Frequently Asked Questions - MPS2 Bogen

How do I select the power tap on the MPS2?

Rotate the Power Tap Selector switch on the rear of the speaker until the desired power level (32, 16, 8, 4, 2, or 1 watt) lines up with the arrow. Ensure the switch is not set to 16Ω when using a 70V system.

Can I use the MPS2 with a low-impedance amplifier?

Yes, set the Power Tap Selector to 16Ω and connect directly to a low-impedance amplifier output. Ensure the total load impedance of all parallel speakers does not fall below the minimum rating of the amplifier, and that the amplifier power does not exceed the speaker's maximum rating of 50W.

What is the maximum number of MPS2 speakers I can connect to a 70V amplifier?

The sum of all power tap settings must not exceed the amplifier’s output power. For example, five speakers at 16W each total 80W, requiring at least an 80W amplifier.

How should I suspend the MPS2 pendant speaker?

Use a main drop cable attached to the Main Drop Cable hole and a separate safety cable attached to the Safety Cable hole. Both cables and anchor points must be rated for at least 100 lbs. The safety cable should have slight slack and not bear direct weight.

Can the MPS2 be used outdoors?

No, the MPS2 is not an outdoor speaker. Do not expose it to rain or moisture. It is designed for indoor use only.

What is the warranty period for the MPS2?

Bogen warrants the MPS2 to be free from defects in material or workmanship for two (2) years from the date of sale to the original purchaser. The warranty covers normal installation and use.

How do I clean the MPS2 speaker?

Use a soft, dry cloth to gently wipe the exterior. Avoid water, solvents, or abrasive cleaners. Do not allow moisture to enter the grille or enclosure.

What type of cable should I use for suspension?

Use wire rope or other drop line rated for at least 100 lbs. If using clad cable, strip away any coating so the clamping device contacts bare wire cores.

What is the difference between MPS1 and MPS2?

The MPS2 has a woofer and coaxial tweeter (two-way) with frequency response up to 22 kHz, while the MPS1 has a single dual-cone wide-range driver with response up to 14 kHz. The MPS2 also has higher sensitivity (87 dB vs 86 dB) and is slightly heavier (5 lb vs 4 lb 8 oz).

Can I replace the snap-lock input plug?

Yes, the snap-lock input plug is included with the speaker and can be replaced using an optional hanging cable kit (CK10, white or black) if needed.

Installation and Use Manual

Power Tap Selection

16-ohm or 70V

The Power Tap selector switch is used to set the appropriate power level or impedance for your system. Rotate the switch until the power level you require lines up with arrow.

IMPORTANT: When connecting to a 70V amplifier, make sure that the Tap Selector switch on the speaker IS NOT set in the “16Ω” position.

Speaker Connection and Polarity

Speaker wiring is terminated at a snap-lock input connector, with a positive and negative terminal. All wiring should be done prior to installation and then plugged into the rear of the speaker. Wire all speaker polarities the same way.

70V System Configurations

When designing a 70V system, the total of all power tap settings of all the connected speakers CANNOT EXCEED the output power of the 70V amplifier (amplifier power can exceed the sum of the speaker loads).

EXAMPLE: 16 + 32 + 8 + 8 + 16 = 80 Watts minimum amplifier output rating.

Low-Impedance System Configurations

When wiring together multiple MPS1/2 speakers that are set to 16 ohms, it is important to calculate (using Ohm's Law) the total load that these speakers present to the amplifier. The total load impedance of the interconnected speakers cannot be lower than the minimum load impedance rating of the low-impedance amplifier. Also, care must be taken to ensure the amplifier cannot overdrive the speaker's maximum power rating.

EXAMPLE: Four 16-ohm speakers in parallel = 4 ohms. Also in this example, the amplifier output power rating capability should not exceed 200W (4 X 50W, the MPS1/2).

MPS1/2 Speaker Cable Connections and Suspension Instructions

In addition to the Main suspension Drop Cable, a backup Safety Cable is required for proper installation. Use wire rope or other drop line rated for at least 100 lbs. to ensure a proper safety margin. The attachment point on the structure from which the speaker is to be anchored also must be able to handle 100 lbs.

NOTE: If using suspension cables with a cladding, be sure to strip away any coating so that clamping device being used will be pressed in direct contact with the bare wire cores.

NOTE: ALONG WITH THE MAIN DROP CABLE, YOU MUST ALSO USE A SAFETY CABLE WHEN SUSPENDING AN MPS1/2 PENDANT SPEAKER. BE SURE TO SECURE ALL RIGGING POINTS AND FOLLOW ALL THE CABLE MANUFACTURER'S MATERIAL RECOMMENDATIONS & INSTALLATION INSTRUCTIONS. FAILURE TO DO SO MAY RESULT IN PROPERTY DAMAGE, INJURY OR DEATH, AND LEGAL LIABILITY FOR YOU AND/OR YOUR COMPANY.

Attach the main drop cable to the MPS1/2 Main Drop Cable hole in the Suspension Attachment located on the top of the speaker. This Main Drop Cable will be the primary connection that will hold all the suspended speaker's weight to the anchor point.

Likewise, attach the Safety Cable to the Safety Cable hole in the Suspension Attachment. This Safety Cable is meant to be a safeguard only, so when attaching to an anchor point allow for a small amount of slack in the wire, as the Safety Cable should not bear any of the speaker's direct supension weight to keep the speaker hanging level.

IMPORTANT: The MPS1/2 Mini Pendant is not an outdoor speaker. DO NOT expose the speaker to rain or moisture. The MPS1/2 should be installed by qualified personnel.
