REAR PANEL

13) SPEAKER OUTS

 One 4 ohm, one 8 ohm and one 16 ohm jack are provided for connecting the head to a speaker cabinet.

Verify the impedance of your speaker so you know which jack to use. If you want to use the amp with two 8 ohm cabs (a 4 ohm load) connect 
one cabinet to the 4 ohm jack, and connect the two cabinets together with another speaker cable. For two 16 ohm cabinets, connect to the 8 
ohm jack and connect the two cabinets together. 

14) PRE OUT – AMP IN

 The Little 40 features a series preamp output and power amp input which can be used for connecting with outboard 

effect processors or pedals. This loop is wired between the preamp and the power amp, and its level is optimized to match well with most 
quality effect processing devices. Simply connect the Pre Out jack to your processor’s input, and connect the output of your processor to the 
Amp In jack. You can also use the Pre Out to send to another power amp, recording device, DI, etc.

15) FSW

 Connect a single (mono) footswitch here (available separately) for a 10 dB boost (10).

16) TUBE MODE

 This switch allows you to switch between the two tube operating modes, Pentode and Triode. Each mode has different 

power outputs: 
Pentode: 1 ÷ 40W (from 1W class A to 40W class AB)     
Triode: 0,5 ÷ 15W (from 0,5W class A to 15W class AB)  

17) BIAS Switch (low/high)

 The Little 40 can operate in either Low Bias mode or High Bias mode. When this button is pressed in, the 

power tubes work in High Bias mode; when the button is depressed, they work in Low Bias mode. In Low Bias mode, the tubes use less power 
and less ‘tube life’ is taken out of them. High Bias mode gives top quality and power, and higher-fidelity sound—but the power consumption 
and dissipation of the tubes increases. In either mode, unlike other tube amplifiers, the Little 40 is able to greatly prolong the life of its tubes 
by keeping them optimally biased at all times. 

18) SERVICE

 The optional ATCS (Advanced Tube Control System) interface allows users or service technicians to connect this port to a 

computer—and with dedicated software—collect technical data and tube parameters from the amp.
