Product property
■ Product Overview
DSP-based Loudspeaker Management Processor
BSP series is digital loudspeaker processor of professional sound market and designed based on 40bit Float-
ing Point DSP chip and high-quality converter of 96KHz and 24bit. BSP series provides 31 band graphic
equalizer, 9 band parametric equalizer, X-over (crossover), limiter and other different functions for loudspeak-
er management. Especially for X-Over function, it offers differentially Advanced FIR of excellent fabric property
which satisfies linear phase, as well as the conventional IIR digital filter to support excellent sound which
minimizes mutual interference between speaker units. Besides, touch-based LCD panel maximizes the con-
venience of user and intuitive GUI-based main control PC program supports users to set up the device as their
will via network.
■ Main Features
1) DSP-based powerful sound processing function
- support 4 channel analog and digital (AES/EBU) input and 8 channel analog and digital (AES/EBU) output
- 96 KHz Sampling Rate and high-function 24-bit A/D, D/A converter
- 31 Band graphic equalizer (both for input and output channel)
- 9 Band parametric equalizer (support Bell, Low Shelf, High Shelf)
- Various IIR filters (Bessel, Butter-Worth, Linkwitz-Riley)
- Provide linear phase FIR filter
- Phase set-up function
- Wide delay control range up to 1300msec (both for input and output channel)
- Provide limiter function (automatic control of the output signal level below the threshold level which the user
set up)
2) Convenience for use
- Save and load function up to 50 Preset set-ups and support one-click application of frequently used set-up
value
- 3.5 inch LCD touch screen and graphic UI are provided at the device for convenience of operation
- Provide various connecting terminal for device set-up control (both ETHERNET and USB connection)
- Main PC software provides intuitive identification of set-up status details on the main page.

① Mode Buttons
There are three keys:
•METER Key: show the information of gain and routing status
•MENU Key: go to menu screen for device’s parameter set-up
•ESC Key: move to previous menu
② 3.5” Touch LCD Display
Integrated 3.5” color touch screen LCD with backlight, controls setup and operation. The LCD control
screen and its controls let the user adjust the configuration of unit and variable function parameters.
③ Rotary Encoder Wheel
Move to menu or edit parameter data values. When you edit a parameter, press the center of wheel to
confirm it after you finish editing.
④ Input Signal Level Indicators
Indicate the current input peak level of signal. The red segment indicates that the channel’s signal reaches
the one set of audible clipping, which should avoid by adjusting the input level.
⑤ Output Signal Level Indicators
Indicate the current output peak level of signal. The red segment indicates that the channel’s signal reach-
es the one set of audible clipping, which should avoid by adjusting the output level.
⑥ Mute On/Off Buttons
Mute or Un-Mute input and output channels. When an each channel is muted, a blue LED will come on for
indication.

① Main Power Unit
Turn the device power on/off. AC main input to the universal switched mode power supply, op-
erates over a wide range of AC input voltages from 100V to 240V, 50/60Hz. Main Fuse is located
in a finger-proof holder adjacent to the mains inlet and its spec is 2.5A-250V.
② Control Input
The control input (Normal Open type) can be used to receive signals from third party equipment
that must trigger actions. This control input can also be used for audio mute action with emer-
gency alarm equipment.
③ MGMT Ethernet Port
This Ethernet Port is a standard RJ45 CAT5 connector, used for transmission of remote control
data over long distance or multiple unit applications and allows setup device function by PC
control program. MGMT In & out Ports allow daisy-chain connection of multiple unit.
④ RS-232 Control Port
Used for system condition checking for only special engineers.
⑤ Balanced XLR Analog Input
Received electrically balanced audio signal, locking XLR connector
⑥ Balanced XLR Analog Output
Output electrically balanced audio signal to the system’s amplifiers.
