FOUR STROKE SERIES USER MANUAL
V1.0
This apparatus must be connected to a mains socket outlet with a protective earthing connection.
The voltage selector switch and mains fuse are set at the factory for the country or region in which this
Orange product is intended to be sold. To prevent serious damage to the product, ensure that the rated AC
mains voltage indicated on the product's rear panel agrees with the mains voltage from your AC mains outlet
before connecting the supplied mains cord. Do not tamper with the voltage selector switch.
If the product is to be used outside of the factory-set region, contact Orange amplification.
The correct mains fuse rating for the product and region is printed on the chassis next to the AC mains
inlet.
Use only the type and rating specified for the product
.
The
4 Stroke
may be operated without a speaker connected. When using a speaker cabinet, make sure the
correct load (Ω) is connected. Failure to observe these points may cause damage to both the amp and
cabinet(s)! Speaker outputs are wired in parallel:
1 x 8 Ohm cabinet: Use either speaker output
2 x 8 Ohm cabinets: Use both speaker outputs
1 x 4 Ohm cabinet: Use either speaker output
Never use two speaker cabinets of mismatched impedance!
Never connect a speaker load which is less than 4 Ohms!
Always connect to a speaker load of suitable power handling:
o
One cabinet:
The cabinet’s power rating should be
at least
equal
to the amp’s output power.
o
Two cabinets:
Each cabinet should have a rating of
at least 50%
of the amp’s output power.
Never connect speakers using an instrument cable! Only use a quality dedicated speaker cable.
Under normal operating conditions, the amplifier may generate heat. During sustained periods at high
volume levels the internal fan will start operate and may be audible.
Do not obstruct the fan or the cooling
vents and install the unit with space around it to allow ventilation.
To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. Never place
liquids or vessels containing liquid on or near the amplifier.
