Laney NEXUS-SL - Manual (Page 15)

Phones: Stereo jack is provided which can be used for headphones or a stereo feed to a PA system. There is a source switch
which can be set to listen to the full amplifier or the stereo return from the USB. A level control is included for comfortable
listening.
Tip:(Ensure the level is turned down before using to avoid unexpected excessive volume levels)
Auxiliary Input: This input allows the connection of backing tracks etc. to be mixed in post the FX loop.
It has a level control to aid mixing balance. This input is unaffected by the Mute control but is silenced by the Standby switch.
Fan: Built in automatic fan cooling. When the unit is first turned on, the fan will operate for a few seconds as a safety check.
FX Loop: This is an insert type loop so all of the signal is passed to the external processor. The mixing of the dry and effect
signal must be controlled in your external processor. A switch is provided to allow two nominal levels of loop signal and a bypass
option.
Tip: The internal FX operate prior to the external FX loop.
Tuner/ RAW: The output jack sends an untreated/dry signal to a tuner or DAW system. This output is unaffected by the Mute
or Standby functions.
Remote: A 5pin DIN connector is provided for connecting the Laney FS4-NSL footswitch. The functions controlled are Mute,
Pre-shape, Interval and Space.
Impedance selector switch: Used to select the optimum load impedance matching. It should be set to match the total load of
the Master speaker output socket. This ensures optimum operation of “Touch” panel control. Incorrect setting will not cause
damage or reduced power but your potential sound quality may be compromised.
Speaker Connectors: These connectors are independently coupled to two separate internal power amplifiers. One or both
can be used at the same time. When using only one output connector always use the “Master” one. This will ensure all panel
controls are fully functional and the best sounds are achieved. The Slave output socket tracks exactly the Master output.
The minimum recommended load on each socket is 4 Ohms. Speakon connectors are advised for connecting your cabinets but
¼” speaker jacks and cable can be used. (Do not use microphone or instrument cables). The maximum output available at each
socket is ~70Volts Peak and 30Amps Peak.
Tip: Speakers connected to the Slave output and their impedance have no relevance to the impedance selection
switch.
Tip: This amplifier is safe to operate without any speakers connected. This enables use with only headphones or just
as a preamplifier within your DAW system.
