outputs of a stereo integrated or power amplifier. The upper frequency limit for this input is variable and is
set by the subwoofer's crossover knob.
2. Line Input: by using an RCA terminated cable, allows the connection of the subwoofer to the line output of
an AV player (DVD, Blu-ray, ecc.) or amplifier. The upper frequency limit for this input is variable and is set
by the subwoofer's crossover knob.
3. LFE Input: by using an RCA terminated cable, allows the connection of the subwoofer to the LFE (Low
frequency Effects) output of an AV player (DVD, Blu-ray, etc) or a home theatre controller/ preamplifier. The
upper frequency limit for this input is fixed at 120 Hz.
4. .1/LFE Level: adjusts the volume when the LFE (RCA plug) input is used.
5. Hi/Low Level: adjusts the volume when the Line (RCA plug) or Speaker Level (Speakon
are used.
6. Crossover knob: adjusts the bandwidth of the subwoofer by setting the low-pass cut off frequency.
7. Auto switch: when this switch is in the AUTO position, the subwoofer automatically switch on or off
depending on the presence of the input signal(s).
8. Phase switch: set the output signal polarity. This helps in choosing the most appropriate low frequency
distribution across the listening room.
9. Mains plug, switch and fuse holder.
10. ON/Stand-by LED
Gravis III
1. RCA unbalanced line inputs: required to connect the subwoofer to the L + R or LFE mono output of the pre-
amplifier/AV receiver.
2. XLR balanced line input: required to connect the subwoofer to pre-amplifiers/AV receivers fitted with
balanced outputs.
