AMPLIFIER OPERATION GUIDANCE

Connection and setup

With the DMA-6120MX power switched off (20), connect the rear IEC inlet (34) to the mains using the supplied mains lead (or an equivalent approved type). Ensure that the voltage is correct and the speaker connect is correct then power on

The DMA-6120MX has 5 input channels and an integral multi-source audio player. Microphone input 1, 2 and 3 are designed for either microphones or line level sources (such as a CD/mp3 player or output from a mixer) via combo connectors on the rear panel, it is switch able by DIP switch. These can accept either XLR or 6.3mm plugs for balanced or unbalanced signals.

DIP switches

Mic/Line inputs 1, 2 and 3 each have 2 DIP switches on the rear panel to set the input level and/or activate +20V phantom power for use with condenser microphones.

Set the level correctly for the type of input source connected (Mic or Line) If the source connected is a condenser microphone which requires phantom power, make sure that the phantom is switched on for that channel.

Be sure to make these DIP switch settings when the amplifier is switched off. Making any changes when the amplifier is powered up may cause loud bangs through the system which can damage the speakers.

Signal Inputs and Outputs

Connect microphones or line signals to Mic/Line 1, 2 and 3 inputs (27,28,30) using good quality signal leads. A stereo or mono line level source can be connected to the Auxiliary channel 4 input on 2 RCA connectors (26)

For checking the output of any zone, an assignable Monitor output can be connected to headphones from the front panel 6.3mm jack (15) or as a line output (e.g. to active speakers) from RCA connectors at the rear (24)

Each zone output has a dedicated RCA signal output on the rear panel (23), which can be connected to the line inputs of active speakers or amplifiers. These are in addition to the speaker outputs detailed below.

An antenna input (32) is provided on the rear panel for connection to an external aerial for FM tuning There are Bass and Treble volume control on rear panel to adjust the sound of MIC and Line input signal

Speaker outputs

The DMA-6120MX has a separate speaker output for each zone, connected via 3 large modular terminal plugs. Each plug can be removed from the rear panel for convenient connection of speaker outputs to 2 zones.

Each zone output can be used to power either 100V line speakers or standard low impedance speakers. These 2 configurations cannot be used together, so it is important to decide which will be used at the start.

100V line systems

For 100V speakers, connect the selected zone output to the first speaker in the zone using double insulated speaker wire which has adequate current rating to handle the total output of the amplifier.

Connect the “100V” output terminal for the selected zone to the positive (+) connection of the speaker and “COM” output to the negative (-) connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals and connected together and all negative terminals connected together as shown below.
Speaker outputs

A 100V line speaker system can comprise of many speakers connected together. The determining factor for how many speakers can be used on a single amplifier is the power rating. For most purposes, it is advised to connect as many speakers as needed with a combined wattage of no more than 80% of the amplifier’s output power rating (in the case of the DMA 6120MX, this is 120W per zone output)

The terminals of a 100V speaker are connected via a transformer and if necessary, this transformer may be “tapped” for different power ratings. These tappings can be used to adjust the wattage (and output volume) of each speaker in a zone to help achieve the ideal total power of the system for the relevant zone outpu

Low impedance systems

Alternatively, each zone output of the RM 306 is capable of powering one or more low impedance speakers. There is an option on each zone for either a 4Ω or 8Ω speaker output to determine the minimum impedance. It is essential to select the correct output terminal when opting for low impedance speakers.

For a single 8Ω speaker, connect the positive (+) wire to the “8Ω” terminal and the negative (-) wire to “COM” For a single 4Ω speaker or for 2 x 8Ω speakers connected in parallel, connect the positive (+) wire to the “4Ω” terminal and the negative (-) wire to “COM”

In either case, the connected load should have a combined impedance no lower than stated on the terminal. Lower impedance may cause irreparable damage to the amplifier.
The connected speaker(s) must also have a power handling to accept up to 30Wrms from the zone output. Lower power handling may risk damage to the speakers

Operation

When all connections to the amplifier are made, turn all rotary controls down and switch on the power and the power LED will illuminate.

To check for correct operation of the system, select an input source and output zone for testing. In the following example, Mic/Line 1 input and Zone 1 output have been selected.

Press Z1 button on the line of MIC/Line1, if zone1 display C2, that means MIC/Line1 output to zone 1 If you playing MP3, press zone1 on the line of MP3, then zone 1 will have MP3 music and display on Zone1 will show C1

If Zone 1 cannot be heard from the location of the DMA-6120MX, use the monitoring feature as follows Press the button of Monitor (12) and connect headphones to the Monitor output (15) Make sure that the Monitor button for Mic/Line 1 is pressed in and listen through the headphones Gradually turn up the Monitor level control and check for the output to Zone 1

Onboard Multi-Source Audio Player

The 6120 is fitted with a built-in audio player, operated via a backlit LCD display and transport buttons. This section provides access to a Bluetooth™ receiver, FM radio tuner and USB/SD audio player
In order to play audio to one of the zones, it is necessary to press in one of the “Play” buttons (4).
Onboard Multi-Source

Mode: Select between Bluetooth, FM tuning, USB or SD playback

Play: play music
Folder: hold on the music
Prev: Back to last music
Vol+: Increase volume
RPT: repeat the music
Next: go to next Music
Vol-: Reduce Volume

Bluetooth Operation

In order to play back audio from a smartphone, tablet or other Bluetooth device, the built-in Bluetooth receiver will need to be paired with a device which is within range.”

To pair a device with the DMA-6120MX Bluetooth receiver, it is necessary to scan for devices in the Bluetooth menu of the sending device and select to pair with “BT66078”. Once paired, the DMA-6120MX display will show it is connect
Bluetooth Operation

Select to connect as an audio device and play audio tracks on the smartphone or tablet (or other) and the audio should be heard on the selected zone.

The buttons labelled “Prev” and “Next” can adjust the audio player output volume. Press and hold “Prev” to increase volume or press and hold “Next” to decrease volume.

If the sending device goes out of range or the Mode of the audio player is changed, the connection will stop. Returning to within range or to Bluetooth mode will restore the pairing.
It may be necessary to re-select connection as an audio device on the sending device.

FM Tuner
Press the Mode button to switch to the FM tuner function. For good FM reception, it will be necessary to connect an external aerial to the Antenna connector on the rear panel using good quality coaxial RF cable terminated .

If no channels are tuned in, press the Play button to begin auto tuning, which scans available stations and stores them as channels within the DMA-6120MX FM tuner. To step through pre-set stations, press the Previous or Next buttons.

USB/SD Player

The 6120 audio player has inputs for a USB pen drive or SD card with standard compressed digital audio files on them. Inserting either or both of these will switch the player to read from these sources and the display will show “MP3 Mode”.

After you Insert the USB it will play automatically, you can use “Prev” or “NEXT” to choose last or next song, “REPT” is for one song or all song repeat.
