This will prevent unnecessary power loss in the mains cables. If circumstances do not allow
this, it is advisable to connect the adapter block directly to the power supply using a short cable
and then connect the individual ES 40's to it using longer leads. Although this method is not
ideal, it does limit power loss as much as possible.
Ultimately, it is possible to place the adapter block near the ES 40s, but if a great deal of power
is required from the units, the final current provided is far from optimum: loss of current leads
to unrecoverable loss of output power and therefore sound pressure.
Warning :
Always disconnect the ES 40 from the mains power supply before operating on the fuse holders!
Replace a blown fuse only with a new one of the same type and value!
Current Table
Below, the current consumption of the ES 40 is tabulated for two selectable mains voltages.
The power consumption shown applies to 1/8 of maximum output power pink noise in 2 Ω, which
is representative for typical music program with occasional clipping. If your speaker system has
an impedance of 4 or 8 Ω, you may multiply the currents by 0.5 or 0.25.

Current consumption as a function of the mains voltage at 1/8 of maximum
output power with pink noise in 2 Ω.
The mains voltage may NOT deviate more than -20 % to +10 % of the nominal value. The
proportional mains voltage cable loss may not exceed 10 %. The following formula may be used
to calculate the maximum mains cable length in meters for 220-240 V models:
