In - Single phono cable can be connected here from a home cinema
receiver's LFE/Subwoofer output.
Out - Single phono cable can be connected here to loop the LFE In signal
onwards to another Subwoofer.

In - Single cable can be connected here from a device that has a Trigger
output. A 5-12V DC trigger input will wake the Subwoofer up from
Standby.
Out - Single cable can be connected here to loop the Trigger In signal to
another device.

7. Connections

Note: Before making any connections, make sure that the subwoofer and
amplifier are switched "OFF".
The Mezzo 9 can be used in two basic configurations:
1. With an amplifier without a dedicated filtered Subwoofer output.
2. With an amplifier (such as a home cinema receiver) which does have a
dedicated filtered Subwoofer output.
In fact if required it is possible to make both connections at the same time
and switch between them (see details later).
Amplifiers without a dedicated Subwoofer output:
For this configuration there are two options, either you can connect the
Mezzo 9 to the amplifiers preamp output or its speaker outputs (the
Mezzo 9 uses whichever you choose automatically). In both cases the
Mezzo 9 then performs the required low-pass filtering and summing to
mono internally to create a subwoofer channel. See below:

High Level Input L/R
5
Speaker cable or other wire can be connected here from an amplifiers high
level loudspeaker terminals. The Mezzo 9 presents a high input impedance
to the amplifier and can be wired in parallel with the main speakers.
The Mezzo 9 will no draw any significant current from the amplifier and so
a large gauge speaker cable is not required.

Once you have completed all the connections to the subwoofer, plug the
AC power cable into an appropriate mains socket then switch on. Your
subwoofer is now ready for use.
Option 2
A high quality stereo phono/RCA cable is the preferred connection type,
use the high-level connection option below only if your amplifier does not
feature pre-amp outputs.
Loudspeaker
In this case, use speaker cable or other wire. The Mezzo 9 presents a high
input impedance to the amplifier and is wired in parallel with the main
speakers. The Mezzo 9 will not draw any significant current from the
amplifier and so a large gauge speaker cable is not required, small gauge
cable can be used, and as the amplifiers output impedance will normally
be very low screened cable is not required.
