Introduction Welcome to the Meridian SW1600 and SW5500 subwoofers. This User Guide provides full information about using the subwoofers in conjunction with your other equipment, to achieve the superb results you can expect from them.
Subwoofer drivers The subwoofers are based on 300mm (12") high-effi ciency long-throw custom drive bass units. The SW1600 uses a single driver, and the SW5500 uses two drivers in a single enclosure. In each case the enclosure is sealed for maximum fl exibility of positioning.
Meridian Surround Processor, such as the G68 Digital Surround Controller, to create a digital surround system with superb music and cinema sound. A SW1600 is ideal as a mono subwoofer for the system, to give exciting cinema effects and added realism in DVD movies.

Setting up the subwoofer This chapter explains how to install your subwoofer. It describes what you should fi nd when you unpack the subwoofer, how you should connect it to your other audio equipment, and the siting constraints.
SETTING UP THE SUBWOOFER Unpacking Before you begin installation you should ensure that your subwoofer is the correct voltage for your local AC supply. If it is not, do not try to install it, and contact your dealer. You should not make any connections to the subwoofer, or to any other component in your system, while the AC power supply is connected and switched on.
SETTING UP THE SUBWOOFER Installing the subwoofer The subwoofer can be mounted using one of four different methods: foot mouldings alone, foot mouldings and spikes, spikes alone, and castors. The mountings are designed to give the subwoofer a stable base on a wide range of surfaces.
Page 17
SETTING UP THE SUBWOOFER To install the spikes on their own, spin the M8 locking nut provided on to the spike and place the washer provided on top of it. If you are using the spikes on their own it is important to use the washer between the underside of the cabinet and the nut to spread the load on the cabinet.

SETTING UP THE SUBWOOFER the hexagonal cutout in the underside of the moulding. Screw the bolt into the base of the loudspeaker using the moulding as a wrench, until the foot moulding is fl ush and fi rm against the cabinet and is not loose. To tighten the drive units The subwoofers typically take about two weeks of normal use for the drive units to settle.
SETTING UP THE SUBWOOFER Positioning the subwoofer Although it is diffi cult to localise very low frequency sounds, to get the best from your system it is important to position your subwoofer carefully. You will probably want to place the subwoofer where it is not to obtrusive, but if possible follow these guidelines.

SETTING UP THE SUBWOOFER The digital connections should be made with high-quality 75Ω screened cable. Suitable cables are available from Meridian. We do not recommend using analogue audio cables, which do not have adequate shielding or the correct impedance, or cables intended for UHF applications, as these do not provide adequate shielding in the 1–30MHz region.
SETTING UP THE SUBWOOFER Connecting the subwoofer to other equipment To connect a subwoofer in a Meridian digital surround system If your system includes more than two Meridian DSP loudspeakers you will need a 511 S-patch box (available separately) to link together the S5 leads from each speaker, as shown above.
Page 23
SETTING UP THE SUBWOOFER • Connect each pair of DSP loudspeakers to the appropriate digital output on the Meridian Surround Processor, using an S5 lead. The other part of the S5 lead is used to distribute the COMMS from the 511 to each pair of DSP loudspeakers.

SETTING UP THE SUBWOOFER To connect a subwoofer to an analogue preamplifi er • Connect the analogue outputs from the preamplifi er or analogue surround processor to the LEFT and RIGHT phono inputs of the subwoofer. The subwoofer mixes the channels to create a mono signal. If your preamplifi...
SETTING UP THE SUBWOOFER Adjusting the subwoofer To set the adjustable low-pass fi lter The subwoofer includes a low-pass fi lter which can be adjusted between 40Hz and 150Hz, or disabled using the DEFEAT switch. If you are connecting the subwoofer to a digital surround processor that provides its own crossover, such as a Meridian digital surround processor, set the low-pass fi...
Page 26
SETTING UP THE SUBWOOFER To set the phase The PHASE switch allows you to invert the phase of the signal to the subwoofer. If your digital surround processor includes a Calibration option you can adjust the phase in the surround processor, in which case set the switch to the + position.
If you are still not able to resolve a diffi culty with the help of this guide and the suggestions in the following pages, please contact your Meridian dealer or Meridian Audio Ltd.
TROUBLESHOOTING Troubleshooting Unit goes silent when played hard The subwoofer has a temperature sensing system on board, which prevents overheating of the electronics.
