2 pairs of speaker plugs
mains lead
warranty card
this manual
We recommend that you retain all packaging in case you need to transport the unit at
a later date.
Voltage Selection
Do not connect the mains supply until you have verified that the unit is set to
the correct voltage for your mains supply.
The unit is factory-set for a 230 volt mains supply and must not be connected
to a mains supply other than this before it is adjusted for your local voltage.
To set the voltage, use a screwdriver to adjust the voltage selector on the back
of the unit to the correct setting.
This unit must be earthed. Use the earthed moulded mains lead supplied.
Never use an unearthed plug or adaptor.
Positioning
Allow at least 10cm of space to the front, rear, sides and above the Linn 2250 power
amplifier. Do not block the ventilation grills on the front of the unit or the vents on
the sides, top and bottom.
The unit can be rack mounted in a 19” rack (Linn part No. RAKK-19/1).
Cleaning
Disconnect the Linn 2250 power amplifier from the power supply before cleaning.
Remove dust and fingerprints with a soft damp cloth. Avoid using domestic cleaning
products on the unit.
Inputs and Outputs
The unit has both unbalanced and balanced inputs, selected by a push-button switch
on the back panel. Use the appropriate push-button position to suit your choice of
preamplifier and cabling. The LEDs on the back panel will indicate which inputs are
selected. The push-button does not directly pass the audio signal but instead sends a
control signal to distortionless solid state switches. Both unbalanced and balanced
signals are passed through the unbalanced and balanced line out sockets to enable
daisy-chaining of amplifiers.
Back Panel
The Linn 2250 power amplifier should be powered down then disconnected
from the mains supply before connecting or disconnecting any of the plugs on
the back panel. If this is not done you may generate surges which could
damage the unit or other components in your AV system.
