, preserving clarity even during intense performances. The input impedance of ≥ 2.4 kΩ and output impedance below 600 Ω ensure compatibility with a wide variety of microphones and preamps, minimizing signal loss and maintaining optimal audio fidelity.

With a dynamic range of 100 dB and the ability to reduce gain by up to -12 dB, the Vocal Leveler offers substantial control over the vocal signal’s dynamics. This wide dynamic range means that even the most subtle or aggressive vocal passages can be smoothed out effectively, providing a professional-level control that enhances mix clarity and balance. The unit operates on a +/-16 V voltage supply and conforms to the 500 series standard module size, making it an easy addition to existing 500 series racks and systems. Weighing only 540 grams, it is both compact and robust, ideal for studio and mobile setups.

The Tegeler Audio Vocal Leveler excels in a variety of use cases. In the recording studio, it acts as a trusted partner for vocal tracking and mixing, giving engineers the ability to tame peaks and bring out the best in the artist’s performance without losing emotional impact. In live sound environments, the module’s transparency and reliability help maintain vocal clarity amid challenging acoustic conditions. For broadcast and voice-over work, it ensures consistent levels and natural sound, reducing the need for extensive post-processing. Its single-channel design provides focused, high-quality compression tailored specifically for vocal applications.

In summary, the Tegeler Audio Vocal Leveler 500 Series Module is a premium optical compressor that combines technical excellence with musical sensitivity. It offers smooth, transparent compression that preserves the character of the voice while delivering professional-level control and reliability. Its wide frequency response, excellent dynamic range, and compatibility with standard 500 series racks make it an indispensable tool for audio professionals who demand the best from their vocal recordings. Investing in this module means investing in superior vocal sound quality that will stand out in any mix, giving you confidence that your vocal tracks are always perfectly leveled and sonically pleasing.
