Operation with E-PAC
To drive E3 cabinets the E-PAC has to be configured to E3 mode.
For an E-PAC version 1 and 2, the configuration is selected by
setting the appropriate DIP switches on the rear panel.
For an E-PAC version 3, the configuration is set via a front panel
digital rotary encoder in conjunction with an LCD.
The CUT and HFA settings are available on versions 2 and 3. The
characteristics of the CUT and HFA settings are explained on the
previous page under the section "E3 controller module switches".
The E-PAC can drive up to two E3 cabinet at an output power of
300 watts. LO IMP mode allows the E-PAC to drive four E3
cabinets with a 6 dB reduction of input level to the speakers.
