Laney A1+ Manuel utilisateur

WELCOME

The A1 + is a dedicated 80 watt acoustic amplifier - designed to give the

acoustic guitar player the most authentic electric reproduction of an acoustic

instrument possible.

Capable of producing the wide variety of sparkling high, luscious mids and tone

full lows associated with high quality acoustic instruments.The A1+ is ideal for

the singer songwriter who demands outstanding performance for both guitar

and vocals.

The A1+ is a kick back style amp design, making it ideally suited to operate as

your main sound source on stage in a conventional position or up close and

personal kicked back as your stage monitor.The A1+ can also be mounted onto

a pole stand by using the provided top hat in the base of the unit, giving you

additional options.

The A1+ preamp houses two channels each containing everything we think

you'll need in order to get a

great sound.The driver

compliment consists of a specially developed 8” Bass Driver and a 1” Dome

Tweeter, ensuring that the natural acoustic tones your guitar produces will be

reproduced faithfully by the A1+.

The A1+ is finished in a stylish, textured Polyurethane coating and a foam fronted

metal grille creating a very stylish and rugged amplifier which will continue to look

good gig after gig,

Because the A1+ has been designed by gigging musicians we understand that it is

important to be able to rely on your amplifier and to make sure that's the case

every A1+ is extensively tested both electronically and by a player before it is

shipped out. We are happy that your A1+ will give you years of trouble free service.

All the features & controls are covered over the next few pages, please take time to

read this manual fully as it will allow you to get the very best from your amplifier,

read on, play and enjoy...

INTRODUCTION

Combi Socket (for use with either XLR or 6.3 Jack) is provided for connecting your instrument or

microphone. Only use good quality screened cable.

Engages an EQ pre-shape circuit to give a natural Mid cut, Bass & Treble Boost sound.

Lights when peak levels are reached.To give optimum levels adjust Gain(4) till the peak LED just illuminates

on the very loudest passages. (After adjusting the EQ it may be necessary to readjust Gain)

Controls the level of preamp gain on the channel.Turning this control clockwise will add more gain to your

guitar signal, use this in conjunction with Volume (13) to achieve the correct volume and gain level you

require.

Active Bass control allowing boost and cut of the low-frequency response of the pre-amplifier.To give

optimum levels adjust gain till the peak LED just illuminates on the very loudest passages.

Selects the mid-frequencies (200Hz to 9KHz) to be cut or boosted in conjunction with the paramid level

control (7)

Boosts or cuts the chosen frequency set by (6).To boost the chosen frequency turn the control clockwise,

to cut the chosen frequency turn anticlockwise.

FRONT PANEL CONTROLS

Active Treble control allowing boost or cut of the high frequency response of the pre-amplifier.

Anti-Feedback control can be switched in and out here and adjusted with (10) to eliminate the "body

resonance" feedback often associated with amplified acoustic guitars at high volume levels.

To eliminate "body resonance" feedback, switch the filter in with (9) and adjust this control until the body

resonation reduces; you should find a “sweet spot on” the control where it disappears.Turning further out of

the sweet spot will bring the resonation back up again.This setting will be the optimum for that particular

guitar but may need to be altered if you plug in another guitar.

Switches the phase of the signal from the amplifier.When you play any acoustic guitar the sound it produces is

a waveform, the same applies to an acoustic guitar plugged into an acoustic amplifier. It is not uncommon for

these two waveforms - which occur simultaneously, to be out of phase with each other.To a player who is sat

close to an amplifier this poses a small problem if the wave forms are out of phase as they are destructive to

each other and cancel each other out.This would cause the guitar to sound a little thin and lack-lustre.

Engaging the phase switch switches the phase of the amplified signal removing the problem of destructive

interference. However sometimes the low frequencies being in phase can cause acoustic feed back problems,

to avoid this try operating the phase reversal switch. Most times this will cure the problem.One thing to point

out is that the audience does not hear any phase problems as by the time the sound wave reaches them any

phase differences have been cancelled out naturally.

Mutes the amplifier. LED is flashing when muted.

Sets the overall listening volume of the amplifier.

Effects Control Set: See pages 8-9 for detail of their operation.

A 3.5mm Stereo line input for connection of a CD/MP3 player as a backing track. Control the level of the

input using the Level control (20).

Socket for connecting a pair of quality headphones.When in use, the internal loudspeaker is automatically

muted.

Lights when Phantom Power has been applied to Channel 2. (See rear panel controls).

When illuminated indicates that power is connected to the unit and it is ready to go.

(ALWAYS SWITCH OFF AND DISCONNECT THE POWER CORD WHEN NOT IN USE)

Mains Power Switch.

Power inlet socket. Connect to your power source. Make sure the specified voltage is correct for your country!

The main safety fuse for the unit is inside this drawer.

USE ONLY THE CORRECT SIZE AND RATING OF FUSE AS SPECIFIED ON THE PANEL.

Information area relating to the amplifier: Serial Number, Fuse Type & Rating etc

Voltage Selection 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. It is essential to ensure that the correct fuse is

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

IMPORTANT:

Turns on a phantom power supply to Channel 2 (CH2), LED (22) on the front panel is lit when ON.

(IMPORTANT: Only use for Microphones requiring Phantom Power!)

Connect a Laney FS2 footswitch here, FX Mute (Tip) & Master Mute (Ring).

(FX Mute & Master Mute front panel switches must be enabled before they can be operated from the footswitch).

FX SEND: Mono jack socket for connection to the input of an external FX unit.

FX RETURN: Mono jack socket for the connection of the output of an external FX unit.

FX LOOP SWITCH: Selects the FX Loop mode of operation:

-10dBu - For connection of FX units with a -10dBu nominal output level.As this is intended for devices with a lower

output level, this switch increases the gain of the FX Loop by 10dB.

0 dBu - For connection of FX units with a 0dBu nominal output level.

This socket provides a balanced output for direct injection of the amplifier signal into a PA System or Recording Device.

The signal is taken pre-master volume.

Line out socket, to connect to another power amp etc., line level signal is taken post master volume.

If a hum loop is experienced when other equipment is connected to the D.I. or the Line Out socket, use this switch to

reduce or remove it completely.

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 amplifier. Many products have large transient surges at turn on and off which

can cause damage to your speakers. By turning on your amplifier 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 amplifier and then turn off its power before turning off other equipment.

Cables: Always use good quality shielded cable for your instrument and small signal connections. Never use shielded

or microphone cable for any speaker connections as this will not be substantial enough to handle the amplifier load

and could cause damage to your amplifier system.

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 the general warning & information sheet).

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

The onboard digital effects have been custom designed by Laney to complement the A1+.

You have a choice of Reverb, Chorus, and Multi FX.

Reverb positions have a variety of decay times from Plate through Rooms to Hall. Chorus positions have a various of

Lengths/Delays & Multi FX have a different blend of Reverb/Chorus/Delay on each position.These all need to be tried in

conjunction with various Level Control settings to obtain your own unique sound.

Using the Send Control, your new sound can then be assigned fully to either Channel, or any split in between, external effects can

be applied in the same way.

To add to the versatility of the Send Control, a mix of internal & external effects can be blended and applied to each Channel to

give a much broader spectrum of sounds to choose from.

See the diagrams below/opposite for a visual explanation.
