MR5mk3 / MR6mk3 / MR8mk3 Introduction MRmk3 Series Powered Studio Monitors love music as much as you do. Subject to an intensive music-centric voicing process designed to connect you to the music, the compact and affordable MRmk3 monitors are specifically designed to enhance the mixing and monitoring experience in any home or project studio. Optimizing features include an enhanced waveguide system for a wider sweet spot and custom-tuned rear porting for smooth, extended bass response.
We realize that you can’t wait to hook up your MRmk3 Studio Monitors and try them out. Nevertheless, please take the time to read this page NOW, and the rest can wait until you’re good and ready. 1. Turn the input level [6] control on the back of the cabinet down (fully counterclockwise) before turning on the monitor for the first time. 2. Set the power switch [2] on the back panel off. This will prevent you from accidentally connecting a hot signal source to the monitor and getting a rude surprise. 3.
MR5mk3 / MR6mk3 / MR8mk3 Rear Panel Description This is where the signal is connected to the monitor and adjustments are made to the frequency response of the speakers to match the monitor’s location and the room’s environment. Press the right side of this switch down to put the speaker into standby mode. It will not function, but the circuits are still live. To remove AC power, either turn off the AC supply, or unplug the power cord from the speaker and the AC supply. 3.
6. Input Level This switch tailors the overall low-frequency response by +2 dB or +4 dB at 100 Hz. The MRmk3 studio monitors expect a line-level signal at its input. Use this control to adjust the sensitivity of the input section according to the signal strength at its input. • For most applications, use the “0 (NORMAL)” setting. This takes the equalization circuit out of the signal path. • If a little extra low-frequency output is necessary, use the +2 dB setting.
MR5mk3 / MR6mk3 / MR8mk3 Protection Circuits There are several protection mechanisms designed into the MRmk3 studio monitors to safeguard the speakers and amplifiers from inadvertent damage. CAUTION: The protection circuits are designed to prevent damage to the speakers under reasonable and sensible conditions. Should you choose to ignore the warning signs (i.e., excessive distortion), you can still damage the speakers in the MRmk3 studio monitors by overdriving them.
Appendix A: Service Information Troubleshooting No Power • Our favorite question: Is it plugged in? • Make sure the power cord is securely seated in the IEC socket [1] and plugged all the way into the AC outlet. • Make sure the AC outlet is live (check with a tester or lamp). • Is the power [2] switch on the rear panel in the ON position? • Is the Running Man logo [8] on the front panel illuminated? If not, make sure the AC outlet is live. If so, refer to “No Sound” below.
MR5mk3 / MR6mk3 / MR8mk3 Repair For warranty service, please refer to the warranty information on page 15. Non-warranty service is available at a factoryauthorized service center.

Service for MRmk3s living outside the United States may be obtained through local dealers or distributors.
Balanced XLR Input Connector Unbalanced RCA Input Connector XLR connectors are used to make balanced connections to the MRmk3 studio monitors. They are wired as follows, according to standards specified by the AES (Audio Engineering Society). RCA-type plugs (also known as phono plugs) and jacks are often used in home stereo and video equipment and in many other applications. They are unbalanced and electrically equivalent to a 1/4" TS phone plug.
