Gain Settings, Initial Setup, and Placement

• Gain Settings

Internal jumpers accommodate Moving Magnet, Moving Coil (Low Gain), and Moving Coil (High Gain) settings. The Phono1 is shipped from the factory set for Moving Magnet operation. Gain structure changes are easily made by first removing the two gold nuts from the RCA output jacks using a 5/8” socket. Take care not to scratch the chassis by avoiding contact between the socket and the end panel. Next, remove the four stainless steel screws securing the opposite end panel with a 7/64” Allen tool. Carefully slide the circuit board partly out by slowly pulling on the input side end panel while securely holding the chassis. The circuit board only needs to be slid out part way to gain access to the internal jumpers. There are a total of 6 blue jumpers, which are labeled on the circuit board in the following locations: J7, J4, J6, J11, J3, and J5. They are easily removed by pulling them off of the 2-pin headers. When replacing the jumpers, be sure the jumper is oriented with the characters ‘3M’ at the top, otherwise the jumper may not function.

MOVING MAGNET CARTRIDGE

When using a Moving Magnet cartridge, the jumpers in locations J4, J6, J3, and J5 need to be placed in the positions labeled ‘MM’ (40dB of gain at 1kHz). The two remaining jumpers in locations J7 and J11 are inactive with this setting, and their positions are therefore irrelevant.

MOVING COIL CARTRIDGE

When using a Moving Coil cartridge, the jumpers in locations J4, J6, J3, and J5 need to be placed in the positions labeled ‘MC’. If low gain (54dB at 1 kHz) is desired, place the jumpers in locations J2 and J11 in the positions labeled ‘LOW’. If high gain (60dB at 1 kHz) is desired, place the jumpers in locations J2 and J11 in the positions labeled ‘HIGH’.

Bel Canto recommends that you consult your turntable consultant / dealer to ascertain the exact setting to use with your particular system.

In the lack of specific system information the following can be used as a guide:

-Use the Hi gain/MC setting when the output of your cartridge has less than .5mv output.

-Use the Low gain/MC setting when your cartridge has more than .5mv output.

When set for Moving Coil, the externally accessible loading DIP switches located between the input jacks are active. Loading options range from 50 Ohms to 50K Ohms, and right and left channels are adjustable independently.

• Cartridge Loading

Cartridge loading settings should directly correspond to the cartridge manufacturers recommended loading figure. If you don’t know the recommended loading of your cartridge, please contact the manufacturer or your dealer for this information.

Loading settings can be done using the DIP switches seen through the opening near the RCA inputs of your phono stage. For the normal settings seen on the panel below the DIP switch opening use a pen or small pointed object to switch down the corresponding DIP switch. All other switches should be in the up position.

Note: Changes to the DIP switch positions only apply when the MM/MC jumpers, located inside the Phono1, are in the Moving Coil (MC) position.

Please refer to the following chart for a complete listing of loading settings possible to correctly match your cartridge:
