Owner’s Manual
DPM10B 10 Inch 3-Way
Powered Studio Monitor

Thank you for purchasing this Rockville DPM1OB 3-way powered studio monitor.
This powered studio monitor creates a new performance level in studio monitors. Our unique design eliminates high-frequency diffraction while providing full range monitoring accuracy, refined vocal reproduction, and enhanced bass response.
Unlike most studio monitors, the Rockville DPM1OB features a Tri-Amplifier design. The woofer, midrange, and tweeter each have an individual Frequency Optimized Amplifier (FOA). These amps guarantee that there is no wasted energy in the amplification stage and an absolute minimum of harmonic distortion. The efficiency of our class AB design is in excess of 90% with zero discernible hiss or white noise.
This DPM1OB monitor is compatible with most mixing scenarios. It features various input connections (RCA, XLR port, and balanced/unbalanced 1/4-jack) so it can hook up to any mixing/monitoring system or media source.
Please read this installation guide carefully for proper use of your Rockville DPM1OB 3-way powered studio monitor. Should you need technical assistance during or after your installation please call our technical helpline at 1-646-758-0144, Monday through Thurs- day, 9 am to 10 pm EST., and Fridays, 9 am to 3 pm EST.

IMPORTANT SAFETY INSTRUCTIONS

TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE THE AMPLIFIER PLATE. NO USER-SERVICEABLE PARTS INSIDE. WE RECOMMEND TAKING THE UNIT TO A QUALIFIED SERVICE TECHNICIAN FOR ANY REPAIRS.

• Do not place this monitor on an unstable cart, stand, bracket or table. The monitor may fall, causing serious injury to a child or adult and serious damage to the unit.
• Do not use this monitor near water; for example, near a bathtub, sink, in a wet basement, or near a swimming pool.
• The monitor should be situated away from heat sources such as radiators, heat registers, stoves, or other devices that produce heat.
• This monitor should be connected to a power supply outlet of the same voltage as that which is specified on the amp plate of the unit. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where it exits from the unit.
• Clean only with a soft damp cloth. Unplug this product from the wall outlet before cleaning.
• Upon completion of any servicing or repairs, request the service center/shop uses factory authorized replacement parts. Replacement with unauthorized parts may result in fire, electrical shock, or other hazards.

Positioning

The mid-field monitor, by definition, reduces room interaction. This can be compared to the conventional stereo configuration or the large monitor arrangement in a recording studio where sounds emanating from the monitor or reflecting off ceilings, walls, and floors, all greatly affect sound quality.
By shortening the path to the ear, the DPM1OB powered monitor offers a tremendous amount of flexibility allowing sound to become less susceptible to differing room conditions. The ability to adjust the high/low-frequency characteristics is equally important to help compensate for room irregularities and achieve the best performance.
Placing the monitor close to a wall or in a corner will reinforce low frequencies. If you move it 2 to 3 feet from walls and corners, you’ll hear less low-frequency interaction.
The monitor should be placed so that the listening position is fully covered with all units resting on the same horizontal plane. For testing and break-in, we recommend acoustical music because it represents a wide, natural spectrum of sound.
Initial placement starts by measuring out a simple equilateral triangle (all three sides equal in length) with the apex at the center of the listening position (as shown below). In this configuration, the left and right monitors are each placed at a 60° angle, equidistant from the listening position.

Subwoofer Placement (Optional)
Placement is for the most part a trial and error process and differs depending on the shape and size of the room. Use the diagram below as a general starting point for placement.
Place the sub on the floor in front of the listening position. Be sure to place it centered between the monitors. Then try different locations throughout the room until you find a location that suits your needs. If possible, place the subwoofer in a corner as this will provide you with lower distortion, increased headroom, and increased efficiency.
Ensure the proper phase settings on your subwoofer. Then adjust the subwoofers lowpass filter so that it blends seamlessly with your DPM1OB monitors. When you have finished adjusting the phase and cross-over settings, re-adjust the level of the sub to your personal preference.

Amplifier Functions

1. High Frequency Level control: -2dB to 1dB
2. Low Frequency Level control: -2dB to 1 dB
3. Master volume control
4. XLR input: designed to suit a wide range of balanced and unbalanced signals.
5. 1/4-TS/TRS input: accepts balanced and unbalanced 1/4-plugs. It accepts signals from a variety of sources such as keyboards, electronic drums, tape recorders, mixers, etc. When you use an unbalanced 1/4-plug, the line input automatically turns the ring into the ground.
6. RCA input jack

Troubleshooting

power indicator is illuminated.
2.   Check that AC voltage matches that of the operating voltage requirements.
3.   Check fuse, replace if necessary (see page 10). REPLACE FUSE WITH ONE OF THE SAME TYPE AND RATING.
No sound/ distorted sound| 1.   Check to see if all other audio devices using the same outlet are still operating.
2.   Ensure that the audio source cable is plugged into both the source and the corresponding monitor input.
3.   Check that unit volume is not set to 0.
4.   The signal source (mixer, workstation, MP3 player, etc.) is turned up to a level that can properly send a signal to the moni­tors.
5.   Check each monitor individually for sound. Ensure that the input cables are properly seated.
6.   If the monitor is still not responding, it should be returned to an authorized Rockville dealer.
Buzzing sound| 1.  Make sure you are using a proper cable. For 1/4″ cables, there are three types: instrument, TS (unbalanced), and TRS (balanced). Check the requirements of the connected gear and the input of the speaker and make sure you are using the appropriate cable.
2.  All audio equipment should use the same ground point. Check all other devices using the same AC output in the building such as dimmers, neon signs, TVs, and computer monitors. These devices should not be using the same circuit.
