SSW-351

The SSW-351 contains a built-in crossover network.

There are several ways in which an additional speaker can be connected to the SSW-351.

1. Since the HIGH FREQ OUTPUT is routed through the internal crossover network, a signal from which the low range has been cut will be sent to the connected speaker.

from the amplifier

For superior quality in sound reproduction, we recommend the use of a reverse polarity cable for this connection.

In this case, the combined impedance will be 8 ohms.

3. The speakers can be driven by multiple amps very simply with the internal crossover network. When driving the speakers with two power amps (bi- amping), connect the speakers using the parallel input jacks.

The volume balance between the subwoofers (SSW- 351) and full-range speakers (SST-151/251) and be adjusted with the power amp level settings.

Using two power amps provides greater headroom when driving the speakers.

2. The PARALLEL INPUTS can be used as an output to connect an auxiliary woofer or a full range speaker. A full frequency range signal will be sent to the connected speaker.

In this case, the combined impedance will be 4 ohms.

A method to increase low-range sound pressure levels.

4. If you wish to use an external channel divider (crossover network) instead of using the built-in crossover network, make connections to the DIRECT INPUT. Pay attention to the crossover frequency of each speaker that is connected.

Carefully read the specifications before

connecting an external channel divider

(crossover network).

For the crossover frequency, we recommend frequencies between 100 Hz and 200 Hz.
