midiplus MS Series Active Studio Monitor
Introduction
Thank you for choosing MS series active studio monitors. This 2-way active monitoring system consists of a silk dome tweeter and carbon fiber cone woofer, along with an efficient Class-D power amplifier. It provides a neutral tool for recording engineers and producers to analyze recordings and optimize mixing. The MS series studio monitors has three inputs: balanced XLR, 1/4″ Jack, and unbalanced RCA, as well as Bluetooth connectivity. This makes it suitable for use in both large recording studio and home studio. To ensure proper use and understanding of the monitors, please read the manual carefully and keep it in a safe place for future reference.

- 3 Logo LED: The two colors LED indicators the monitor’s power and Bluetooth status.
NOTE: Rapidly turning the power switch ON and OFF may cause the device’s electronics to malfunction. It is recommended to wait for at least 3 seconds after turning the power OFF before turning it ON again.
Connection
The monitor features balanced XLR, 1/4″ Jack, and unbalanced RCA inputs, as well as Bluetooth connectivity. To ensure optimal sound quality, use high-quality cables of the shortest length possible. Longer cables increase the chance of noise interference. Balanced cables are more resistant to noise than unbalanced cables.
NOTE: Always turn the power off before inserting and unplugging the cable.
XLR Input
The XLR input is use for balanced connection. The XLR connector is wired as follows:
1/4″ Jack Input
The 1/4″ jack input accepts both balanced TRS and unbalanced TS. The balanced TRS connector is wired as follows:
The unbalanced TS connector is wired as follows:
NOTE: The XLR and 1/4″ jack input connectors can not be used simultaneously.
RCA Input
The RCA input is an unbalanced connection. The RCA connector is wired as follows:
Bluetooth Connectivity
The MS series monitors features Bluetooth with True Wireless Stereo (TWS) Technology. You can play stereo music on two MS monitors via Bluetooth.
True Wireless Stereo Pairing
- Turn on both monitors.
- Press and hold the Bluetooth button on both monitors for 1 second to activate Bluetooth, you will hear a notification sound from the monitor, the front logo LED will alternate between white and ice blue.
- If your monitor is connected to a Bluetooth device, disconnect it and ensure that it is not connected.
- To pair TWS first time, double-click the Bluetooth button on the monitor you have selected as the left channel. Both monitors will emit a notification sound once the pairing is successful. The logo LED on the right channel monitor will turn blue, while the left channel monitor will alternate between white and ice blue. These monitors will automatically pair when Bluetooth is turned on next time.
NOTE: If a monitor is connected to a phone before the TWS is paired, it will be considered the left channel. If both monitors are connected to a phone, the TWS cannot be paired. Please ensure that you pair the TWS before connecting it to a phone.
Bluetooth Pairing
On your phone or another Bluetooth device, find the “MS Audio” in the list of available devices and connect to it. The monitors will emit a notification sound once the monitor is connected. The front logo LED will turn blue.
Reset Bluetooth Connections
To reset the Bluetooth connection, press and hold the Bluetooth button for at least 5 seconds. At this point, you can reconnect the TWS and Bluetooth devices.
Frequency Response Trim Switches
The MS monitors’ high-frequency and low-frequency responses can be adjusted up to l.SdB in either direction to match your room’s acoustic characteristics.
LF TRIM: Adjust the low-frequency response. Setting attenuates or boosts the range below 800 Hz by l.SdB. The [0dB] position produces a flat frequency response. HF TRIM: Adjust the high-frequency response. Setting attenuates or boosts the range above 5 kHz by l.SdB. The [0dB] position produces a flat frequency response.
