Graham Slee Jazz Club Switched EQ Phono Stage

The Jazz Club phono preamp, by Graham Slee will put new life into the sound of your old records, including 78s, early vinyl LPs and EPs.

It does so by restoring their original tonal balance - something a modern phono preamp cannot do. Jazz Club also has the correct tonal settings (RIAA) for newer records, meaning you only need this phono preamp for your entire record collection.

The Jazz Club stereo phono preamplifier stage is a legacy product, now superseded by the Revelation phono preamplifiers. It was intended to be retired along with the Era Gold V phono preamp upon which the Jazz Club is based. However, public demand for both these phono preamps is still high and Graham Slee therefore continue to manufacture and support them.

Simple 3-Stage EQ

As well as being a hi-fi turntable preamp, the Jazz Club features settings to equalise pre-RIAA records. This means you can enjoy all your records - not just old ones - because the Jazz Club stereo turntable preamp is a great sounding hi-fi turntable preamplifier.

After connecting it up to your turntable, amplifier and/or recording equipment, and plugging the power supply in, you will then need to set the switches to suit the record you are playing.

By setting the switches to their RIAA positions a modern stereo vinyl LP will be played with the correct EQ, and will give the right tonal balance.

When playing an older record you need to note its record label (its manufacturer's name), and look up the settings given in the information sheet EQ tables.

Cartridges

All stereo high output cartridges (moving magnet / high output moving coil / high output moving iron) can be used with the Jazz Club stereo turntable preamplifier, but you may wish to use a dedicated mono cartridge instead.

This requires a slightly more specialised setting up procedure: It is best to use a true mono cartridge with a single output and connect it to only one of the stereo inputs. The unused input should be shorted using a shorting plug (contact us for this). The mono switch should be switched up or down (not used in its centre off position) and that will place the mono signal on both outputs.
