Connections
BAL. LINE INPUT The signal to be re-amplified should be connected to the RA-10’s balanced line input. In typical applications this
would be an output from an audio interface or mixer, but could also be the output of a synthesizer or tape recorder. The RA-10’s
balanced line input will happily accept both balanced and unbalanced signals at a wide range of levels. XLR wiring configuration: ‘Pin
2 hot’.
INST. OUTPUT Use a standard TS (tip-sleeve) instrument cable to connect the RA-10’s instrument output to the pedal, amp or device
through which you wish to re-amplify your signal. The RA-10’s instrument output delivers a relatively high impedance, low level signal,
similar to that of a guitar or bass output.
Note: When re-amplifying through devices 5 meters or more from the audio interface or source, it is advisable to keep the RA-10 close
to the amplifier or pedals, and make the longer cable run using the balanced cable feeding the RA10’s input. This will ensure the
lowest possible noise floor.
Controls
LEVEL Use the level control to adjust the amount of signal fed to the pedals or amplifier. A good rule of thumb is to start with the
control at about 7 and adjust to taste.
Z The impedance control adjusts the RA-10’s output impedance from about 600
Ω
to 50k
Ω. In traditional reamping situations this
can be used to “load” your amp and pedal inputs like different styles of guitar pickup would. Think “active pickups” to the
left, and “Telecaster” to the right. There are no rules with the Z control, and the best setting is the one that sounds best to
you. In some cases the impedance control will do little or nothing, in others it will introduce wildly different frequency
responses and distortion characteristics.
GROUND The RA10’s ground switch disconnects the XLR input pin 1 from ground. This can alleviate the low frequency hums or
buzzes caused by “ground loops”. This is likely to occur when the audio interface and amplifier are connected to separate power
outlets, such as when re-amplifying through an amplifier on the studio floor from a source in the control room. When the switch is in
the up position, pin 1 is connected to ground.
