Laney AudioHub AH40 User manual

NOTE

This manual has been written for easy access of information. The

front and rear panels are graphically illustrated, with each control

and feature numbered. For a description of the function of each

control feature, simply check the number with the explanations

adjacent to each panel.

Your Laney amplifier has undergone a thorough two stage, pre-

delivery inspection, involving actual play testing.

When you first receive your Laney amplifier, follow these simple

procedures:

(i) Ensure that the amplifier is the correct voltage for the

country it is to be used in.

(ii) Connect your equipment with a high quality shielded cable.

You have probably spent considerable money on your amplifier

and equipment - don’t use poor quality cable, it won’t do your

gear justice.

Please retain your original carton and packaging so in the unlikely

event that some time in the future your amplifier should require

servicing you will be able to return it to your dealer securely

packed.

Care of your Laney amplifier will prolong it’s life.....and yours!

After unpacking your amplifier check that it is factory fitted with a

three pin ‘grounded’ (or earthed) plug. Before plugging into the

power supply ensure you are connecting to a grounded earth outlet.

If you should wish to change the factory fitted plug yourself, ensure

that the wiring convention applicable to the country where the

amplifier is to be used is strictly conformed to. As an example in

the United Kingdom the cable colour code for connections are as

follows.

INTRODUCTION

The Audiohub range of multi instrument amplifiers is designed to be the centre of your audio world. The portable AH40 and

AH80 amplifiers each feature 3 independent channels allowing connection of balanced XLR, line and Hi-

Impedance/Instruments, as well as a dedicated Aux In. The AH40 and AH80 are driven by 40W and 80W output sections

respectively. Additionally, the AH80 is equipped with a delay unit with Time and Feedback controls, and an FX send switch on

each channel.

Ideal for keyboards, vocals, electronic drums and playing recorded audio, the Audiohub series features custom drivers to

ensure that whatever sound source you use is produced and projected correctly and clearly. Add to this ‘Road Rugged’ solid

construction, carpet covering, metal grilles and specially designed kickback cabinets - the Audiohub Series is the ideal solution

for all of your audio performance and rehearsal needs.

AH40 FRONT PANEL

1. CH1 MIC INPUT Balanced XLR input for low impedance microphone signals (200-600 Ohms).

2. CH1 LINE INPUT Unbalanced Jack input socket for connection of all line level signals (keyboard, signal processor, sample, drum machine, etc.).

Note that the Mic and Line inputs may be used simultaneously, although it may be difficult to balance input levels, depending on your source.

3. CH1 LEVEL Adjusts the channel level, enabling the user to balance levels across channels.

4. CH2 STEREO LINE INPUT 2 x Unbalanced Jack sockets for connection of a stereo line signal. Sockets may also be used to connect a single

mono source, or two individual sources. When connecting independent sources, use the output controls on your device to adjust the balance between

the two signals.

5. CH2 LEVEL See CH 1 LEVEL.

6. CH3 LINE/INSTRUMENT INPUT Unbalanced high impedance input for connection of high impedance devices such as electric guitars/basses,

or regular line devices. This channel features +6dB gain compared to the other line inputs, so take care if connecting a line level device here.

7. CH3 LEVEL See CH1 LEVEL. As this channel has more gain than the other line inputs, don’t be surprised if you find that you need to set this

control lower than the others when using line level devices.

8. GRAPHIC EQ A 5-Band graphic equaliser to fine tune your sound and help eliminate feedback issues. This is applied to the master mix. EQ is

best used subtly. Cutting or boosting all bands, or using extreme settings can reduce clarity and dynamics.

9. MASTER VOLUME Sets the overall output level of the amplifier or headphones.

10. AUX INPUT 3.5mm Stereo Jack for connection of an auxiliary source such as an MP3 player. This input is controlled by the master volume

control. The graphic equaliser has no effect on the Aux input.

11. LINE OUT Balanced line output for recording or connection to another amplifier. This output is not affected by the equaliser or master volume.

The Aux input does not appear on this output. This allows you to record your performance without the presence of a backing track.

12. PHONES Stereo headphone socket. This disconnects the internal speaker so that you can practice by yourself. Ensure that the Master Volume is

turned down before plugging in your headphones.

13. POWER LED Indicates that the unit is powered on.

and Line inputs may be used simultaneously, although it may be difficult to balance input levels, depending on your source.

3. CH1 LEVEL Adjusts the channel level, enabling the user to balance levels across channels.

4. FX SEND When pushed in, this switch routes the channel signal to the built in digital delay.

5. CH2 STEREO LINE INPUT 2 x Unbalanced Jack sockets for connection of a stereo line signal. Sockets may also be used to connect a single mono source, or two

individual sources. When connecting independent sources, use the output controls on your device to adjust the balance between the two signals.

6. CH2 LEVEL & FX See CH 1 LEVEL & FX.

7. CH3 LINE/INSTRUMENT INPUT Unbalanced high impedance input for connection of high impedance devices such as electric guitars/basses, or regular line

devices. This channel features +6dB gain compared to the other line inputs, so take care if connecting a line level device here.

8. CH3 LEVEL & FX See CH1 LEVEL & FX. As this channel has more gain than the other line inputs, don’t be surprised if you find that you need to set this control

lower than the others when using line level devices.

9. DELAY TIME Controls the amount of time between repeats of the inbuilt delay. Turning this control clockwise will increase the delay time.

10. DELAY FEEDBACK This controls the amount of repeats in the inbuilt delay. Turning the control clockwise increases the amount of repeats.

11. DELAY LEVEL Controls the mix level of the inbuilt delay. Use the delay to add atmosphere to your sound, or to create interesting effects.

12. GRAPHIC EQ A 5-Band graphic equaliser to fine tune your sound and help eliminate feedback issues. This is applied to the master mix. EQ is best used subtly.

Cutting or boosting all bands, or using extreme settings can reduce clarity and dynamics.

13. MASTER VOLUME Sets the overall output level of the amplifier or headphones.

14. AUX INPUT 3.5mm Stereo Jack for connection of an auxiliary source such as an MP3 player. This input is controlled by the master volume control. The graphic

equaliser has no effect on the Aux input.

18. VOLTAGE SELECT SWITCH This is factory set to the correct voltage for the region the product is supplied to. If necessary it can be reset by

removing the mains lead and then loosening (but not removing) the screws securing the cover. The cover can then be pivoted away from the switch which

can be moved to select the alternate voltage. DO NOT reconnect the mains lead until the cover is replaced and secured. Please ensure the correct fuse is

fitted (as printed on the panel) for the voltage being used.

19. MAINS INLET SOCKET Connect to your power source using the supplied cable.

20. MAINS FUSE This drawer contains the main safety fuse for the unit. USE ONLY THE CORRECT SIZE AND RATING SPECIFIED ON THE PANEL.

21. MAINS POWER SWITCH When turned on, the Power LED on the front panel will light.

General Notes

Amplifier connection: In order to avoid damage, it is advisable to establish and follow a pattern for turning on and off your equipment. With all

system parts connected, turn on source equipment, tape decks, cd players, mixers, effects processors etc. BEFORE turning on your AUDIOHUB.

Many products have large transient surges at turn on and off which can cause damage to your speakers. By turning on your AUDIOHUB LAST and

making sure its Volume control is set to minimum any transients from other equipment will not reach your loudspeakers. Wait until all system

parts have stabilised; usually a couple of seconds. Similarly when turning off your system always turn down the Volume control on your

AUDIOHUB and then turn off its power before turning off other equipment.

Caution: These professional loudspeaker systems are capable of generating very high sound pressure levels. Use care with placement and

operation to avoid exposure to excessive levels that can cause permanent hearing damage. (Refer to guidelines on page 2)

Servicing: The user should not attempt to service these products. Refer all servicing to qualified service personnel.
