API Audio 5500 Equalizer

The range control allows you to scale the gain steps of the EQ bands. By reducing the gain, you can make much finer, more surgical adjustments, which is particularly useful for mastering or subtle program shaping where standard steps might feel too aggressive.

Yes, it is designed for both. While the precise controls and range switch make it a staple for mastering, the classic API sound and robust build quality make it equally effective for tracking individual instruments or mixing.

No, the API 5500 features an integrated power supply. You can connect it directly to your AC power source using a standard power cable, keeping your rack setup clean and simple.

The true hardwire bypass ensures that when the EQ is switched out, the signal passes through the unit without any coloration or interference from the circuitry. This allows for an honest A/B comparison between your processed and unprocessed signal.

It is more of a character EQ than a transparent one. It utilizes discrete operational amplifiers and a transformer-coupled output, which adds a distinct, musical warmth and punch that many engineers rely on to glue a mix together.

The unit provides both XLR and 1/4-inch TRS inputs for flexibility, but you should only use one input source per channel at a time. It is designed to accommodate different studio setups rather than mixing multiple sources into a single channel.
