NXF Laney OPERATING INSTRUCTIONS 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.
NXF Laney OPERATING INSTRUCTIONS FET NXF USER TIPS & QUICK START Connecting up your rig:Check your amplifier is the correct working voltage for the area you are in. Ensure you use the earthed power cord supplied with your amplifier to connect to the power supply.Make sure the supply socket you are using is an earthed/grounded type. Ensure you connect your speakers to the appropriate impedance socket with good quality speaker cable and connectors before switching on your amplifier.

NXF Laney OPERATING INSTRUCTIONS NEXUS NXF FRONT / REAR PANEL FEATURES 1 2 3 4/5 6 7 8 9 FET 10 11 12 13 Input level meter: This 4 band display shows the level of signal going through the preamplifier. The ideal level is when the amber light is illuminated for most of your playing. Adjust the FET gain or Tube Level controls (depending on which channel you are using) to set the display correctly. This may need adjusting if any EQ controls are changed.
NXF Laney 14 15 16 17 18 19 20 FET 21 22 23 24 OPERATING INSTRUCTIONS Input Pad Switch: Press in to reduce the input sensitivity when using high output basses. The switch is illuminated when pressed in. FET Gain: Adjust in conjunction with the input level meter to nominally run the display with the amber light illuminated and the red light just occasionally illuminating on the loudest notes you play. This will give the optimum signal level through the preamplifier.
NXF Laney 25 26 27 28 29 FET 30 31 OPERATING INSTRUCTIONS Cut out: This is provided to protect the amplifier in place of a power fuse. In the unlikely event of it operating the button will protrude out farther than normal and can be re-set by pushing back in. It may take several seconds before it can be re-set. If it trips again check for possible causes: damaged tubes wrong speaker connections etc. Should this not cure the problem refer to a qualified technician.

Zin 1M Ohm 20mV-8Vrms Preamp Bar Graph Level Indicator: 4 led bargraph display with combined mute indicator and peak lights.
NXF Laney OPERATING INSTRUCTIONS NXF CONNECTIONS Mixer FET Speaker cabinets can be connected to both sockets at the same time, providing that the total impedance is a MINIMUM of 4 Ohms Speaker Cabinets: The Laney Nexus range of cabinets has been specially designed for use with this amplifier: NX810 4 Ohm NX410 8 Ohm NX115 8 Ohm Their power ratings and impedances have been carefully matched for optimum performance. Use of other cabinets may result in an inferior sound.
NXF Laney OPERATING INSTRUCTIONS Speaker Connectors: There are two parallel connected SpeakonTM/Jack combination sockets provided. The minimum total impedance load is 4 Ohms (see speaker connection details) It is very important to observe correct speaker matching and connection to avoid damage to your amplifier. When using SpeakonTM connectors they should be wired 1+ to the positive speaker terminal and 1- to the negative terminal 2+ and 2- are unused and not connected within the amplifier.

NXF Laney OPERATING INSTRUCTIONS To change a preamp tube: Switch off the unit and unplug from the mains supply. Wait for the tubes to cool down. The chassis needs to be removed from its wooden sleeve to allow changing of the preamp tubes, with reference to the diagram, this is easily achieved by: 1. Removing the two side handles (5) by unscrewing the six No 8x1" (3) & four M5x30mm (2) on each handle. Remove the metal bar away from the handle and then gently pull the plastic body out of its recess. 2.
