7. NOTES ABOUT LOW IMPEDANCE CONNECTIONS
WARNING! CAUTION!
- The total loudspeaker impedance must not be lower than the amplifier output impedance. Note: a loudspeaker total
impedance equal to the amplifier output one permits to get the maximum deliverable power (but an higher loudspeaker
impedance entails less power).
- The total loudspeaker power shall be adequate for the maximum deliverable power of the amplifier.
- The loudspeaker line shall be short (for long distances, it may be necessary to use cables with large cross-section wires).
- Always use cables having wires with an adequate cross-section, considering the cable length and the total loudspeaker
power.
- Loudspeaker lines must be kept separated from the mains cables, microphone cables or others, in order to avoid inductive
phenomena may cause hum or noises.
- Use loudspeaker cables with twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic
fields.
- Do NOT connect the low impedance input directly to 70 / 100 V constant voltage lines.
