Welcome
Dear Player,

• Thank you very much for purchasing your new Laney product and becoming part of the worldwide Laney family. Each and every Laney unit is designed and built with the utmost attention to care and detail, so I trust yours will give you many years of enjoyment.
• Laney products have a heritage which stretches back to 1967 when I first began building valve amplifiers in my parent’s garage.
• Since then we have moved on from strength to strength developing an extensive range of guitar, bass, public address, multi instrument and keyboard amplification products along with a list of Laney endorsees that includes some of the world’s most famous and respected musicians.
• At the same time we believe we have not lost sight of the reason Laney was founded in the first place – a dedication to building great sounding amplification for working musicians.
  Warm Regards,
  Lyndon Laney Chairman & Founder

Quick Start

Startup Procedure:

1. Ensure Power switch (e) is off.
2. Connect the power supply connector to the AH4X4 (d) and plug into a wall power socket.
3. Make sure the Level (b) and Volume control (c) are set to 0.
4. Connect your audio source to any of the available channels, the Aux input for example using a 3.5mm Mini-jack to mini-jack audio cable (not included).
5. Set power switch to 1 (e).
6. Increase Level (b) to 5, but make sure adjacent Peak Led doesn’t light. If it does, reduce Level slightly.
   Slowly increase Volume (c) to a safe and comfortable level.

Sample setup – Single AH4X4

Inputs

Your AH4X4 provides you with a choice of four dedicated input channels, two of which are stereo allowing up to 8 mono inputs.

1. CH1/CH2 MIC/LINE INPUT: Combi socket providing the flexibility to connect either an XLR or jack terminated cable. For improved noise performance, both inputs will accept a balanced signal, but will quite happily work with a single ended, unbalanced signal. For best results, always use a good quality instrument/mic cable.
   Phantom Power is available from the XLR Input only.

2. MIC LINE: Use to select required gain setup for your chosen input device.
   For low impedance dynamic microphones please use the MIC input settings. For LINE level devices such as keyboards, drum machines, signal processors or an instrument, switch to the LINE/Instrument setting. Phantom Power is available from the XLR Input only.

3. PEAK: A warning light to let you know that your signal is almost at the point of over-loading the input. Ideally, you don’t really want to see the Peak led light at all. Damage won’t occur to the amplifier, but audio quality may suffer.
   Peak illuminates constantly = possible distortion.

4. LEVEL: Use to set the optimal level for the input, but also to create a desired level balance with other channels. Adjust the Level control so the Peak Led lights only during the very highest peaks of the connected signal, then reduce the Level control slightly so the Peak led doesn’t light.

5. FX: When enabled, the channel signal is routed through the onboard FX processor. For more information, please page 7.

6. CH3/4 STEREO LINE INPUT: 2 x Unbalanced Jack sockets for connection of a stereo line level signal. Either input 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. Active instruments may also be connected here.

7. AUX IN: A convenient 3.5mm stereo jack input, perfect for adding a backing track to the mix from your MP3 player or phone.

8. Bluetooth: Keep things tidy and lose the wire by connecting your souce via a Bluetooth capable device.
   To enable the onboard Bluetooth receiver, press the ON button. Whilst searching, the adjacent Pair led will flash fast. Once a connection has been established, the Pair led will flash slowly. The range for a Bluetooth connection is approximately 10M.
   If you aren’t using Bluetooth, de-press the Bluetooth ON switch. This will reduce power consumption and prevent accidental pairing.
   Both Bluetooth and AUX inputs can be used simultaneously.
   (Please see the manufacturers documentation for your Bluetooth device for connection
   information).

9. FX TYPE: This control determines the amount of Delay or Reverb to be applied to CH1 and CH2 if FX switch (5) is enabled. The delay/reverb length will be increased as you turn the control away from the centre position for both modes.
   Don’t forget to enable CH1/CH2 FX switches and enable Master FX ON, if you want them to  be routed through the FX processor.

10. MASTER FX ON: Quickly switch FX on and off using this control. The adjacent LED with illuminate when the FX section is active. The FX can also be switched via a Laney FS1 foot-switch.
    Master FX switch (10) must be On for FX remote to function.

11. FX LEVEL: Fine tune the amount of FX applied to the signal using this control.

12. MODE SWITCH: This dual function switch allows you to select one of four pre-defined EQ curves allowing you to adjust the overall feel of your music. To toggle from one to the next simply press the switch momentarily. An adjacent led will clearly indicate what’s selected. The EQ setting will be stored in memory, ready for use next time.

13. Flat: General purpose EQ setting.

14. Bass: An increase in the low frequency content of your audio.

15. Loud: An increase in both low and high frequencies, with a slight mid cut.

16. Vocal: Decreases the amount of bass and emphasises the vocal content. Also ideal for outdoors If you press and hold the Mode switch (for around a second) the EQ leds reconfigure to indicate the available/remaining battery life. The battery meter will display for as long as you hold the switch.

17. For the most reliable battery level check, there shouldn’t be any sound from the speakers. This could be done by turning down input level, disconnecting/muting input signals or by turning the Master Volume (13) to minimum.

18. VOLUME: This is the master volume level control. It controls the level from the onboard speakers, Link Out and Sub Out. Always start with this turned to minimum.

Outputs

Audio feedback is caused when a loop occurs between a microphone or guitar pickup and the loudspeaker. Commonly caused by pointing a microphone at a speaker or simply by the two being too close. The result is an unpleasant screeching or whistling sound. The AH4X4 is equipped to deal with this.

14. ANTI-FEEDBACK: When the Anti-Feedback control enabled, (the adjacent LED will illuminate) the AH4X4 actively and automatically searches for any signs of feedback (over multiple frequencies) and eliminates it before it becomes a serious problem.
    If you have microphones connected, enable the Anti-Feedback.

15. POWER MODE: The AH4X4 comes equipped with two power modes; Normal and ECO mode.
    Normal mode gives the maximum output level, while ECO mode is designed to prolong battery life whilst slightly sacrificing a little output level. When powered via the provided DC power adaptor it is recommended to enable Normal power mode for best performance. Normal mode uses intelligent power switching to give you the loudest and best sound quality whilst also conserving battery life. In either power mode, the amplifier will enter a sleep state after a short period of inactivity to conserve battery life. While in this mode the amplifier is muted and the adjacent standby led illuminates. As soon as signal is detected at any of the channel 1-6 inputs, the amplifier will wake instantly without missing a beat.
    You may temporarily disable sleep mode by holding the Mode button ‘12′ in for one second whilst turning the power on. Four leds will illuminate then extinguish to confirm this is active. This mode will also temporarily disable the intelligent power switching and force the amplifier to follow the mode switch setting, regardless of audio level.

16. LINK OUT: Intended for connecting to the ‘Link In’ of a second AH4X4 unit. Also can be used to feed signal to another amplifier, a recorder or mixing desk.

17. LINK IN: Intended for connecting to the ‘Link Out’ of a second AH4X4 unit. Also could be used as an additional input for the AH4X4 amplifier stage. A line level signal is required here.
    Connecting a signal to the Link In disables the amplifier sleep function. See page 11 for connection information.

18. FX REMOTE: With the use of a one-way foot-switch (Laney FS-1 recommended) the internal effects can be switched on/off

19. SUB OUT: A dedicated output allowing you to connect a powered sub or bass amplifier.
    When a jack is plugged in to this socket, frequencies below 120Hz are removed from the onboard speakers giving more power for the mid and high frequencies. Frequencies below 120Hz are routed to the Sub Out for the sub amplifier to take care of.
    Onboard FX are also applied to this output. This is a line level output.

Batteries

The AH4X4 comes with two battery holders * allowing you to choose which best suits your needs. You can use either:

1. 3* Lithium-ion (Li-ion) 18650 protected, button top, cells.
   Constant high discharge rate recommended at 6A or above, with a 3AH or greater capacity for best life. We recommend quality, Self-resetting batteries with a high trip current. Please note, Lithium batteries must be the protected, button top type; unprotected cells must never be used in this product and could pose a severe fire risk.
   Lithium batteries are not all created equally, many are sub-standard with very low or inconsistent protection levels. Sub-standard batteries could affect the performance of the AH4x4, or reduce the run time, or both! In some circumstances, these sub-standard batteries may also trigger the batteries own protection circuit too early, making the AH4x4 appear to shutdown. Always use the best high quality batteries!

2. 8AA alkaline (LR6) or 8NiMH (CR6) cells. Most AA cells cannot provide the necessary power levels for constant full power use in normal mode and are best used in eco mode or at modest listening levels, or for vocals.

About the batteries:
The table below gives you an idea of the usage time for your battery choice. This is a guide only as battery life is determined by many factors.
