NXT 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. If not using Nexus speakers ensure they are of sufficient power handling capacity and correct
impedance.
Quick start:-
Make sure the volume control is at minimum. The gain controls are at minimum. The EQ and graphic slider controls are at the
centre zero position and none of the push switches are illuminated. Turn your amplifier on with the power switch making sure that
the standby switch is in the standby position first. After a minute or so turn on the standby switch to the Run position. Plug in your
guitar using a good quality screened lead. Press the FET channel select button. Play your bass guitar and adjust the FET Gain
control until your playing lights the amber led in the bar graph display and only very occasionally on loud peaks the Red. If you
find that the gain control has to be set quite low to achieve this, try pressing in the pad switch to lower the input sensitivity. Now
advance the Volume control to the desired listening level. Apply tone correction as desired but try to use small amounts of boost
and cut to your sound. Over correction will nearly always sound bad. Don't forget most of the controls have cut and boost don't
boost them all, cut sounds good too especially in the mid range. Try to always use the minimum tone correction to get your
desired sound. As you adjust your tone you may need to readjust the gain control to maintain the correct level on the bar graph
display.
Ventilation:
Ensure the amplifier is well ventilated and that the top and bottom vents are not obstructed in any way.
Avoid dropping anything in through the vents especially liquids of any kind. If this should happen turn off the product and disconnect
from the power supply immediately and leave to dry out for at least 24hrs.
Rack Mounting:
The chassis may be removed from its wooden cabinet and fitted into a standard 19” rack unit. However the chassis must be mounted
on a metal supporting shelf to provide sufficient support and to cover the exposed areas on the underside of the chassis. Ventilation
must also be considered and adequate provisions made. We do however recommend retaining the amplifier in its wooden case and
transporting in a suitable foam lined flight case when ever possible.
Speaker Cabinets:
The Laney Nexus range of cabinets has been specially designed for use with this amplifier. Their power ratings and impedances
have been carefully matched for optimum performance. Use of other cabinets may result in an inferior sound. (See connection
diagrams for wiring up).
