Choosing cartridge type

OPERATION

Select the cartridge being used by pressing the MM or MC button. The display shows current selection and the correct input sockets are automatically switched in.

RIAA and RIAA/IEC

This setting is common to both MM and MC cartridge types.

The -IEC option alters the normal RIAA frequency response by rolling off (reducing) the output at very low frequencies i.e. around 20Hz and below. See chart on P.11 for more information.

This can help to prevent distortion and/or overload of subsequent amplifier/speaker systems by low frequency artefacts such as record warp, surface noise or rumble.

Press the RIAA/IEC button to select IEC response. The display will indicate “IEC” to show that the IEC roll-off is implemented. Press RIAA/IEC button again to display “RIAA” and the output response is now without roll-off.

Cartridge - MM

IEC 47K 50pF

MM loading resistor selection

The load resistor for MM cartridge is selected by pressing MM-R button. There are two options available, 47K (47,000 ohms, or 47KΩ) or 68K.

Press the MM-R button to select 68K. Press MM-R button again to revert to 47K. Choose the option recommended by the cartridge manufacturer. If no recommendation is apparent, start by using the 47K option.

Cartridge - MM

RIAA 68K 50pF

MM loading capacitor selection

The load capacitor for MM cartridge is selected by pressing MM-C button. There are 8 options available, 50pF (pico-farads), 100pF, 150pF, 200pF, 250pF, 300pF, 350pF, 400pF.

Use the MM-C button to cycle through the options, until the closest one to the cartridge manufacturer’s recommendation is displayed. If no recommendation is apparent, start by using the 50pF option.

Cartridge - MM

RIAA 47K 400pF

MC loading resistor selection

The load resistor for MC cartridge is selected by pressing MC-R button. There are 10 options available, 10R (also written as 10Ω or 10 ohms), 18R, 25R, 50R, 100R, 200R, 400R, 800R, 1600R, or 47K (also written as 47,000 Ω or ohms).

Use the MC-R button to cycle through the options, until the closest one to the cartridge manufacturer’s recommendation is displayed. If no recommendation is apparent, start by using the 1600R option.

Cartridge - MC

RIAA 100R 470pF

There is a 47K setting in MC which is recommended for the higher output type MC cartridges giving out approx 1mV or more. If, however, connecting a high output MC cartridge to the MC input results in a excessively high sound output, it is perfectly in order to move it to the MM input and select input and loading options accordingly.

Note: The MC input capacitor is fixed and cannot be changed. This capacitor does not affect loading at such low impedances.

Trigger input and output

The unit can be triggered to switch on or off remotely by applying a ±4.5 to ±15V DC signal to the 3.5mm (⅛”) TRIGGER INPUT from an external triggering device. Any further devices to be triggered on/off may be connected to the TRIGGER OUTPUT jack as it replicates the TRIGGER INPUT signal. This will form a chain of devices that will switch on and off together. N.B. the on/off triggering action works from ANY device in the chain, whether at the beginning, middle or end of the chain.
