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.

AES/EBU Digital In

The AES/EBU digital input is a female XLR con- nector.

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 Dig- ital In connector to the S/PDIF Digital In con- nector of another DSM1 speaker.

Digital Channel Assigment

The DSM1 speaker has a digital channel assign- ment switch that lets you monitor the left chan- nel, 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.

EQ Settings

The DSM1 speaker has a series of 12 switches for setting the following EQ controls:

High-Frequency Shelf Sets an adjustable high fre- quency boost or cut using a built-in HF shelf- type EQ.

Mid-Range EQ Sets an adjustable midrange fre- quency boost or cut using a built-in peak/notch- type EQ.

Low-Frequency Shelf Sets a low frequency cut us- ing a built-in LF shelf-type EQ, which lets you tune the speaker’s bass response to fit your mon- itoring 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 reflec- tive surface.
