EFFECT LOOP OPERATION
On the rear panel of the Singleman H you will find SEND and RETURN jack sockets with an adjacent LOOP
ON switch to activate the loop. The effects loop switch can only be operated manually.
SEND is the output signal to the effect input (pedal or rack mounted effects units). RETURN is the input
connection for the signal processed by the effects unit to be passed to the final section of the amp. For all
LOOP connectivity you should use only very short, high quality, shielded cables. Any effects system will modify
the original timbre of the amplifier to some degree, depending on the quality of the system you employ.
Connect only modulation or ambient effects to the loop, such as chorus, flange, delay or reverb to obtain
the best sound performance. Effects pedals/units are normally equipped with a ‘Level’ or ‘Mix’ control to
achieve the desired effect level.
PowerLimit® power reduction system is another great feature of this unit. It operates
by changing the internal configuration of the tubes, decreasing the output power to 1/4
or 1/25 of the maximum power. This system does not dissipate excess power through
dummy loads, but instead forces the tubes to give the best at low power levels. In essence
it is a ‘shaping’ method, designed by Marco Brunetti, to reduce the amp’s maximum sound
pressure whilst preserving the timbre.
This system enables you to play in different environments by simply adjusting the output
volume of the amp without the need to re-set the EQ. Many different sound nuances can also
be achieved at the power stage, including overdrive.
