100 Volt and 70 Volt direct drive modes
The use of either the 70 V or 100 V modes allow connection of high impedance (HZ)
loudspeaker lines without using output transformers (direct drive). In this case the
maximum number of loudspeakers connected to an output channel is only limited by the
amplifier channel output power.
It is recommended that this mode should be used if the distance between amplifier and
speaker is larger than 50 m of cable distance (approx. 150 ft) and/or a high number of
speakers with transformers are used.
When 100 V or 70 V is selected a 50 Hz High Pass filter is automatically activated to reduce
the possibility of loudspeaker transformer saturation to ensure the best performance.
8 Ω mode
In 8 Ω mode the power amplifier reaches rated output power having a load of 8 Ω
connected.
4 Ω mode
In 4 Ω mode the power amplifier reaches the rated output having a load of 4 Ω connected
(e.g. one 4 Ω speaker or two 8 Ω speakers in parallel). These configurations can be driven
by each amplifier channel. This mode usually used if multiple speakers with medium or
low‑power rating are driven in low impedance mode (LZ).
