1. USER MANUAL Laney Congratulations on your decision to purchase a Laney amplifier Laney products are designed with ease of operation as a primary objective however to ensure you derive the best from your new amplifier it is important you take time to read this user manual and to familiarise yourself with the control functions and facilities available BEFORE SWITCHING ON After unpacking your amplifier check that it 1s 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 EARTH OR GROUND GREEN YELLOW NEUTRAL BLUE LIVE BROWN This manual has been written for easy access of information The front and rear panels of each unit 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 valve amplifier has undergone a thorough two stage pre delivery inspection involving actual play testing as well as valve burn in Valves are the most important component in your Laney valve amp However they are also the most fr2. 7 8 3 2 d 1 VOLUME 4 a 6 7 8 9 0 10 4 2 3 7 lt 8 2 8 i 1 0 10 VOLUME VOLUME a gt 6 7 8 9 0 10 MIDDLE 10 MIDDLE MIDDLE 10 MIDDLE MIDDLE 10 MIDDLE MIDDLE MIDDLE MIDDLE 10 MIDDLE TREBLE REVERB 10 10 TREBLE REVERB 10 10 TREBLE REVERB 3 A 1 Q7 o 0 10 TREBLE REVERB 10 TREBLE REVERB 10 TREBLE REVERB EFFECTS 5 fI 5 6 0 10 EFFECTS EFFECTS 0 10 EFFECTS EFFECTS 5 4 3 2 1 i 10 EFFECTS EFFECTS 5 4 3 2 1 o 10 EFFECTS EFFECTS 4 5 3 2 10 EFFECTS 7 8 9 CHANNEL CHANNEL 7 CHANNEL 7 CHANNEL 7 CHANNEL TRIODE PENTODE DAMPING TRIODE PENTODE DAMPING TRIODE PENTODE STANDBY POWER STANDBY POWER STANDBY A E DAMPING TRIODE POWER RUN E E PENTODE STANDBY a El DAMPING TRIODE POWER RUN E E PENTODE STANDBY O Y DAMPING POWER The above setting are examples only Many variations of these settings can be achieved using a combination of Pentode Triode and Damping settings Please experiment as much as possible when searching for your ideal tone Laney Model ChromeOzone POOP OP OOOO EOEOY Fah KEL co O PENTODE STANDBY DR ME VOW UME GAIN AONE MD DLE T BLE REVERB M DAMPING POWER x Explanation of terms LO INPUT This i

EXTENSION SPEAKER SOCKET This is the socket to which you should connect an 8 Ohm extension cabinet When an extension cabinet is connected the resultant impedance will be 4 Ohms and the speaker impedance switch should be set to 4 Ohms Mismatched impedance will reduce the amplifiers performance and in some cases may cause damage to your amplifier IMPEDANCE SELECTOR SWITCH This switches the internal impedance setting of the amplifier When using with the on board speaker set to 8 ohms When an 8 ohm extension cabinet is also connected set to 4 ohms INTERNAL SPEAKER SOCKET 1 4 output jack factory connected to the on board speaker With no extension cabinet connected ensure the impedance selector switch 24 is set to 8 ohms POWER AMP LINE IN This socket is provided to allow a signal to be fed directly to the power amplifier from either an effects unit or another pre amplifier Connection at this point disconnects the internal pre amplifier nominal level OdBu POWER AMP LINEOUT This socket provides an output from the pre amplifier post effects loop and may be used to drive other power amplifiers effects units or mixing desks nominal level 0dBu FOOTSWITCH SOCKET This is a 5 pin 180 DIN socket for connection of the dedicated footswitch FS4 as supplied with the amplifier The FS4 is a four way switch that facilitates remote operation of both channels and reverb RETURN LEVEL This control adjusts the signal level returning from an
