MONITOR AUDIO Bronze Series Owner’s Manual

Owners manual

Introduction:

The Bronze Series has been intricately engineered to optimize your audio experience, whether you’re listening to your favorite album or watching the latest Hollywood blockbuster.
Consisting of eight different models, you can create the perfect sound system to suit your music or home cinema needs, from our compact bookshelf speakers to the powerful yet detailed performance of our larger floor-standing speakers. With the addition of our new Dolby Atmos® Enabled upward-firing speakers, you can add a whole new dimension to your favorite movie experiences.
Bronze Series is made for you, for your home, and for the performance you desire.

Attaching Feet and Spikes

For Carpeted Floors
(Bronze 200 and 500 only)

The spikes and ‘outriggers are supplied assembled for use on carpeted floors or where spikes are appropriate. All that is required is to fix them to the speaker base using the supplied bolts (A & B).
You can check that the speaker is level on all sides by using a spirit level (not supplied). If it’s slightly off-level, unscrew the spike and check again. Continue this process until the
cabinet is fully level. Use the locking nuts on each foot to fix the spike in place and to stop any unwanted vibrations.
Please ensure there are no hidden wires under the carpet that could be damaged by the spikes.

For Wooden/ Hard Floors
(Bronze 200 and 500 only)

Remove the spikes and replace them with the supplied rubber feet. Fix the ‘outriggers to the speaker base with the padded side touching the cabinet using the supplied bolts (A & B).
You can check that the speaker is level on all sides by using a spirit level (not supplied). If it’s slightly off-level, unscrew the rubber foot and check again. Continue this process until the cabinet is fully level. Use the locking nuts on each foot to fix them in place and to stop any unwanted vibrations.

Setting Up Your Loudspeakers

2 Channel Positioning

When arranging a 2 channel (stereo) system, the listening position and the loudspeakers should form an equilateral triangle. The speakers should be positioned approximately 6 –
10 feet (1.8 – 3 m) apart. The ideal distance from the rear wall varies depending on the speaker (see list below), however, for optimal performance they need to be a minimum of 3 feet (91 cm) from the side walls.

NOTE: These are recommended distances for optimal performance. Actual results will vary depending on room size and construction.
Experimentation is strongly advised when initially setting up the speakers, as environment and personal preference differ with every installation. If there is insufficient bass, for example, try moving your speakers closer to a wall. The opposite approach is recommended if there is excess bass. Also see the information in the Port Bungs section. If stereo imaging is being lost, try ‘toeing’ them in slightly. The sound should appear to originate from the center point between the speakers, not the actual speakers themselves.

AV Positioning

Please refer to the illustrations below for the ideal angles and positions of each speaker in your surround system. The speakers should be distanced from the wall according to the requirements of the speaker, which are listed in the 2-Channel Positioning section.
If the sound is too bass-heavy or there is a bass boom from the room when playing music (without a subwoofer), try moving the loudspeakers slightly further away from the wall(s). If this is not possible, then try the supplied port bungs. In a system with a subwoofer try adjusting the crossover frequency settings for the speakers and/or subwoofer or changing the subwoofer’s position.

The Bronze C150 center speaker should be positioned so that it is pointing at the approximate ear height of the main listening position. Included with the Bronze C150 are 4 adhesive feet, stick these to the bottom of the cabinet for protection and to help isolate the speaker.
NOTE: Images are for illustrative purposes only. If using the Bronze FX please refer to the ‘Setting Up the Bronze FX’ section for further information.
A.Side surround speakers
B.Rear surround speakers
A 7.1 surround system will make use of side (position A) and rear speakers (position B). If setting up a 5.1 system you can place your surroundings in position (A) or (B).

Setting Up Bronze FX

The Bronze FX features Di-Pole or Bi-Pole listening modes. In Bi-Pole mode, both the driver and tweeters are all in phase. In Di-Pole mode the tweeter on one side of the speaker is out of phase to the other tweeter and driver to create a diffused sound. The FX speakers should be wall-mounted approximately 2 feet above ear height.

Di-Pole/ Bi-Pole switch: When used as part of 5.1 systems as a rear speaker, set the switch to Bi-Pole.
Although there is nothing wrong with experimenting and trying the switch in the Di-Pole mode.

If part of a 7.1 system with 1 pair of Bronze FX’s set the switch to Di-Pole. If using 2 pairs of Bronze FX’s for side and rear effects, set them all to Di-Pole mode and swap the left and right-handed side Bronze FX’s. Keep the rear Bronze FX’s handled correctly as illustrated here.
NOTE: Before adjusting any switches, please ensure that the amplifier is switched off. This will help to protect the amplifier.

Atmos

In-Ceiling

When arranging the overhead channels in an Atmos system we would recommend using our three-way in-ceiling speakers. These employ a unique pivoting midrange/ tweeter module which offers a wider dispersion characteristic and is ideal for Atmos duties. More information can be found on our website: monitoraudio.com
Please see below for the ideal positioning of 2 or 4 Atmos speaker setups.

Bronze AMS Dolby Atmos® enabled speakers

Our new Bronze AMS speakers offer a dedicated solution and alternative to in- ceiling Atmos installations. They can be positioned directly on top of the front and/or rear speakers in a 2 or 4 Atmos speaker setup. Additionally and alternatively, the Bronze AMS can also be wall-mounted for use as surround or height speakers.

Fixing Bronze FX & Bronze AMS to a Wall

CAUTION: Always determine where the Bronze FX or Bronze AMS will be fixed and the structure of the wall. For safety reasons, if unsure of your ability to provide a secure and safe fixing, do not attempt to fix these speakers to a wall. Instead, please obtain the services of a competent and qualified tradesperson.
CAUTION: Ensure that water pipes or electricity cables do not run behind where the speakers are going to be secured. Work from secure steps and avoid trailing wires.
NOTE: We do not supply wall-fixing screws and plugs with the Bronze FX or Bronze AMS. Please only use suitable fixings for the type of wall construction the speakers will be fixed to.
The Bronze FX and Bronze AMS come with keyhole inserts. To fix the speakers to the wall, we would recommend using the wall fixing template enclosed within the packaging carton.

Wiring

Single Wiring

Single wiring is achieved via a single set of cables to the terminals on the back of the loudspeaker. Internally the loudspeaker crossover guides the frequencies to the appropriate driver/tweeter. Low frequencies to the bass drivers, mid frequencies to the mid/bass drivers, and high frequencies to the tweeter.
It is perfectly acceptable to connect to the top, bottom terminals, or even diagonally (experimentation is advisable to achieve the preferred results).

NOTE: When using this method you must keep the terminal links in place.

Bi-Wiring

Bi-wiring is accomplished by connecting separate pairs of speaker cables to the terminals on the loudspeaker from a single pair of connections on the amplifier. In the case of the Bronze Series, the bottom terminals connect to the bass driver(s) and the top terminals connect to the tweeter in 2 way loudspeakers, or the mid and tweeter in 2.5 way loudspeakers.

NOTE: When using this method the terminal links MUST be removed.

Bi-Amping

Bi-amping is the same as bi-wiring except you are introducing a second amplifier into the equation.
In order to bi-amp, you must connect a set of speaker cables to the top terminals on the loudspeaker from one amplifier and another set of speaker cables to the bottom terminals from the second amplifier.

NOTE: When wiring this method the terminal links MUST be removed.

The Effects of Bi-Wiring and Bi-Amping

Fundamentally a loudspeaker crossover varies the impedance seen by the speaker and by the power amplifier. When a full-range audio signal is applied to the terminals of a full-range speaker system, the bass driver(s) will only receive low-frequency signals, the mid driver receives the mid-band frequency signals and the tweeter only gets sent high-frequency signals.
This means that if separate speaker cables are connected to the low and high- frequency terminals, not only have the drive units had the frequency directed and divided for them, but if using a bi-wire set up the two separate speaker cables will now also carry different signals due to the impedance. So the bass cables carry mostly the low frequencies, and the tweeter cable mostly the highs.
The effects of bi-wiring are subtle and depending on the cable construction and design it could be better to go for one better-engineered cable than two for bi-wiring. Monitor Audio recommends experimenting with both configurations to find out which one works best in your system.
Bi-amping adds an additional amplifier to the system so that one amplifier drives the low frequencies and the other amplifier drives the high frequencies. Bi-amping can therefore present a ‘cleaner’ signal at both the low frequency and high-frequency speaker terminals, and because the high and low frequencies have already been separated, each has a minimal effect on the other – in essence, the bass has less effect on the delicate treble. In order to best take advantage of bi-amping, the amplifiers should be as independent of each other as possible. For instance, if using two stereo amplifiers you should use one stereo amplifier for the bass and the other for the treble, minimizing the impact of the bass on the treble.

Port Bungs

WARNING: Care must be taken not to insert the port bungs too far into the port, as this may result in the foam bung being lost inside the cabinet.
If the loudspeaker is to be installed in a small room, typically 9 sqM (80 sqFT), or a room known to reproduce an accentuated bass response, it may be desirable to fit port bungs. However, experimentation is recommended with the positioning of the loudspeaker in the room prior to fitting. To optimize performance from the loudspeaker it is important to ensure the loudspeaker is not positioned too close to a wall or near the corners of a room.
If the positioning of the loudspeaker is predetermined by room aesthetics or layout, you find you have accentuated bass or in the case, speakers are to be sited in close proximity (less than the minimum suggested distances shown in the 2 Channel Positioning section) to a rear wall (such as on a bookshelf, positioned in a cabinet or on a stand close to a wall), we recommend fitting port bungs to the ports. This will reduce the bass ‘boom’ sometimes termed as overhang, and assist the loudspeakers to reproduce their best performance under these environmental conditions. ‘Boom’ is generally caused when bass energy from the loudspeaker ‘excites’ room modes and causes an accentuation at a particular frequency or a number of frequencies.
When fitting port bungs the overall bass extension will not be reduced, however bass energy/ output around the port tuning frequency will be reduced. This has the effect of reducing bass ‘boom’ while increasing bass clarity and apparent agility.
In all circumstances, experimentation is highly recommended.

Running-In Your Speakers

Run your speakers in by playing music at low-mid listening levels for approximately 50-70 hours of playtime. You may find the sound will continue to improve even after the 70-hour mark.
This can be done naturally over time: like a fine wine, the performance will improve with age.
Alternatively, if you wish to run the speakers continuously on the loop you can decrease the audible volume/presence by placing the speakers face-to-face so that the rivers/tweeters are directly aligned and as close as possible. Then connect the amplifier to your speakers so that one is as normal (in- phase): positive to positive and negative to negative (red to red and black to black), and the other speaker out of phase: positive to negative and negative to positive inputs on the speaker.

Retention Bolt Adjustment

The Bronze Series has a bolt-through driver fixing to reduce cabinet coloration. Each bolt acts as a rigid brace, but also removes the need for conventional driver fixings as well, effectively decoupling the driver and front baffle to eliminate a further source of resonance.
NOTE: Should this bolt become loose over time, or has worked loose during transit, then please use the supplied hex key to tighten the bolt back up. This only needs to be a quarter turn after the strain has been taken by the bolt.
