INPUT
Balanced XLR-F + JACK connectors (0 dB / 30 kOhms): SPX SUB has two input connectors connected
in parallel, to enable the signal to be sent on to a second unit (e.g. another enclosure). The internal power
amplifier input can receive balanced or unbalanced high impedance line signals from high level output
units. SPX SUB has two independent LEFT & RIGHT inputs (XLR-F+JACK): this enables the sub-woofer
to be used in STEREO (1 sub + 2 satellites) or MONO (2 subs + 4 satellites).
VOLUME
Control of the signal level sent to the built-in amplifier: operates with continuous values ranging from
fully closed (“
∞
” position: the signal is not sent to the amplifier) to fully open (“0dB” position: the signal is
sent to the amplifier at the same level at which it arrives on the input). In other words, this control is used
to cut the external signal sent to the amplifier. In the SPX SUB the volume control regulates the signal
sent to the built-in amplifier: therefore, using this control only the sub-woofer volume and NOT the satellite
volume will be modified.
