chapter 1 Introduction Thank you for choosing M-Audio® Studiophile® DSM active reference speakers. Features This guide provides installation and operation instructions for the M-Audio DSM2 speaker. DSM2 speakers have the following features: DSM2 speakers feature high-end design elements and precision control circuitry, engineered to provide exceptional tonal accuracy, clarity and dynamic range in a wide variety of applications.
Inputs Drivers M-Audio DSM2 speakers allow analog or digital inputs. Input type is selectable with the Input Select switch on the back panel of the speaker. Each input type has two available connectors. LF Driver DSM2 speakers have an 8-inch LF driver with a steel frame and single-piece anodized aluminum diaphragm. Analog Inputs The analog input signal is sampled on input and processed digitally until it reaches the power amplifier stage.
chapter 2 Overview of the DSM2 Speaker This chapter describes the connectors, controls and features of the DSM2 speaker. Back Panel Connectors and Controls Analog Input (XLR) Analog Input (TRS) Bass Reflex Port Analog Input Sensitivity switch Digital Input (S/PDIF) Digital Thru (S/PDIF) Digital Input (AES/EBU) Volume Trim knob Digital Channel Assignment switch Input Selector switch EQ Setting switches Voltage selector Power switch AC connector Fuse holder Figure 1.
Power Connections AC Connector and Power Switch The AC connector accepts a standard modular AC power cord. One power cord is included with your speaker. Use the Power switch to turn the speaker on or off. Digital Standby Activates the digital inputs of the speaker, but automatically puts the speaker in a low-power standby mode when the digital clock signal is lost for more than one second (for example, when the digital source is powered off).
Digital Inputs EQ Settings The DSM2 speaker provides an AES/EBU Digital In connector as well as S/PDIF Digital In and S/PDIF Digital Thru connectors. The DSM2 speaker has a series of 12 switches for setting the following EQ controls: The digital inputs accept sample rates of 44.1, 48, 88.2, 96, 176.4 and 192 kHz (+/– 10 percent) at 16-bit or 24-bit resolution. Only one digital input connector (AES/EBU In or S/PDIF In) may be used at a time.

chapter 3 Setup and Operation This chapter provides instructions for placing, connecting and configuring DSM2 speakers. Setting Up the Speakers Correct placement, connection, and configuration ensures optimal performance and safe operation of your speakers. Speakers should always be placed to provide balanced, accurate sound in your preferred mixing position. The exact location depends on the size and acoustics of the environment where you are using the speakers.
Speaker Orientation Stereo Positioning For the best sonic results, DSM2 speakers should be set in a vertical orientation. Vertical placement minimizes the effects of interference between the drivers and provides the largest horizontal (side-to-side) listening window as well as the most stable and consistent frequency response and imaging. The following diagram shows the recommended setup for stereo monitoring. 0.
Configuring and Connecting AC Power Be sure to follow the instructions in this section for the proper configuration of fuses and voltage settings. DSM2 speakers must be manually configured for the voltage in your area. Always check the voltage setting and fuse rating, as described below, before connecting and powering your speakers. Installing a Fuse A 2.5 Amp fuse is required for both the 100–120V or 220–240V settings. Make sure to use a fuse rated at 2.5 Amps.
Connecting Power Connecting Audio To connect power to the speakers: 1 Make sure you have set the Voltage Selector This section explains how to make analog and digital audio connections to DSM2 speakers. and installed the proper fuse before proceeding. (See “Setting the Voltage” on page 9 for details.) Connecting Analog Inputs 2 Connect the included AC power cord to the AC connector on the back panel of each speaker (one power cord is included with each speaker).
Connecting Digital Inputs The Digital Thru S/PDIF port on this speaker is then connected to the Digital In port on the other speaker to supply it with its digital audio input. S/PDIF Input S/PDIF Input S/PDIF Thru Digital Input (AES shown) S/PDIF Thru AES/EBU Input Digital input section DSM2 speakers accept digital input at the AES/EBU Digital Input (XLR connector) and the S/PDIF Digital Input. Only one digital input connector (AES/EBU In or S/PDIF In) may be active at a time.
To connect a digital source: 1 Do any of the following: Configuring Speaker Settings • Connect an AES cable (XLR) to the AES/EBU In port on the back of a speaker. Volume Trim Settings • Connect a S/PDIF digital cable to the S/PDIF In port on the back of a speaker. The Volume Trim control lets you match the input sensitivity of speaker to the source. 2 Connect the other end of the cable to the digital audio source (for example, a digital output from an M-Audio interface).
EQ Settings Setting the Mid-Range EQ The EQ controls on DSM2 speakers let you adjust the response of the speaker to match your monitoring environment and studio equipment. For EQ frequency graphs for each of these settings, see “Reference Diagrams” on page 18. The Mid-Range EQ lets you compensate for midrange resonance or damping that may be created by speaker placement or room acoustics. It offers a low-Q (wide bandwidth) boost or cut.
Setting the LF Shelf EQ Setting the High-Pass Filter Your choice for the LF Shelf setting depends on where you place the speakers within a room. The High Pass Filter lets you adjust the bass rolloff of your DSM2 speakers. Start with the filter all the way open (40 Hz setting) and only raise the cutoff frequency in order to protect the LF drivers at low frequencies, or to couple your DSM2 speakers with a subwoofer.
To adjust the Desktop 220 Hz Filter: To adjust the Desktop 200 Hz Filter: Set switches 9 and 10 to the positions shown below to activate the corresponding EQ levels.

Troubleshooting The LED located on the front of the unit indicates the following states of operation. Front Panel LED States LED State Indication Blue Analog Input Digital Input: Lock Yellow Digital Input: No Lock Blue (flashing) Digital Standby Mode Red Clipping Red (flashing) Hardware failure If the LED is lit solid blue and there is no sound, do the following: Check that the unit is receiving an analog signal or valid digital signal. Check the temperature of the rear metal panel.
