NOTE:
The Matrix’s volume controls are basically
attenuators. That means that to achieve full power at
their specified load they requires a signal of .775v
(0db) and the volume knobs up full. If you put a higher
level signal into the amp, it will achieve it's full power
rating earlier than at full volume position and inversely,
if you put a lower level signal in, say -6db, the amps
full volume will always be -6db of full power rating.
If your volume is lower than expected even with the Matrix amp on full
then look to increse the signal level going into the amp. This could be the
individual patch volume or the master volume of the unit or indeed the
send level of a preamp. Be aware of the noise floor of a unit as well.
Turning something up full will usually turn up the amount of noise the unit
generates. The Matrix units are obviously designed to be turned up full
and have a low level of noise/distortion but you may experience issues if
you turn up the signal being fed into the Matrix too much and have the
volume of the amp set too low.
Important Notice regarding connection to multiple
input and switchable input cabinets.
Care must be taken when connecting the amp to any
cabinet that has more than one jack plug or socket or
features switchable stereo/mono operating modes.
Certain cabinets are known to have more than one
socket but are not stereo capable cabs.
Orange
®
2x12 and 4x12 cabs for instance have two unlabeled parallel
inputs. Connecting the amplifier to both inputs effectively shorts the
amplifiers outputs and will cause damage to the amplifier.
This will not
be covered under warranty.
Similarly, cabinets which feature stereo/mono switchable inputs
(Marshall
®
style) must always be switched to stereo operation when
both channels of the amplifier are connected to it. Switching to mono
mode will turn the input into a parallel output and again effectively link
and short the amps channel outputs together. If you are unsure of your
cabinets’ specifications, please refer to the manufacturer’s instructions
or consult a qualified technician for guidance. Care must also be taken
with Mesa
®
style cabinets to use the applicable socket for stereo or
mono and manually switch to the correct one(s).
If in doubt consult your cabinets manual or relevant support page.
