Patented Digital IF analog FM tuner front end
24/96 digital outputs
High Dynamic Range 24/192 DAC analog section
RDS/RDBS Function
8 Digit Alphanumeric Green LED Display
10 Station Presets
The Bel Canto FM1 uses a patented analog FM receiver architecture, the FM1 delivers superior RF performance
and interference rejection through the use of digital IF processing. The FM1 includes advanced seek algorithms,
adjustable soft mute, auto-calibrated digital tuning, and FM stereo processing. The FM1 utilizes digital processing
to achieve high fidelity and optimal performance, providing excellent pilot rejection, selectivity, and unmatched
audio performance. This DSP approach also ensures zero drift and optimum performance for the life of the
product. The advanced digital IF section operates at 24 bit 48 Ks/s data rate. This digital output can be interfaced
to a Bel Canto DAC product for D/A conversion or is converted to analog using the internal High Dynamic Range
Bel Canto DAC architecture. The FM1 uses Bel Canto’s Ultra-Clock low jitter clock and 122dB dynamic range
DAC to deliver superb analog output performance.
The FM1 also incorporates a digital processor for the European Radio Data System (RDS) and the North
American Radio Broadcast Data System (RBDS). Using this feature, the FM1 enables broadcast data such as
station identification and song name to be displayed on the 8 digit alphanumeric display. The FM1 provides
unprecedented functionality and performance in a compact easy to use package and is a perfect complement to a
complete Bel Canto DAC or Preamp based system.
The FM1 should be set for correct operation for European, North American and Japanese FM standards. The
internal setting is indicated by the presence of a suffix on the Firmware Rev number: U for USA, E for European
and J for Japanese settings. If your tuner setting does not match your region, both tuner operation and
performance will be seriously affected. If you do not have the correct region code, please contact your Bel Canto
Dealer or Distributor.
Front Panel Control Knob:
The control knob is a continuously rotating control with a push-switch function. Always push the button with your
finger in the direct center of the knob.
Rotate the knob to tune up or down the FM dial. Note that inter-station noise will be muted. Only stations with
signals above the mute threshold will be present.
Pushing the knob will switch between three different display modes:
01. FM or Preset, whether the signal is in stereo (M for Mono, B for Blend and S for Stereo), and the station
call number.
02. RDB/RDBS Display
03. RSSI Display in dBuV: Values above 40dBuV will result in full stereo separation.
Upon Power Up:
When switched on, the FM1 will perform its startup sequence followed by displaying the firmware revision. The
FM1 will be set for one particular world region, notated by one of three letters after the firmware revision: U for
US, E for Europe, J for Japan.
Display Modes:
The FM1 will then go to Standard mode. This displays either FM or the Preset number on the left, presence of
the stereo carrier, whether the signal is in stereo (S for full stereo, B for stereo blend, and M for mono signal), and
the tuned frequency. The decimal to the right of the FM or Preset display indicates the presence of the Stereo
Carrier on the station. This character will flash R if that station is transmitting RDS. Rotate the control knob to
discreetly select the frequency.
standard display mode, non-preset
The sonic performance of the FM1 will begin to stabilize after 100 hours of continuous power up.
Tuner: To access all functions of the Tuner, this button
must be selected
Mute (remote only): The FM1 is a fixed output device.
The Mute button will punch through to your Bel Canto
Presets: The FM1 can have up to 10 presets which are
noted as P0 – P9 on the display. To program each preset,
hold the number button on the remote for 2 seconds while
tuned in to the desired frequency. (For Preset 1, hold the
1 button, etc). To recall the preset, simply press the
number button again.
Display: Toggles through several display options:
Standard: displays FM or Preset number on the left,
whether the signal is in stereo (S for full stereo, B for
stereo blend, and M for mono signal), and the tuned
frequency. This character will flash R if that station
is transmitting RDS.
RDS Mode: Radio Data Signal, when available, this
scrolls station, song, and/or artist across the display.
Note that RDS screen will show NO RDS until RDS
data is received from the station (indicated by the
flashing R.) The RDS function is entirely the station
sending the RDS data. Sometimes this data is not
present from a given station.
There are 2 modes of RDS/RDBS function:
1) Radio Text: this is the first RDS screen in the
display rotation. When there is no data then NO RT
will be displayed.
2) Program Services: this is the second RDS screen
in the display rotation. When there is no data then
NO PS will be displayed.
Depending on the radio station, there may be similar
or quite different information displayed in each case.
Note that the RT scrolls and the PS are displayed in
8 character segments.
RSSI: Received Signal Strength Indicator, on a
scale of 1-100, over 40 is necessary for a good
stereo signal. Less than 40 will be a stereo blend
(B) or mono (M) signal.

The quality of your FM Antenna and the location and connection of the antenna are critical to the quality of the audio that you
will get from any FM tuner. The supplied antenna wire is only intended as a quick way to check the correct hookup and
operation of the FM1 but should NOT be used for critical evaluation of the FM1 performance. It is important that you work
with your dealer in choosing and setting up the correct 75 ohm FM antenna for your reception area and needs.
There are 3 points to pay attention to:
1) Choose the best FM only antenna that you can afford and accommodate in your location. Good results can be had
in urban areas using a directional indoor antenna but in rural areas were station strength may be low it could well be
necessary to install a good quality Yagi directional antenna that is sited to receive your favorite radio stations. There
are many sources of good FM antennas for example: has a good selection of both
indoor and outdoor antennas that should work well. Beware of the cheap ‘active’ gain antennas from various sources
as they often just add noise and distortion to the signal and do not really improve reception.
2) Use the correct 75 ohm coaxial cabling to connect from the antenna to the FM1. RG6 type coax is the best for
cable runs over 75-100 feet while RG59/U type cable can be used for shorter runs. In any case make sure that the
terminations and connections are clean and tight for reliable operation.
3) Any outdoor antenna should be installed by a professional to make sure that the correct safety precautions are
taken to protect you and your equipment.
Besides the included power supply, the FM1 may be powered by either the VBS1 or the LNS1. If using
the VBS1, please refer to the VBS1 User’s Guide for connectivity. If using the LNS1, please read the
The LNS1 is designed to power Bel Canto VB equipped products only. Use of any cable other than the
supplied power interconnect may damage either the LNS1 or VB equipped unit and will void any
warranty. Certain non-VB equipped units can be factory upgraded. To begin the upgrade process, fill out
the RMA form in the Support Section of our website
When connecting your VB unit to the LNS1, be careful to observe the alignment notches on both units
power receptacles and the power interconnect cable
When inserting the power interconnect cable, align the notch on the cable end and the alignment teeth on
the outer sleeve to the 12 o’clock position. This will allow the interconnect cable to fully seat and ensure
that the plug mates correctly with the power receptacle
Once the power interconnect cable is fully seated in the receptacle, lock in the power interconnect cable
by turning the outer sleeve clockwise one quarter turn. Proper seating of the LNS1 cable will ensure safe
and secure operation of the LNS1 and all connected components
The LNS1 has been designed to run on non-regulated, non-filtered AC Mains. Usage of any additional
isolation or filtration from the AC Mains supply may compromise LNS1 performance
