Before you turn it on…

IMPORTANT!

The voltage selector switch and mains fuse is 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 IEC power cable.

If the product is to be used outside of the factory set region, please ensure the voltage selector switch (found on the rear or side panel) is set to the correct voltage for the new country/region and that the appropriate mains fuse is fitted in the pull-out fuse tray below the AC Mains input.

The correct mains fuse rating for the product is printed on the chassis (see ‘ Rear Panel Features’). Use only the same type and rating as specified for the product. Be advised that different operating voltages require the use of different types of line cord and attachment plugs. If you are unsure, please contact your Orange Dealer.

BEFORE USING YOUR AMPLIFIER

Always ensure the amp’s volume control(s) are set to zero before switching on the power to amplifier.

To prevent hum and electrical noise operate your amplifier and instruments as far away from other electronic devices (especially fluorescent and neon lamps) as possible as these generate extremely high levels of electronic noise.

SPEAKER OUTPUTS:

Make sure the correct speaker load is connected in one of the following configurations:
• 1 x 8 Ohm cabinet – Use either speaker output (rear panel).
• 2 x 8 Ohm cabinets – Use both speaker outputs (rear panel).
• 1 x 4 Ohm cabinet – Use either speaker output (rear panel).

IMPORTANT NOTES FOR CONNECTING SPEAKER CABINETS:
• Do not use two speaker cabinets of mismatched impedance!
• Do not connect a speaker load which is less than 4 Ohms!
• Always connect to a speaker cabinet(s) of suitable power handling!
• Only connect speakers using a quality dedicated Speakon connection. Never use an instrument cable!

Failure to observe these points may cause damage to both the amp and cabinet(s).

VENTILATION:

The little Bass Thing must remain sufficiently ventilated at all times. 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.

Compressor Footswitch

Connect a latching footswitch to engage or defeat the compression control

Volume

Adjusts the overall output volume level.

Compression

Controls the effect level of the on-board compression circuit. Adding compression can help to smooth out sound peaks and transients for a fatter, more rounded tone. The COMP. LED will react to your playing and glow red through the power light.

Treble

Controls the treble frequency band

Frequency

Selects the centre frequency of the corresponding CUT/BOOST control.

– / +
CUT/BOOST
Controls the level of the selected frequency with up to 18dB cut (-) or boost (+)

When a CUT/BOOST control is in the 12 o’clock/noon position, the response of the frequency band is flat with no cut or boost. Sweeping the corresponding FREQUENCY control will have no effect.
The frequency bands crossover to enable even more cut/boost if required. For example, if the HIGH MID and TREBLE frequency bands are both set to 550Hz, the effect of their CUT/BOOST controls is combined.

Middle

Controls the middle frequency band

Bass

Controls the bass frequency band 40-400Hz

Input

Use a quality shielded instrument cable to connect your instrument to the INPUT jack socket. The PAD switch (-6dB) selects the correct input level for instruments with active or passive pickups.

Pad Switch

The pad switch removes 6dB from the input sensitivity when using active basses.
