What to do if activating the Lang Stereo Equalizer causes a significant drop in signal volume?
If activating the equalizer results in a large drop in signal volume, you are likely applying too much attenuation to your processed signal. Be careful when adjusting the settings.
How to fix strident and screechy sound with Lang Stereo Equalizer?
To soften a strident or screechy sound, apply a bit of HF Droop at 10, 15, or 20 kHz.
How to clear up sub sonic frequencies on Lang Stereo Equalizer?
To address excessive sub-sonic frequencies, use some LF Droop to cut at 20 or 50 Hz. This should help clear things up.
Why applying Cut and Boost has no effect on the signal on Lang Stereo Equalizer?
If applying Cut and Boost to the frequencies has no effect on the signal, ensure that the Lang PEQ-2 isn't in OUT mode.
What to do if the frequency range covered by the HF Boost is too wide on Lang Stereo Equalizer?
If the frequency range covered by the HF Boost is too wide, use the Bandwidth knob to control exactly how wide or narrow that adjustment needs to be.
What to do if the frequency range covered by the HF Boost is too small on Lang Stereo Equalizer?
If the frequency range covered by the HF Boost is too small, use the Bandwidth knob to adjust the bell curve of the Peak.

The LANG PEQ-2 Program Equalizer is a professional audio device designed to bring the classic, sought-after sound of vintage equalizers into modern studio environments. It aims to replicate the unique, enticing sonic character that engineers, producers, and musicians have long admired, often found in older, less reliable equipment. The PEQ-2 is presented as a brand-new, robust solution for achieving this vintage sound without the typical issues associated with used gear, offering problem-free, heavy-duty use for years of music production.
The PEQ-2 is a passive program equalizer, drawing inspiration from Western Electric patents, similar to the ubiquitous Pultec equalizers, but with distinct advantages. Its primary function is to shape the frequency response of audio signals, allowing for both boosting and cutting of specific frequency bands. The device is particularly noted for its "sharper, tighter response," making it well-suited for mix bus applications where precision is crucial.
A key feature of the PEQ-2 is its extensive frequency selection. It offers nearly twice as many frequency options as some comparable vintage units, providing 26 choices compared to 14. This expanded control allows for more nuanced and precise equalization. The low-frequency section is highly versatile, offering independent controls for both boosting and cutting at different frequencies. This capability is a significant departure from some vintage designs that might only allow boosting and cutting at the same frequency, or only boosting in the low end.
The high-frequency section includes a "High Peak Boost" with a completely variable Q (bandwidth) setting. This allows users to adjust the width of the boosted frequency band from "Sharp" to "Broad," catering to a wide range of tonal shaping needs. The maximum boost available in this section varies depending on the selected bandwidth setting, ensuring a smooth and natural response across all adjustments. Additionally, a "High Shelf Droop" (cut) is available for taming high frequencies.
To maintain unity gain after equalization, the PEQ-2 incorporates a high-quality Silicon Transistor Amplifier in the signal path. An adjustable trimmer screw, located on the front panel within the LANG logo, allows for fine-tuning of the output gain. The device also includes a bypass switch, enabling quick comparisons between the processed and unprocessed signals. For robust and noise-free signal integrity, the PEQ-2 is equipped with custom audio transformers at both the input and output stages.
The PEQ-2 is designed with a simple, clear, and easy-to-use layout, despite its capability for extreme audio processing. Its stepped controls are a significant advantage, providing easy recall of settings and facilitating precise matching when using two units for stereo applications. This makes it ideal for critical mixing and mastering tasks where consistent and repeatable results are essential.
The independent boost and droop (cut) controls for both high and low bands allow for creative and unique equalization curves. Users can experiment with boosting and cutting at the same or similar frequencies, which can produce exciting and complex sonic textures not possible with simpler designs. This flexibility encourages experimentation and can lead to the discovery of new ways to shape audio.
The low-frequency shelf boost offers 8 selectable frequencies: 20, 30, 40, 60, 80, 120, 160, and 240 Hz, with up to 16 dB of boost. The low-frequency shelf droop provides 4 frequencies: 25, 50, 100, and 200 Hz, with up to 18 dB of cut. This extensive control over the low end allows for precise sculpting of bass frequencies, from adding warmth and weight to cleaning up muddiness.
For high frequencies, the peak boost offers 8 selectable frequencies: 2.5, 3.75, 5, 7.5, 10, 12, 15, and 20 kHz. The boost level varies between 21 and 12.5 dB, depending on the bandwidth setting, ensuring a musical and natural sound. The high-frequency shelf droop provides 6 frequencies: 2.5, 5, 7.5, 10, 15, and 20 kHz, with up to 16 dB of cut. This comprehensive high-frequency control allows for adding air and presence, or taming harshness and sibilance.
The PEQ-2 is suitable for various applications, including bass recording, track insertion, mix bus processing, and mastering. Its ability to provide both subtle enhancements and dramatic tonal shifts makes it a versatile tool for any audio professional. The inclusion of input and output transformers ensures a powerful, solid, and noise-free signal, which is crucial in professional audio production.
The manual emphasizes the PEQ-2's design for "problem-free, heavy-duty use," suggesting a robust build quality intended for long-term reliability. While specific maintenance routines are not detailed, the use of high-quality components like custom inductors, tone capacitors, Silicon Transistor Amplifiers, and custom audio transformers implies a design focused on durability and consistent performance.
The device is designed to be powered by an external HA-PSU04 power supply, which helps to keep noise out of the main unit and simplifies power management. The use of standard XLR connectors for input and output ensures compatibility with professional audio setups and facilitates easy connection and disconnection.
Troubleshooting guidance is provided for common issues, such as the equalizer having no effect (check if it's in "OUT" mode), the HF Boost frequency range being too small or too wide (adjust the Bandwidth knob), a significant drop in signal volume when activating the equalizer (indicates excessive attenuation), or the sound being too strident or screechy (apply HF Droop). These tips help users quickly diagnose and resolve common operational problems, ensuring continuous and effective use of the device.
The PEQ-2 is backed by a limited 2-year warranty, covering defects in materials and workmanship. This warranty underscores the manufacturer's confidence in the product's quality and provides peace of mind for the purchaser. The warranty process involves delivering the product prepaid to Lang Electronics Inc. with proof of purchase, where it will be repaired or replaced at their option. This commitment to customer support and product longevity is a key aspect of the device's maintenance and ownership experience.
