Fan: The cooling fan is automatically controlled by how hard the amplifier is having to work. So during quiet playing the fan will be

almost silent and during loud passages the speed will increase to assist cooling.The amplifier is designed with plenty of ventilation so

overheating is very unlikely unless the ventilation is obstructed. Should this happen the amplifier will automatically turn to standby mode

and not switch back on until it has cooled. During this period the fan will revert to high speed mode to speed cooling. Whilst waiting,

check that the fan and the ventilation are not blocked. This will speed the return to normal operating.

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.

Speaker Connectors: There are two parallel connected Speakon /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 Speakon 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.

When using Jack leads ensure they are properly rated speaker cable and not instrument types. Jacks should be wired tip to + speaker

terminal and body to - speaker terminal. For long term reliability we recommend using Speakon connectors when ever possible.

Preamp out Power Amp in jacks: These jacks are primarily used to connect other power amplifiers or connect Nexus Tube amplifiers

together to boost power outputs. When connecting to another power amplifier the preamplifier output jack should be used. The level at this

jack is nominally +13dBu or 3.4V at full power. The signal at this socket will be affected by all the controls on the preamplifier. When

connecting two Nexus Tube amplifiers together to boost power levels the master amplifier preamplifier out jack should be connected to the

power amplifier input socket of the slave. The master will then be in complete control of the slave power amplifier.

DI output socket and switches: This socket is a balanced signal output for sending to mixing desks, PA etc. The signal may be sent from

the preamplifier before any of the EQ controls or effects (Pre-Post switch set to Pre) or after the EQ and effects but prior to the Volume

control (Pre-Post switch set to Post). The nominal level is -20dBu or 100mV. A ground lift switch is provided to avoid any hum problems

there may be when connecting to a mixing desk/PA. (Try it set in both positions to find the best performance).

Tuner Out Jack: This socket is normally used for connecting a tuner to allow continuous tuning of your guitar. When the amplifier is muted

a signal is still present at this socket. The output level is similar to your guitar.

Effects Send Return Jacks & Bypass switch: These sockets are used for connecting external effects processors to your amplifier. The

insertion point is after the onboard preamplifiers and EQ but prior to the Volume control. Use the send jack to connect to the input of your

processor and the return for the output. The loop is an insert type so all of your signal is routed via the external processor. So any blending

between direct and processed signals must be performed in the processor. When not using the Loop it is advisable to operate the Effect

bypass switch to avoid any reliability problems sometimes associated with jack connectors, even though gold jack sockets are used here for

increased reliability. The signal level is nominally -10dBu or 250mV.

Footswitch connector: This D type connector is used to connect the included dedicated FS7 footswitch to the amplifier. Never use it for

any other purpose as damage may result.
