2: Introduction
The MF15 is a 2-way passive speaker designed as a high-quality, compact surround speaker. It would typically
complement speakers from our M series to make a superb surround monitoring system for Dolby Atmos and
other immersive formats.
It is typically used with one of our four-channel amplifiers, such as the DA20 or DA40-ND.
The speaker is available in both vertical and horizontal versions, allowing you to choose the one that suits your
particular installation.
The MF15 has a limited bass response by design. This is fine for small rooms, but when used in larger rooms,
bass management should be used, which is recommended by Dolby Laboratories anyway.
2: Introduction 5
3: Installation
6 MF15 Owner’s Manual
3.1: Electrical Installation
In view of the “custom” nature of every installation for a speaker of this type, no cabling is supplied. The following
are required for the electrical installation of the MF15 system.
Speaker Cables
The connections between the speaker and amplifier should be kept as short as possible. The cable itself should
be high-quality speaker cable, eg 2.5 mm², 4mm² or 6mm² oxygen-free multi-strand copper. The speaker
terminations are on Gold screw down terminals.
The outputs of the amplifiers are on speakON connectors.
Signal Wiring
The amplifier inputs are balanced XLR connections. Always ensure that only high-quality XLR cables are used for
connection to the amplifiers. Typical system wiring configurations are shown in Figures 2 and 3.

Figure 2: Typical 8-channel surround schematic as might be seen in a Dolby Atmos HE 7.1.4 system
3: Installation 7
3.2: Positioning
The MF15 loudspeaker is intended to be part of a surround speaker system, such as Dolby Atmos or a similar
system.
The surround format guidelines in use will therefore determine the position of each MF15 in the room.
The optimum distance from the speaker to the listener is between 1 and 5 meters.
The acoustic centre of the MF15 is midway between the bass and HF drivers. This point should ideally be angled
towards the mixing position both horizontally and vertically to ensure the ecient acoustical summing of all the
drivers. There is, however, some tolerance on this if space for angling the speaker is limited.
If the studio is seeking approval and licensing from Dolby, THX or a similar entity, then these parties or qualified
acoustic consultants should be consulted prior to installation, so that their specific requirements can be met.
8 MF15 Owner’s Manual
3.3: Mounting
The back of the MF15 features four M8 fixing points arranged in a 75 mm × 75 mm square. These can be used
to attach a variety of brackets to the speaker (see drawing below).
WARNING
Fixing screws should not extend more than 30 mm into the cabinet.
WARNING
If these fixing points are not used, then fit screws into them to prevent air leakage.
Option 1: Bracket mounting
The hole spacing matches a Plate type 90 made by Powerdrive. They oer a wide range of wall and ceiling
brackets and pole clamps with the plate 90 attached for simple mounting of the speaker.

Option 2: Flat mounting
If you want to mount the speaker flat to a wall or ceiling, use the DA MF15FIX mounting kit.
This comprises a flat plate that is larger than the MF15 (in the short dimension), which is fixed to the back of the
MF15 using four M8 fixings. This then provides a flange on each side of the speaker to secure it to a wall or
ceiling.

4: Setting up and
adjusting
4: Setting up and adjusting 11
4.1: First time power up
Check that the system has been wired and set up according to the previous instructions, then simply switch on
the amplifier. Check for any hum or buzz, then play some music into the system at a low level. Verify that routing
and phasing are correct, then increase the level to a moderate level.
12 MF15 Owner’s Manual
4.2: Running in
Running in is essential before any judgments are passed or the system is subjected to the maximum level. Failure
to observe this can permanently damage the drivers, resulting in degraded performance for the system’s lifetime.
The easiest way to run a system in is to set the level controls roughly by ear as above, then connect a continuous
music source (eg, a CD player in repeat mode) and leave it to run for at least 12 hours at medium volume levels.
This will achieve a minimum of running in. The system will be run in fully after 5 to 6 days of continuous use. Note
that if the system is left unused for a period of time (days), it may take a few minutes to return to normal
performance after being switched on.
4: Setting up and adjusting 13
4.3: Testing and alignment
There is essentially nothing to adjust in this speaker. As part of a surround system, we would expect a front-end
processor to be in place (eg, Avid MTRX), which will cover filtering, room equalisation, gain control, and time
alignment.
Setup and alignment of the surround system should be carried out by a suitably qualified engineer with knowledge
of room acoustics and speaker system commissioning.
14 MF15 Owner’s Manual
5: Protection
The cones of the LF drivers will be seen to move during normal playback. However, if this gets to a point where
the curved rubber surround is straightening out, then driver damage is likely.
The passive crossover features a self-resetting fuse on the HF unit, providing some protection against long-term
overloading. It is a slow-reacting device, however, so it will not protect against high-level transients, pops, and
thumps.
If the HF unit stops working, turn the level down to its lowest setting, then wait for a while. If the fuse has operated,
it should come back on.
If audible distortion is heard, this is a good sign that the speaker and/or amplifier is being overdriven. Turn it down.
5: Protection 15
6: Care and
Maintenance
High-quality components are used in the MF15, which should provide a long, trouble-free life. Here are a few hints
to help them on their way.
▪ Never touch the drive units, especially the tweeter, which is very easily damaged. If the speakers are being
moved or work is going on nearby, replace the plastic tweeter protection domes that came with the
system.
▪ Avoid running the system into clipping or distortion. The amplifiers have clipping indicators on their front
panels. When an amplifier clips, it can send potentially damaging DC components to the drive units. They
may not fail immediately, but prolonged exposure to clipping will ultimately lead to failure. Set limiters to
prevent this from occurring.
▪ Avoid unplugging or switching o any equipment that is connected to the monitor system without first
muting the crossovers or switching o the amplifiers. Large spikes are often generated when equipment is
switched o, which will be amplified to a potentially damaging level.
▪ The amplifier power provided with the MF15 is specified at a level to oer the best possible reproduction of
dynamics and short-term transients, and as such is capable of damaging the system if run continuously at
high levels.
▪ The very low distortion of these monitors means that it is easy to reach high SPLs without realising it. This
can be potentially damaging to both the monitors and the user’s ears. Take care of your monitoring levels.
