[. . . ] HF Driver DSM1 speakers have a 1-inch HF driver with a soft-dome ferro-fluid cooled design that ensures smooth, accurate reproduction of highfrequency details. Digital Signal Processing DSM1 speakers employ 36-bit digital signal processing for control of crossover, EQ, and channel assignment settings. 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 DSM1 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. For information on the appropriate operating level for your audio source, see the manufacturer's specifications. 4 M-Audio Studiophile DSM1 Guide Digital Inputs The DSM1 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 DSM1 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 DSM1 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 DSM1 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 DSM1 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 DSM1 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 DSM1 speaker. Digital Channel Assigment The DSM1 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 DSM1 Speaker 5 Front Panel LED indicator Front panel of the DSM1 Front Panel LED The LED indicator on the front of the DSM1 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 DSM1 Guide chapter 3 Setup and Operation This chapter provides instructions for placing, connecting and configuring DSM1 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. [. . . ] Start by leaving this switch in the "flat" (0 dB) position, then experiment with different settings to see if you like the results. To adjust the Mid-Range EQ: Set switches 3 and 4 to the positions shown below to activate the corresponding EQ levels. 3 4 ON OFF OFF OFF OFF Setting the High Frequency Shelf EQ The HF Shelf EQ lets you compensate for high frequency variations that may be created by source equipment or room acoustics. Start with the HF Shelf EQ setting "flat" (0 dB) as this provides the most natural high-frequency response. To adjust the HF Shelf EQ: Set switches 1 and 2 to the positions shown below to activate the corresponding EQ levels. 1 2 ON OFF OFF ON ON ON OFF OFF 0 dB +1. 5 dB 0 dB ON ON ON ­1. 5 dB ­3. 0 dB +1. 5 dB Mid-Range EQ switches and settings ­1. 5 dB ­3. 0 dB HF Shelf switches and settings Chapter 3: Setup and Operation 13 Setting the LF Shelf EQ Your choice for the LF Shelf setting depends on where you place the speakers within a room.
