Voltage selection

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 inlet 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 IEC 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 the 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 devices such as these generate extremely high levels of electronic noise.

Speaker output connections

Make sure the correct speaker is connected at all times during operation.
Do not connect to a speaker load which is less than 8 Ohms in total.
Always connect to a cabinet of an appropriate power rating/handling.
Never use two cabinets of different/mismatched impedance.
Only connect speakers using a quality dedicated speaker cable. Never use an instrument cable.
Never connect headphones to the speaker outputs.

If you are unsure, please contact your Orange dealer.

Heads

1 x 16 Ohm cabinet — Use the 16 Ω speaker jack socket (rear panel).

2 x 16 Ohm cabinets — Use both 8 Ω speaker jack sockets (rear panel).

1 x 8 Ohm cabinet — Use either 8 Ω speaker jack sockets (rear panel).

Combos

All Orange valve combos have an internal speaker load of 16 Ω and are connected to the amplifier’s 16 Ohm output at the factory. When using an extension cabinet, only ever connect a 16 Ω cabinet. To connect an extension cabinet to the combo, reconnect the internal speaker jack to either of the 8 Ohm speaker outputs, and connect a 16 Ohm extension cabinet to the other 8 Ohm speaker output. Ensure to reconnect the internal speaker to the 16 Ohm output when an extension cabinet is not attached.

Valves

When powering up, ensure the amplifier is set to the STBY position on the front panel for a minimum of two minutes prior to performance. This will prolong the life of the valves. The HT fuse(s) (rear panel) will blow in the event of output valve failure in order to protect the internal circuitry from damage. Orange recommends output valves are replaced in full matched sets. Orange models fitted with EL34 or 6550 valves will also benefit from a bias adjustment, which should only be undertaken by a qualified technician. When changing the HT fuse, gently push down on the fuse holder and turn anticlockwise to release the fuse.

AD30 — instructions for use

Front panel

1. Power

The jewel light will illuminate when the mains switch is set to ON. The Standby switch should be set to STANDBY prior to performance. Refer to ‘Before Using Your Amplifier’.

2. Standby

Selects between Standby and Play.

3. Channel switch

Switches between Channel One and Channel Two. This can be switched remotely via a footswitch connected to the rear panel. Channel Two has a tighter bass response, more mid range and slightly more gain than Channel One. If all EQ controls are turned fully anti-clockwise, no signal will be present.

4. Master volume

Adjusts the master volume.

5. Bass

Adjusts the low-end response.

6. Middle

Adjusts the mid-end response.

7. Treble

Adjusts the high-end response.

8. Gain

Adjusts the Gain level, increasing in saturation as the control is turned clockwise. With all EQ controls turned fully clockwise, maximum levels of overdrive will be achieved. Lower Gain settings produce cleaner tones and may require an increase in the Master volume to compensate. No signal will be present with the gain set to zero.

9. Input

Use a quality shielded instrument cable to connect your instrument to the Input jack socket.

Rear panel

1. Speaker outputs

Refer to ‘Before Using Your Amplifier’ for full speaker cabinet options. If you are unsure, please contact your Orange dealer.

2. Channel

Connect a latching footswitch (e.g. FS-1) to switch between channels remotely.

3. HT Fuses

This fuse will blow in the event of output valve failure. Replace this fuse only with the exact type and rating as printed on the chassis.

4. AC mains input and mains fuse

Refer to “Before Using Your Amplifier“. Connect the supplied IEC cable to the AC mains input. Ensure the Power switch is set to OFF before connecting the IEC cable. The mains fuse is located in the pull-out tray underneath the AC mains input. If the mains fuse blows, replace only with the exact rating for your region. If the mains fuse continues to blow, contact your Orange dealer.

5. Voltage selector switch

Refer to “Before Using Your Amplifier”
