SNAXO Installation
3 SNAXO Installation
The SNAXO active crossovers are designed to provide optimised active filter characteristics
for all active-capable Naim loudspeakers. They should be mounted horizontally on an
equipment stand intended for the purpose. It is important to ensure that the stand is level.
SNAXO active crossovers contain no internal power supply and must be connected to a
dedicated Naim FlatCap, Hi-Cap or Supercap power supply.
The SNAXO 362BMR incorporates a suspension system to isolate its sensitive components
from vibrational energy. The suspension system is protected during shipping by two transit
screws. The transit screws must be removed before use. Once the transit screws are removed
the SNAXO must not be inverted. Transit screw removal is best carried out once the SNAXO is
installed in its final location and before connections are made.
3.1 SNAXO 362BMR Transit Screws
Two transit screws must be removed from the underside of the
SNAXO 362BMR before use and replaced if it is to be carried
any distance, packed or shipped. Transit screw removal is
illustrated in Diagram 3.2. SNAXO 362BMR transit screws must
not be used with any other Naim product.
Damage may result if the SNAXO 362BMR is inverted either
during or after transit screw removal.
To gain access to the transit screws, position one end of the
SNAXO 362BMR over the edge of a table, remove (or replace)
the screw that becomes accessible and then repeat with the
other end.

3.3 Connecting SNAXO
3.3.1 Power Supply
SNAXO active crossovers must be connected to a dedicated
Supercap, Hi-Cap or Flatcap power supply.
Connect the SNAXO to the dedicated power supply using, in
the case of a Hi-Cap or Flatcap, a Naim SNAIC interconnect
cable, and in the case of a Supercap, the appropriate Burndy
cable. In either case take care to connect with the correct cable
orientation.
Note:
If the SNAXO Burndy power supply socket is not used,
the supplied Burndy link plug must be inserted. Similarly, if the
SNAXO DIN power supply socket is not used the supplied dust
cover should be fitted.
3.3.2 Signal Input
To ensure the appropriate signal earthing arrangements, the
input signal to a SNAXO active crossover is delivered via its
power supply. The diagrams on the following pages illustrate
signal input connections.
3.3.3 Signal Outputs
SNAXO output signals are carried on 4-PIN DIN sockets. The
four or six output sockets should be connected to the power
amplifier input sockets as appropriate.
Each left and right filter output is available on two separate
DIN sockets to enable the use of both mono and stereo power
amplifiers.
Take care to ensure that SNAXO outputs and amplifier inputs
are correct with respect to loudspeaker drive units. Incorrect
connection may result in loudspeaker damage.
The diagrams on the following pages illustrate signal output
connections.
3.4 Output Level Adjustment
Filter output level adjustment is available via trim controls
within each SNAXO. When shipped the trim controls are set
nominally flat. Contact your retailer or local distributor for
information and advice on level adjustment.
