TH30 Owners Manual

Thank you for choosing Orange. You are now a member of the ‘Legendary British Guitar Amplifier’ owners club!

Since 1968, when the company was founded, Orange has been a pioneering force in the guitar amplification
industry. Today, with a team of the world’s finest amplifier engineers, Orange continues to push back the
boundaries of conventional tube amplifier design.

Our commitment to craftsmanship and quality control has allowed our amplifiers to stand the test of time, giving
their owners as much pleasure now, as the day they were bought. To maintain this level of excellence, each Orange
amplifier is put through many rigorous test procedures before leaving the factory.

The warmth, tonal quality and rich harmonics generated by a valve amplifier cannot be reproduced by ‘artificial’
means. Many guitarists have reached the same conclusion: neither the transistor nor microchip is a suitable
alternative to valve technology.

This booklet contains valuable technical and safety information Please take the time to read this manual as the
information may enhance the sound and performance of your amplifier.

We are confident that you will be delighted with your new purchase and that it will provide you with many years
of enjoyment.

Please ensure your amplifier is switched to the correct voltage for your country. If unsure please consult your dealer.

1. 2 OUTPUT TUBES/4 OUTPUT TUBES SWITCH The 2 Output Tubes/4 Output Tubes switch (found on rear of amplifier) removes two of the EL84 output

valves, when in the 2 OUTPUT TUBES position. This switch also takes care of the speaker impedance (in
the background), when in the 2 OUTPUT TUBES position. This means that the speaker impedance is
always as stated in the screen print, above each speaker output jack socket, regardless of the position
of this switch.

2. Speaker Outputs Connect the amplifier to a speaker cabinet of the correct impedance.
Connect 1 x 16ohm cabinet to the 16ohm speaker output jack socket.
Connect 1 x 8ohm cabinet to either of the 8ohm speaker output jack sockets.
Connect 2 x 16ohm cabinets to both of the 8ohm speaker output jack sockets.

3. FOOTSWITCH JACK SOCKET The footswitch jack socket (rear of amplifier) enables channel switching using any latching footswitch.

4. EFFECTS LOOP SEND AND RETURN The effects loop, send and return jack sockets are intended for use with outboard pedals or rack

equipment such as delay, reverb and chorus etc.
Effects such as wah

wah, fuzz, distortion etc, would probably be best placed between the guitar and

amplifier input! The effects loop is wired in series with the pre-amp signal and is completely valve driven!

5. HT Fuse

(T500MA) The high tension fuse, protects transformers and other circuitry from blowing in the event

of an output valve shorting. Please refer to the Technical Specification section for fuse ratings.
Please contact a qualified service technician if this fuse fails!

6. Mains Socket & Fuse Holder This is where your mains lead plugs in. Also the mains fuse is located here. Please refer to
the Technical Specification section for fuse ratings.
WARNING:

This amplifier shall be connected to a mains socket outlet with a protective earthing
connection.
WARNING:

Where the mains plug or appliance inlet is used as the disconnect device, the disconect

device shall remain readily opperable.

5. Volume Control

(dirty Channel) The volume control adjusts the output volume of the dirty channel.

High levels of volume will heavily overdrive the output stage!

6. Shape Control

(dirty Channel) The shape control adjusts between all midrange (zero) to all bass and treble and no midrange

(maximum), on the dirty channel.

7. Gain Control

(dirty Channel) The gain control adjusts the gain of the dirty channel.

High levels of gain will heavily overdrive the pre-amp and may sometimes be uncontrollable,
especially when used at high volume levels! This will be more apparent when used as a combo and may
cause howling.

8.

Treble Control (clean Channel) The treble control adjusts the treble response of the clean channel.

These two controls are slightly interactive, creating a wider tonal range!

9. Bass Control

(clean Channel) The bass control adjusts the bass response of the clean channel. It also decreases midrange response when

turned fully clockwise.

10. Volume Control

(clean Channel) The volume control adjusts the volume of the clean channel.High levels will overdrive the output stage in a

vintage manner!

Using Your Amplifier

IMPORTANT! Before connecting your amplifier to a power source, please check the following:

1. Ensure your speaker cabinet is connected to the correct impedance speaker output socket, (see Rear Panel, item 2), using a
good quality speaker cable. Do not use guitar leads.

2. Ensure that the voltage selector switch is set to the correct mains voltage, (see Rear Panel, item 5).

The output (HALF/STBY/FULL) switch (found next to the power switch on front of amplifier) runs the valves at a low plate voltage (reducing output power)
in the HALF position and at a higher plate voltage (increasing output power) in the FULL position. The middle position is the standby position.
Make sure that the HALF/STBY/FULL output switch is in the Standby (middle) position before switching the power switch to the ON position.
(This will maximise the life of your valves)..

If you are unsure about any of the above points please consult your local Orange supplier.

Using The TH30

IMPORTANT! Before connecting your amplifier to a power source, please check the following:

1. Ensure your speaker cabinet is connected to the correct impedance speaker output socket, (see Rear Panel, item 2). Always use a good quality speaker
cable, do not use guitar leads. Combo models will have it’s speaker attached).

2. Ensure that the voltage selector switch is set to the correct mains voltage, (see Rear Panel, item 5).
When powering up your amplifier, switch to the ensure the ‘Standby’ position is set from the front panel and then switch the power on from the rear panel,
two minutes before switching from 'Standby' to the ‘On’ position. (This will maximise the life of your valves)..
If you are unsure about any of the above points please consult your local Orange supplier.

Selecting Output / Number of Tubes
The output switch (found next to the power switch on front of amplifier) runs the valves at a low plate voltage (reducing output power) in the HALF
position and at a higher plate voltage (increasing output power) in the FULL position. The middle position is the standby position. This switch should be in
the standby position for around two minutes after first powering up the amplifier!
OUTPUT POWER COMBINATIONS.
Output switch HALF, 2 OUTPUT TUBES = 7watts.
Output switch HALF, 4 OUTPUT TUBES = 15watts.
Output switch FULL, 2 OUTPUT TUBES = 15watts.
Output switch FULL, 4 OUTPUT TUBES = 30watts.

Using The Dirty Channel
This channel features three controls, Gain, Shape and Master Volume. Loads of Gain level, however using the unique 'Shape' control will allow a vast array of
tones, from Classic Rock through to Scooped Metal.

Using Clean Channel
This channel features a classic Orange control section of Treble, Bass and Volume.

Using the Footswitch
The Switch on the front of the amp must be set to Dirty Channel for the footswitch to function. This feature ensures the user will always be able to switch
channels even if there is damage to the footswitch jack.

From time to time output and preamp valves may fail. Most users find regular valve
replacement to be of benefit to the general upkeep and reliability of their amplifier. We
suggest that you always have spare valves available as replacements in the event of a
valve failure. Every Orange Class AB Amplifier will require re-biasing when it’s output
valves are replaced. This may not be necessary if use the same brand of valves with a
similar manufacturers rating. If unsure you should have the bias checked. BIASING
SHOULD ALWAYS BE CARRIED OUT BY AN EXPERIENCED TECHNICIAN.
Your amplifier uses various fuses to protect your amplifier from inconsistent voltages. It
is highly recommended that you keep a supply of spare fuses in case of failure. For more
information on caring for your amplifier, visit the Orange website ­www.orangeamps.com Tubes, fuses, covers and other accessories for your Orange ampli­fier are available from our online store - www.orangeamps.com/shop
