Installation Instructions
Recommendations for ideal positioning...
PIEGA P SUB 4
The P SUB 4 can be installed flexibly and easily. Due to its relatively small size, it can be integrated in any unit and can be positioned
as required virtually anywhere in the room. However, to ensure the most natural sound, the P SUB 4 should be placed on the floor
near the two front loudspeakers.
Ideal setup:
>For both surround and stereo mode, position the P SUB 4
as close to the two front loudspeakers as possible
>The bass chassis of the P SUB 4 should face the front,
with the connection terminal facing the wall
Surround mode
>Only a small clearance from the wall is required (approx. 30 cm)
for this configuration as the sound is directed forward from the
chassis
>Do not in any way prevent the free movement of the P SUB 4
>Do not place any objects such as vases etc. on the P SUB 4
so as avoid the possibility of accidents
Stereo mode
Note:
Frequencies below 100 Hz cannot be localized by the human ear.
>The exact positioning of the P SUB 4 is largely unnecessary...!

Connecting the System
Configuration example for surround mode
PIEGA P SUB 4
This connection configuration for 5.1 surround applications uses an AV receiver with a separate subwoofer output. Since the AV
receiver handles the bass management in this configuration, the settings for each loudspeaker can be adjusted individually via the
menu. Note that in this case, the LOW PASS setting of the P SUB 4 has no effect (see page 13). Refer to the user manual of your AV
receiver for information on the individual setup controls.

Connecting the System
Configuration example for stereo mode
PIEGA P SUB 4
The power amplifiers of some manufacturers feature separate MAIN IN and PRE OUT terminals, allowing the preamplified signal to
reach the subwoofer and to be looped back again filtered. In this way the loudspeakers are relieved in the deep range, thus gaining
in precision and sound characteristics (see page 13). Refer to the appropriate manual for information about operation and connection
options for your power amplifier.
