The Model 503 500 series EQ sports a very low distortion signature with minimal phase deviation. Perfect for tracking, mixing, or mastering the 503 is extremely clear and transparent. With a 24dB range on each band plus selectable frequency high and low pass filters, the 503 is an incredible tone shaper.
The 503 is a super quiet and transparent EQ that has been meticulously designed to minimize phase artifacts. It is a great complement to any studio recording chain, mix down or marstering process.
The three band EQ with a +/- 12 dBu cut or boost range provides plenty of power for subtle or drastic tone shaping.
Switchable filters with two ranges per filter. The HPF offers 50 Hz and 150 Hz options. The LPF filters at 5K or 10K.
The 503 features an incredible range of 10Hz to 50Khz. This ensures adjustments to the edges of the audible spectrum are not cut off prematurely.

CLEAN GAIN, HIGH HEADROOM
With the Dual Drive knobs set at INPUT around 25% and the OUTPUT around 75% with the PAD off, you will get a very clean and pristine sound. The distortion is very low with no added harmonics and there is a ton of headroom. This is a great starting position for those wanting a clean tube sound regardless of the microphone type.
TUBE HARMONICS AND COMPRESSION
With the Dual Drive knobs set to INPUT 75% and OUTPUT 25% with the PAD off, you will get tube harmonics and natural tube compression. This is a great place to start when using ribbon or dynamic mics that need a little harmonic color.
HEADROOM AND WARMTH
The 583E provides great sonic versatility. With the -20 dB pad engaged and the INPUT set to around 50% you will hear a rich roundness and warmth. With these settings the mid-range will move forward and the input headroom is increased as well.
FREQUENTLY ASKED QUESTIONS
This is a question that we are asked often and the answer is no. Yes there is a glowing vacuum tube in your 500 series module but it is a 9A type preamp tube. This is the same type used in the AKG C-12, Telefunken 251, etc. While these mics only have one section of the tube active, they also have less internal volume for the tube to cool and yet the surface temp of these mics never exceed room temperature. As long as you don’t block the venting that is already part of the 500 series power supply you will be just fine.
