Footswitch Sockets
These sockets are connected to latching footswitches. The first one is dual function and
operates the extra gain stage (with VOLUME pulled out) and reverb. The second turns the
effects loop on or off if used.
Effects Loop
This has sockets for SEND, LEFT/MONO RETURN and RIGHT RETURN as well as a switch for
SERIES or PARALLEL configuration.
The SEND is for connection to the input of effects units and can drive floor type battery
powered effects pedals or 19" rack type studio effects units.
The RETURN sockets are for connection to the outputs of effects units. If a mono effect unit is
used then use the LEFT/MONO RETURN.
The SERIES/PARALLEL switch alters the configuration of the effects loop.
In SERIES mode the whole signal comes out of the amp, into the effects unit and then back
into the amp, whereas in PARALLEL mode the effected signal is mixed in with the original dry
signal, thus retaining tonal purity of the dry signal.
The choice of which mode to use will depend on what kind of effects unit is used and what
overall effect is desired. Generally if time delay effects are used, such as delay (echo), chorus,
flanging, phasing, etc., then the PARALLEL setting is usually preferred. If volume or EQ related
effects are used, such as overdrive/distortion, compression, graphic equalisation, wah-wah or
volume pedals, or if a multi-effects unit is used with a combination of time delay and volume
related effects, then it is usually best to set the switch to SERIES. There are no rules, it is best
to experiment and see what you prefer. If PARALLEL configuration is used then, if possible, it
is recommended that dry/direct signal from the effects unit is turned off.
The effects loop is not activated unless a jack plug is inserted into the LEFT/MONO RETURN
socket. The loop is then footswitchable if a suitable latching footswich is connected to the
appropriate footswitch socket.
It is also possible to use the Velocette Twin purely as a stand alone mono/stereo power amp.
To do this set the loop to SERIES configuration, this will effectively eliminate the preamp and
plug signal source(s) into the RETURN socket(s).
External Speaker Outputs
These have been provided throughout the Velocette range so that the user can connect them to
external 16Ω speaker cabinets, such as 4 x 12's, for different sounds. This is useful for both
live and studio use and will radically change the sound and volume of the amplifier.
As the Velocette Twin has two power stages, two external speaker outputs are provided, as is a
8Ω or 16Ω impedance selector switch which sets the output impedance for both sockets.
(N.B. This does not change the impedance of the internal speaker connection)
