[. . . ] Crossover The crossover function is handled by a digital processor that ensures flat, distortionfree integration of the LF and HF drivers. EQ and Placement Settings Six filters allow for customization of speaker response to a variety of sonic conditions and speaker orientations in your studio. Digital Channel Assignment When working with digital input, this switch is used to select the channel to be monitored in the speaker. Signals may be sent to the two analog input connectors at the same time. When two analog input signals are present, they are summed. Fuse The fuse protects components of the DSM2 speaker from being damaged by electrical underor over-powering, spikes, and other anomalies. A 2. 5 Amp fuse is required for both the 100­120V and the 220­240V settings. XLR Connector The XLR Analog In connector is balanced. (If the signal source is unbalanced, connect the unused pin to ground. ) Make sure to use a fuse rated at 2. 5 Amps. Do not use fuses of any other rating, or you risk damage to the unit Inputs Input Selector Switch The input selector switch selects between the following input states for the speaker: Analog Activates the analog inputs of the speaker. Digital Activates the digital inputs of the speaker. 1/4-inch TRS Connector The 1/4-inch TRS Analog In connector is balanced. (If the signal source is unbalanced, connect the unused pin to ground. ) Analog Input Sensitivity Switch The analog input operating level can be switched between ­10 dBV and +4 dBu. This setting applies to both the XLR and 1/4-inch TRS analog inputs. For information on the appropriate operating level for your audio source, see the manufacturer's specifications. 4 M-Audio Studiophile DSM2 Guide Digital Inputs The DSM2 speaker provides an AES/EBU Digital In connector as well as S/PDIF Digital In and S/PDIF Digital Thru connectors. 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. EQ Settings The DSM2 speaker has a series of 12 switches for setting the following EQ controls: High-Frequency Shelf Sets an adjustable high frequency boost or cut using a built-in HF shelftype EQ. Mid-Range EQ Sets an adjustable midrange frequency boost or cut using a built-in peak/notchtype EQ. Low-Frequency Shelf Sets a low frequency cut using a built-in LF shelf-type EQ, which lets you tune the speaker's bass response to fit your monitoring environment. High-Pass Filter Sets a high-pass type EQ, which lets you establish the lower limit of the speaker's frequency response. Desktop 220 Hz Cuts around a center frequency of 220 Hz using a built-in notch-type EQ, which lets you compensate for the effects of frequency buildup when your DSM2 speaker is placed on a reflective surface. Desktop 175 Hz Cuts around a center frequency of 175 Hz using a built-in notch-type EQ, which lets you compensate for the effects of frequency buildup when your DSM2 speaker is placed on a reflective surface. Desktop 200 Hz By using both the Desktop 220 Hz and the Desktop 175 Hz settings, you can cut around a center frequency of 200 Hz to compensate for the effects of frequency buildup when your DSM2 speaker is placed on a reflective surface. AES/EBU Digital In The AES/EBU digital input is a female XLR connector. S/PDIF Digital In This S/PDIF connector is for connecting digital audio from a S/PDIF source device, or from the S/PDIF Thru connector of another DSM2 speaker. S/PDIF Digital Thru This S/PDIF connector passes digital input from either the AES/EBU Digital In or the S/PDIF Digital In connector to the S/PDIF Digital In connector of another DSM2 speaker. Digital Channel Assigment The DSM2 speaker has a digital channel assignment switch that lets you monitor the left channel, right channel, or a summed (mono) mix of the left and right channels of the digital input. Volume Trim Control The Volume Trim control adjusts the level of the input signal in the digital domain. Trim values range from ­22 dB to +10 dB. Chapter 2: Overview of the DSM2 Speaker 5 Front Panel LED indicator Front panel of the DSM2 Front Panel LED The LED indicator on the front of the DSM2 speaker indicates the following states: Front Panel LED States LED State Blue Indication Analog Input Digital Input: Lock Digital Input: No Lock Digital Standby Mode Clipping Hardware failure Yellow Blue (flashing) Red Red (flashing) 6 M-Audio Studiophile DSM2 Guide chapter 3 Setup and Operation This chapter provides instructions for placing, connecting and configuring DSM2 speakers. Correct placement, connection, and configuration ensures optimal performance and safe operation of your speakers. Setting Up the Speakers Speakers should always be placed to provide balanced, accurate sound in your preferred mixing position. [. . . ] ­3. 0 dB If you've mounted your DSM2 speakers on stands in a corner, set the LF Shelf to ­3. 0 dB, which activates a shelving filter to reduce the low-frequency buildup. ­4. 5 dB If you've mounted your DSM2 speakers on a meter bridge (or other reflective surface), as well as in a corner, set the LF Shelf to ­4. 5 dB, which activates a shelving filter to reduce the low-frequency buildup. To adjust the LF Shelf EQ: Set switches 5 and 6 to the positions shown below to activate the corresponding EQ levels. 5 6 ON OFF OFF ON ON ON OFF OFF Setting the High-Pass Filter 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.
