Coleman Audio announces CA500EQ 4-band analog stereo equalizer

The Coleman Audio CA500EQ is a 4 band stereo equalizer. Instead of the usual Variable gain--fixed "Q" circuits which change the tonal value as the amplitude is adjusted the CA500 has variable gain--variable "Q" circuits to CA500EQ maintain the tonal balance as the amplitude is adjusted. The bandpass of each circuit remains relatively constant so that when the EQ is boosted or cut, the slope of the curve increases to emphasize only the sound you are looking for. So you don't need to use excessive EQ to achieve the effects you want. Level and frequency settings use stepped switching making repeatability accurate and easy.

The input level control allows adjustment of the audio signal before equalizing, to help prevent clipping, and the output level control to readjust the gain of the signal with equalization.

There is a hard bypass switch and a phase reverse switch on each channel. The EQ IN switch turns the entire equalizer on or off to easily compare the equalization changes.

The high pass filter is an 18db per octave low cut filter variable from 30hz to 300hz. The HP filter switch allows on/off control independent of the EQ in switch.

The stereo/mono switch allows the CA500 to become a mono EQ unit. The audio passes through the left channel first and then though the right channel doubling the EQ options.

The high frequencies (8Khz, 10Khz, 12Khz and 16Khz) can be switched between shelving or peak EQ with 10db of boost or cut in 2db discrete steps. The low frequencies (30hz, 60hz, 100hz, and 150hz) are shelving EQ with 10db of boost or cut in 2db discrete steps. T

he two mid bands are peak equalizers with frequencies overlapping by 1/2 octave and have up to 14db of boost or cut in 2db discrete steps.

The inputs & outputs are balanced on XLR connectors.

is this possibly the first time someone has put the high freq on the left of a panel?

There's also a company called Neve who's done this

This looks saweeet.

Considering who Coleman Audio is, this is basically an MCI eq, so is very exciting.

I don't care that the high end is on the left, or that the output levels are also on the left.

Perhaps this is a kosher device? ;-)

"The level and frequency settings use stepped switches making repetabliity easy."

So, this can serve as a mastering EQ?

How transparent is it? Any transformers?

From a tone point of view... probably. From a usability point of view... IMHO, no.

2dB steps is too much for mastering. 0.5 or 1dB cut or boost is more common. Small tweaks.

Clever but you can do it with any dual mono device. Doing it with a press of a button is quite cool though.

Yeah, would have been nice to have API 5500 style gain/cut circuit that can be changed for smaller moves. I guess if it sounds good we'll see people mod the gain controls.

There is a mastering version coming out that will have 1db steps on the Hi & Low frequencies & 1/2 db steps on the Mid 1 & Mid 2.
It will be at the winter NAMM 2018 show.
