Tegeler Audio MythEQ 500

The Tegeler Audio MythEQ 500 is a four-band API 500-series equalizer designed as a counterpart to the Classic EQP-1—where the EQP-1 leans warm and smooth, the MythEQ 500 works cleaner and more precisely while retaining the harmonic character of the Tegeler Audio transformer-based signal path. Each of the four bands—high shelf, upper mid bell, lower mid bell, and low shelf—offers six switchable frequency points with up to ±15 dB of boost or cut, and the Q is proportional to gain: the more boost or cut applied, the narrower the bell, keeping assertive moves focused rather than broad. Tegeler Audio’s own transformers run throughout the signal path, contributing the same low-end definition and high-frequency rounding found across the Tegeler Audio line even with the bands set flat. For Los Angeles mixing engineers who need a 500-series EQ capable of both surgical precision and musical shaping, the MythEQ 500 covers both without requiring a module swap.

Key Features

• Four independent filter bands — high shelf, upper midrange bell, lower midrange bell, and low shelf each offer six discrete frequency options, covering a wide range of tonal applications from air and presence to body, warmth, and low-end control.
• ±15 dB boost and cut range — a wide gain range on all four bands supports both subtle enhancement and aggressive frequency shaping within a single module.
• Proportional Q design — the bell bandwidth on both mid bands narrows automatically as boost or cut increases, producing focused, musical curves at moderate settings and tight, surgical results at the extremes without a separate Q control.
• Tegeler Audio in-house transformers — input and output transformers are integrated throughout the signal path, adding the harmonic saturation, tidier low end, and pleasantly rounded highs characteristic of the Tegeler Audio house sound regardless of EQ band activity.
• Clean-to-characterful range — designed as the complementary opposite to the EQP-1’s warm, Pultec-style curves, the MythEQ 500 operates cleanly at conservative settings and can push into assertive, biting territory at more aggressive gain levels—all within the same module.
• In/bypass toggle switch — a dedicated toggle switch places the unit in the signal path or bypasses it entirely for fast A/B comparison.
• API 500-series mono format — standard single-slot 500-series footprint for integration into any API-compatible lunchbox or rack system.
