RCF HL 2290 Руководство по эксплуатации онлайн [13/28] 757998

ENGLISH

THREE-WAY MODE (WITH HS 2200 SUBWOOFERS)

At least three ampliers (one for each way) and an external crossover are necessary.

HL 2240, HL 2260, HL 2290

low-frequency nominal impedance: 8 Ω

low-frequency recommended amplier power: 2700 W

high-frequency nominal impedance: 8 Ω

high-frequency recommended amplier power: 300 W

HS 2200 SUBWOOFER

nominal impedance: 8 Ω

recommended amplier power: 1800 W

Suggested crossover frequencies:

- 80 ÷ 120 Hz (HS 2200 subwoofer cutoff)

- 600 Hz (HL 2240, HL 2260, HL 2290 woofer / tweeter).

GENERIC NOTES ABOUT LOW IMPEDANCE CONNECTIONS

- The total loudspeaker impedance must not be lower than the amplier output

impedance. Note: a loudspeaker total impedance equal to the amplier output one

permits to get the maximum deliverable power (but a higher loudspeaker impedance

entails less power).

- The total loudspeaker power shall be adequate for the maximum deliverable power of

the amplier.

- The loudspeaker line shall as short as possible (for long distances, it may be necessary

to use cables with large cross-section wires).

- More loudspeakers linked in parallel: if the single loudspeaker impedance is 8 Ω, the

total impedance is given by 8 divided by the loudspeaker number. For example: the total

impedance of two loudspeakers linked in parallel is 4 Ω.
