ART DJ PRE II Phono Preamp with RIAA Equalization
What is RIAA equalization?
Couldnt help but ask how does RIAA eq affect analog media? After all, it has no DRM.
RIAA is only used on vinyl, ever hook up an old turntable up to a regular amp? You will notice a distinct lack of low freqencies and high frequencies seem exagerated. RIAA equalization makes it flat.The reason why it is done like this it to reduce hiss during playback, minimise grove damage by reducing the movement if the stylus during low frequencies and allow for reduced groove width which lets more music to fit on a record.

What is a good power source for this product?
A link to one of partsespress's power cords
A great power supply for this phono preamp, would be one designed for the Lepai 2020 amplifier. Part #129-077 or #129-078 would be excellent. I am using part#129-078 with great results. The bass is deeper and the highs are clearer. Also this set allows the power supply to be put on the floor away from sensitive audio components. I also added a ferrite core part #110-450 to the power cord to prevent EMI interference from traveling back to my system. These supplies have the correct plug for direct connection to the preamp.

Having better gain using this preamp, can I still go through my receiver's phono input?
If its labeled "phono" that means it is already an RIAA phono curve--you may get more gain, but the "slant" will be off if you use this preamp. I would use an AUX input. That is line level and "flat" EQ. I wish this was less complicated, but the end result will be worth it!!

will it work with moving coil cartridges?
This phono preamp appears to have gain and input matching specifications appropriate for use ONLY with MM (Moving Magnet) cartridges. One cannot merely assume that units such as this can provide the greater gain and different loading (input matching) required for successful operation with MC (Moving Coil) phono cartridges. While the RIAA equalization curve is, indeed, the same for any type of cartridge - whether MM, MC, or otherwise - playing LPs recorded to the RIAA standard (as the vast majority, except very early recordings done before the standard became universally accepted), the fact that the same equalization applies to both cartridges implies little to nothing about the suitability a preamp for operation with different types of phono transducers. This preamp is likely to be unable to produce a practically usable, reasonably noise- and distortion-free output from a Moving Coil cartridge sufficient to drive a line level input (e.g., AUX, CD, Tape, DVD, TV in, etc.) on most consumer-level contemporary preamps, basic- or integrated-amplifiers (i.e., most home stereos and home theater systems).

Is hum & noise in the specs the same as signal to noise ratio
Hi. Yes, you are interpreting that correctly.Cheers.
