23. OUTPUT
:
(23)
Provide for connection of external 16ohm speaker cabinet.
NOTE: The way connect with speaker
(1)
Connect three speakers at same time, The impedance of each speaker must 12ohms
(2)
Connect with two speakers in the meantime, If you use INPUT 21 and 22 (4ohms and 8 ohms), The impedance of each speakers
is 4 ohms. If you use INPUT 22 and 23 (8 ohms and 16ohms),The impedance of each speakers is 8ohms
(3)
If you only connect one speaker, please connect according to the impedance.
24. DI
:
(24)
XRL DI out for recording.
T
he RED BOX has for years set the industry standard for analog guitar DI boxes with built-in speaker
emulation. It converts the PGA 18H’s speaker out signal, which is tapped post power amp and pre POWER SOAK, into a balanced,
frequency-compensated signal that you can patch directly to a mixing or recording gears. This signal it sounds very authentic, much
like that of a guitar amp, when rendered by a PA or studio monitors. The channels’ MASTER settings directly affect the signal level,
but the selected POWER SOAK mode does not.
