Drop a PEX-500VIN "Vintage Edition" all discrete equalizer into your API 500 Series compatible rack and you're in for a real sonic treat. Built around a classic Pultec parametric EQ design, the PEX-500VIN gives you the open mids, creamy highs, and punchy lows that only a true passive equalizer can deliver. Like the classic EQs it was modeled after, the PEX-500VIN features all discrete circuitry, including transformer-coupled balanced inputs and outputs. A series of 3-step switches provide hassle-free control over your low- and high-frequency EQ bands plus the cutoff frequency for the high-frequency attenuator and our true-bypass circuitry keeps your signal pure on the rare occasions you actually feel like bypassing your PEX-500VIN equalizer.
