Product Overview
DSP-based Loudspeaker Management Processor
BSP - 408
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 loudspeaker 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 convenience of user and intuitive GUI-based main control PC program supports users to set up the device as their
will via network.
■

① Main Power Unit
Turn the device power on/off. AC main input to the universal switched mode power supply, operates 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.
07
⑦ Digital Input terminal
Receives AES/EBU digital input signal. This connection is wired like the audio analog connection,
but we recommend the use of the proper thress conductor, 110-Ohm, twisted pair cable.
⑧ Digital Output terminal
Send AES/EBU digital output signal.
⑨ USB Control terminal
Connect USB terminal to PC and allows setup device function by PC control program.
