1. Laney IS SERIES 1 12 33 VI Laney Introduction 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 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 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 GG series bass amplifier has undergone a thorough two stage pre delivery inspection involving actual play testing as well as tube burn in Tubes are one of the most important components in your2. signal present at this speaker connector varies depending upon the selected mode of operation for the power amplifier When the amp mode selector 1s set to Internal Sub this speakon receives a full range signal When the amp mode is set to Bi amp the Lo frequency signal is sent to this speaker the Hi signal is sent to the Internal Hi socket 90 The frequency of the active crossover is 150Hz anything above 150 is sent to the Hi socket anything below is sent to the Lo socket The level of the signal sent to Lo speaker is fixed When the amp mode selector is switched to Bridge this speakon should not be used Power amp mode switch This switch selects the mode of operation of the B2 B3 power amplifier section Three modes of operation are available Internal Sub Bi Amp and Internal only In Internal Sub mode the two onboard power amplifiers run in parallel supplying 750 watts RMS of full range signal to each of the two output connections 90 feeds the two 10 loudspeakers and 91 supplies the single 15 loudspeaker on the B3 or is used for connection of an external cabinet on the B2 In Bi amp mode the onboard active crossover splits the frequency response of the pre amplifier and sends any frequencies below 150Hz to the 15 Sub loudspeaker B3 only or 91 on the B2 model and anything above 150Hz to the two 10 loudspeakers In Internal only mode Only the two 10 loudspeakers are used No signal appears on the Sub Lo connector Descr
