Introduction
Thank you for purchasing this high quality Citronic digital speaker management system. The aim of our audio
processing range is to offer cost-effective, high performance sound sculpting tools for live sound
reinforcement and installation applications. The Citronic DSM2-6 offers a comprehensive and professional
speaker management solution delivering unsurpassed sound quality.
The DSM2-6 comprises a 2 input, 6 output digital sound processor with fully assignable high and low pass
crossover filters on each output for low or high frequency outputs or in combination for mid frequency
output. Each filter can be assigned as Butterworth, Linkwitz-Riley or Bessel type across various cut-off slopes
to give ultimate flexibility.
Each input channel has gain and phase correction and 6 bands of independent parametric or shelving EQ to
tailor the input tone.
Each output channel has 6 bands of independent parametric EQ for tone shaping and to compensate for
room or speaker anomalies. Also, each output has time alignment delay and adjustable limiter to protect the
outputs from overloading.
In addition to the user-friendly front panel menus, all functions may be manipulated and stored via USB using
the included PC software. A graphic interface allows quick and easy adjustment of all the main parameters.
Further slave DSM2-6 units can be linked via RS485 connection (RJ45)
Signal connection is XLR throughout, balanced or unbalanced and each output may be addressed from either
input A or B or A+B combined.
The internal memory can store up to 30 user programs and each can be named for easy identification. Each
can be recalled at will and the unit can be password protected to lock out the functions to unauthorized
persons.
This unit has been built to Citronic’s exacting standards using high grade circuit boards and components
housed in a heavy duty steel chassis casing to give long term, reliable service.
Installation
Set the DSM2-6 into a 1U space in a rack, ensuring enough depth to contain the unit and any connectors
attached to it. Secure the front panel with rack screws and nuts to hold in place and stop the unit slipping.
Plug the included power cable into the rear panel IEC connector and connect to the mains. Be sure to switch
the DSM2-6 on before switching on the power amplifiers to avoid loud thumping sounds through the
speakers and switch the amplifiers off before switching off the DSM2-6.
Connection to each channel is served by XLR for both inputs and outputs.
