E-PAC, the E-Series Power Amplifier Controller, is a single channel amplifier with an internal controller for operating E-Series systems.
Unlike the modular design of the controller modules for P1200A and A1 mainframes, the internal controller is based on Digital
Signal Processing, DSP. The E-PAC is pre-programmed for E-Series and C6 loudspeakers and their different operational modes, the
configurations are selected by setting DIP-switches on the rear panel. The E-PAC has an additional linear configuration for MAX
loudspeakers.

The E-PAC is specifically designed for high impedance loads (200W into 16 ohms, 300 W into 8 ohms), and therefore provides the
same output power for a single 16 ohm E3 loudspeaker as one channel of a P1200A mainframe. The nominal 8 ohm impedance’s
of other E-Series loudspeakers result in a single cabinet having a maximum SPL of 2 dB less than when driven by a P1200A.
Up to four E3 loudspeakers or two 8 ohms loudspeakers can be driven with a reduced output level (–6 dB). This is useful for
situations where multiple loudspeakers are needed but maximum output is not required.
All the functions of the E-PAC, including programmable internal delay settings, can be remotely interrogated and altered via the
RIB, Remote Interface Bridge and a PC.

The controller incorporated in the E-PAC is based on a Digital Signal Processor, DSP, utilising sigma-delta signal conversion and is
pre-programmed for

- E3, E9, C6, E12-SUB, E18-SUB, C16/C19 and MAX (linear mode).
- E3, E3 CUT, E3 HFE, E3 CUT HFE, SUB and MAX (linear mode).


These configurations can be selected by setting DIPswitches on the rear panel.
The signal processing includes correction of the frequency response, a high pass filter, limiting and complex protection circuits
that model loudspeaker cone displacement and voice coil temperature. The DIP switch settings are specific to the characteristics of
individual loudspeakers, affecting the frequency response and maximum output level. To ensure optimum performance and
prevent damage to system components each type of loudspeaker has to be used in conjunction with a suitably configured E-PAC.
Delay settings up to 170 ms can be programmed into the controller using a RIB, Remote Interface Bridge, in conjunction with
a PC running d&b ROPE control software
