6*6 ZONES MATRIX AMPLIFIER WITH MP3/FM/BT PLAYER

3.5 SPEAKER OUTPUTS

The P X-6120 has an independent output for each zone, connected via 3 large plugs with modular

terminals. Each plug can be removed from the back panel for convenient connection of the speaker out-

puts.

Each zone output can be used to power either 100V line speakers or standard low impedance speakers.

These two configurations cannot be used together, so it is important to decide which one will be used initially.

3.6 100V LINE SYSTEMS

For 100 V speakers, connect the output of the selected area to the first speaker in the zone using a

dual-insulation speaker wire with sufficient rated current to support the full output of the amplifier.

Connect the output terminal «100V» of the selected area to the positive connection (+) of the speaker

and the output «COM» to the negative connection (-) of the speaker. Connect other speakers in parallel

with the first speaker, with all positive terminals connected together and all negative terminals connected

together, as shown below.

A 100V line speaker system can include many speakers connected together. The determining factor in

knowing how many speakers can be used on a single amplifier is the rated power. In most cases, it is

advisable to connect as many speakers as necessary with a combined power not exceeding 80% of the

rated output power of the amplifier (in the case of the PX-6120, this represents 120W per output area).

3.7 LOW IMPEDANCE SYSTEMS

Alternatively, each zone output is capable of powering one or more low-impedance speakers. There is an

option on each zone for a 4Ω or 8Ω speaker output to determine the minimum impedance. It is essential

to select the right output terminal when opting for low-impedance speakers.

For a single 8Ω speaker, connect the positive wire (+) to the terminal «8Ω» and the negative wire (-) to

«COM» For a single 4Ω speaker or for 2 8Ω speakers connected in parallel, connect the positive wire (+)

to the terminal «4Ω» and the negative wire (-) to «COM».

In both cases, the connected load must have a combined impedance not lower than that indicated on the

terminal. Lower impedance can cause irreparable damage to the amplifier.

The connected speaker(s) must also have a power capacity to accept up to 120 Wrms from the exit of the

zone. A lower rated power may damage the speakers.

3.9 OPERATION

Once all connections to the amplifier have been made, lower all rotating controls and turn on the device;

the power LED lights up.

To verify that the system is working properly, select an input source and output area to test. In the following

example, the Mic/Line 1 input and the Zone 1 output were selected.

• Press the Z1 button on the line of MIC/Line1, if zone 1 displays C2, it means that the output MIC/Line1

is routed to zone 1.

• If you want to play your MP3s, press the Z1 button on the MP3 line, zone 1 will receive MP3 music and

the screen in zone 1 will show C1

If zone 1 cannot be heard from the location of the P X-6120, use the monitoring function as follows :

• Press the Monitor button (12) and connect a headset to the Monitor output (15).

• Make sure the Monitor button for Mic/Line 1 is pressed and listen to the headphones Gradually increase

the monitor level control and check the output to zone 1.

3.10 EMBEDDED MULTI-SOURCE AUDIO PLAYER

The P X-6120 is equipped with a built-in audio player, controlled by a backlit LCD screen and carrying

buttons. This section provides access to a Bluetooth™ receiver, an FM radio tuner and a USB/SD audio

player.

In order to stream audio in one of the areas, it is necessary to press one of the «Play» buttons (4).
