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. 

Voltage Selector

Before connecting a DSM1 speaker to a power 
source, make sure the Voltage Selector setting 
matches your local voltage (100–120V or 
220–240V). 

Fuse

The fuse protects components of the DSM1 
speaker from being damaged by electrical under- 
or over-powering, spikes, and other anomalies. 

A 2.5 Amp fuse is required for both the 
100–120V and the 220–240V settings.

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. 

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). When the clock signal is restored, the 
speaker wakes up from standby mode. 

Analog Inputs

The DSM1 speaker provides an XLR analog in-
put connector and a balanced 1/4-inch TRS ana-
log input connector. 

The analog input signal is converted to a 
96 kHz, 24-bit digital signal for crossover/EQ 
processing, and converted back to analog just 
prior to the power stage of the driver amplifiers. 

Signals may be sent to the two analog input con-
nectors at the same time. When two analog in-
put signals are present, they are summed.

XLR Connector

The XLR Analog In connector is balanced. (If the 
signal source is unbalanced, connect the unused 
pin to ground.)

1/4-inch TRS Connector

The 1/4-inch TRS Analog In connector is bal-
anced. (If the signal source is unbalanced, con-
nect the unused pin to ground.)

Analog Input Sensitivity Switch

The analog input operating level can be 
switched between –10 dBV and +4 dBu. This set-
ting applies to both the XLR and 1/4-inch TRS 
analog inputs. For information on the appropri-
ate operating level for your audio source, see the 
manufacturer’s specifications. 

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
