UNPACKING INSTRUCTION

CAUTION! Carefully unpack the box upon receipt. Check the contents to ensure that all parts are present and have been

received in good condition. Notify the shipper immediately and retain packaging material if any parts appear damaged from

shipping or the package itself shows signs of mishandling. Save the package and all packaging materials. If the product must be

returned, it is important that the product is returned in the original factory box and packaging.

If the device has been exposed to drastic temperature fluctuation (e.g. after transportation), do not switch it on immediately. The

arising condensation water might damage your device. Leave the device switched off until it has reached room temperature.

CONNECTIONS

1. FILTER SWITCH: In passive mode, a single ampliﬁer can

be used to power all drivers inside the loudspeaker. The

full frequency range is put into the loudspeaker and the

loudspeakers' internal crossover separates the

frequencies, delivering the right frequencies to the right

driver. In the example of a 2-way passive loudspeaker, this

means that the single ampliﬁer is powering both the HF

compression driver and the LF transducer. The internal

crossover takes care of both the frequency and power

separation.

In bi-amp mode, two power ampliﬁers can be used.

This gives you the advantage of being able to

select the best power ampliﬁer speciﬁcations for

each driver inside the loudspeaker. In a bi-amp

conﬁguration, an external crossover is used to

separate the frequencies and this splits the signal

to the dedicated LF ampliﬁer and the HF ampliﬁer.

This way, each ampliﬁer is only working on the

given frequency range and, in turn, is powering the

corresponding driver inside the loudspeaker.

2. INPUT: Receive the signal coming from an external

amplifier.

(PASSIVE +1/-1 connected; +2 -2 not connected)

(BI-AMP +1/-1 LF, +2-2 HF)

3. OUTPUT: Direct link for connecting a second speaker in

parallel.
