PHONO box contents include the following:

1 (one) – PHONO Preamplifier
1 (one) – PHONO User’s Guide
1 (one) – Power cord [6.6’ – 2 meters long]

Carefully unpack each piece and check for shipping damage. If there is any damage, or if anything is missing,
please contact your dealer, distributor or Bel Canto Design. Save all packing materials as they are specially
designed to protect the unit during transportation or shipping. If the packing becomes lost or damaged, please
contact your dealer, distributor or Bel Canto before attempting to transport your unit.

The power supply on the PHONO is preset for the proper power voltage. The power cable should have the
correct plug for your local power system. If you believe this to not be true, please contact your dealer immediately.

This product, like any electrical component, can be dangerous and cause injury unless correct handling
procedures are observed and used. Before powering this product, it is necessary to read and follow proper setup
and procedures.

Because the PHONO runs cool, it can be placed in many system locations without compromise. We do not
recommend placing weights or other objects directly on the PHONO. This may scratch or mar the chassis finish.
Do not use harsh chemicals when cleaning the outside of your PHONO.

Single Ended RCA inputs and RCA and XLR outputs are available. You can place the PHONO close to the
turntable and minimize the length of the low-level interconnect from your cartridge. When power is applied, the
front panel green LED will light.

IMPORTANT!

Make all connections
before powering your
unit!

• IEC power cord jack: Connect the supplied or a quality aftermarket power cord from this jack. Note the
power setting indicated on the back of the unit before connecting the power

• Ground: If your turntable has a grounding wire, try connecting it to this post. In many but not all cases,
this will eliminate the electrical hum that may be present in your signal

• XLR and RCA Outputs: Connect from these outputs to either a line stage Preamplifier or the analog input
of your DAC

• Dip Switches for Gain and Resistive Loading: Your cartridge manufacturer will recommend a certain load
which may require adjusting these settings. Refer to the following pages to adjust settings.

• RCA Inputs: Connect from your turntable

The sonic performance of the PHONO will begin to stabilize after 100 hours of continuous power up. We
recommend leaving the PHONO powered on at all times as it benefits the overall sound quality and draws little
power. If your system will not be used for an extended period of time, such as two weeks, or if there is an
imminent electrical storm, we recommend shutting off your system.

Switch Settings

A set of 6 switches are located next to each RCA input. These are used to setup the optimum Gain, Resistive
Load, and Capacitive Load for your cartridge. Please refer to your cartridge manual for the optimum gain and RC
loading recommendations.

Note that you should MUTE your line stage
Preampilfier or analog input on your DAC and turn
the PHONO OFF before making any changes to the
rear panel switches.

We recommend using a small flat tip screwdriver such as used for attaching your cartridge to a tonearm or a
similar tool to gently change the switch positions.

Gain Setting Switches

The PHONO default gain setting will be for typical high output cartridges, from 3mV to 5mV nominal output levels
the 38 dB gain setting will be best. If you are using a low output 0.3mV Moving Coil cartridge, switch each channel
to the 60 dB setting by pressing the Gain Switches to the DOWN position. The interim positions can be used to
optimize setup for different cartridge and preamplifier sensitivities.

Ensure that you MUTE your line stage Preampilfier
or analog input on your DAC and turn the PHONO
OFF before changing this setting to prevent a large
transient from damaging your loudspeakers or
power amplifiers!

Input Resistor Load Setting Switches

The default input resistance is 47,000 (47K) ohms when all switches are in the UP position. When a switch is set
in the DOWN position the corresponding resistor value is placed in parallel to the 47K resistor, resulting in a lower
input resistance. This means that a large range of effective input resistance values can be selected by selecting
different parallel combinations of resistance value. The table on the following page can be used to determine the
switch positions for different input resistance values.

NOTE: Both channels have the same switch settings! The 2nd Switch next to the gain switch is not used
and can remain in the UP position.

Refer to these charts when adjusting the dip switches.
