DESCRIPTION

The HERCHILD model 670 is our newest release and one of the products we are proudest of. A tube-based audio

compressor with a striking resemblance to one of the most famous compressors of all time, the Fairchild 670. After

years of research, development and new designs we are finally ready to release this beast to the public. While making

sure to capture all the lush sound and mystique of the original we were able to improve on several aspects and offer a

more reliable, more durable, modern version that will last you for decades to come. The HERCHILD Model 670

contains nothing less that 22 tubes and 9 transformers to achieve that indistinguishable, classic, triumphant sound that

we all know and love. The original intention of the his historical compressor was to be used in the cutting of lacquer

masters for vinyl albums, but it soon became an industry standard for getting that all enveloping sound that takes us to

another level. The Fairchild Model 670 is found on almost all of the classic releases in the 60´s and 70´s, defining the

sound of a generation…or two.

The grandaddy of all tube-based compressors had a relatively limited amount produced, somewhere between 500 and

1,000 units. Therefore, some 60 years later there are only a small amount that remain today. There are even fewer that

are totally usable as years have gone by since it´s late 1950´s introduction so many units aren´t exactly as they once

were. Maintenance is obligatory on a high-end piece like this and unfortunately, too many of them have simply been

neglected and aren´t up to their optimal specifications. This means an alternative is needed. And this is where the

HERCHILD Model 670 comes in, to once again offer that magic that only this compressor design can.

Our HERCHILD Model 670 offers a couple of new and ever so helpful features. The user now has immediate access

to the all important DC THRESHOLD. This control basically combines adjustments to the progressively developing

curved RATIO and the KNEE simultaneously through 4 different settings varying from a gentle slope to a more

pronounced and aggressive slope. This control really does put sound manipulation right at your finger tips as opposed

to the original´s out of reach and inconvenient screw adjuster. The other main addition is something no modern day

studio can be without, a side chain filter. With the SC FILTER on the HERCHILD Model 670 you have 4 different

frequencies to choose from: 50, 100, 200 and 350 Hz. Using this feature you now have lots more control over just how

much compression will be applied as you can make it less sensitive to the lower frequencies therefore allowing more

compression where you need it and for the track to stay powerful.

The HERCHILD Model 670 also has the AGC section to determine which mode it will work in. There are 4 modes of

operation to choose from: IND, LINK, LAT VERT & LAT VERT LINK. The IND & LINK modes are for normal stereo

operation. IND give you independent control for each channel while LINK, obviously, links the two channels operation

together and determines the compression applied on whichever channel is producing the most gain reduction at any

given moment, and this amount will be used for both channels. The LAT VERT mode is originally from the days of

using a cutting lathe to prepare vinyl records. It was crucial to carefully decide the depth and the width of the grooves,

so you had precise control over both aspects in this mode. Nowadays, people have discovered the advantages of

mixing and mastering with MID/SIDE processing as it allows you creative control over the center and side signals of a

stereo track separately. LAT VERT is the equivalent to MID/SIDE and when used properly it really gives you the

control to make your songs sound wider, deeper and more focused. And the last option is LAT VERT LINK and is again

for MID/SIDE processing but this time with the two channels linked together and controlled by taking the average from

the two channel´s settings to determine what the overall control will be.

Choose the correct voltage depending on the country where used. 110 V 0r 240 V. This is EXTREMELY important as a mistake

here could be disastrous.

Do not open. No user serviceable parts inside. Risk of shock. Please do NOT open!

There is an extra fuse included in the fuse holder. If needed replace the blown fuse with this one. If the problem persists get in

contact with your official repair service. Do NOT try to service it on your own.

Make sure to leave at least one unit of rack space above and below the unit to guarantee proper ventilation.

Tube replacement is possible from the outside. Opening the unit is not necessary and should not be done under any

circumstance. Very high voltage inside!

Big changes in temperature can be detrimental to the tubes and is best to avoid.
