1.0 Introduction
The LSM series is a digital loudspeaker management system designed for
the touring or fixed sound installation markets. The absolute latest in
available technology is utilized with 32-bit (40-bit floating point ) processors
and high performance 24-bit Analog Converters. The high-bit DSP prevents
noise and distortion induced by truncation errors of the commonly used 24-
bit fixed-point devices. A complete set of parameters include I/O levels,
delay, polarity, 6 bands of parametric EQ per channel, multiple crossover
selections and full function limiters. Precise frequency control is achieved
with its 1 Hz resolution. Inputs and outputs can be routed in multiple
configurations to meet any requirement. The LSM series can be controlled
or configured in real time on the front panel or with the intuitive PC GUI
accessed via the USB or RS485. Software upgrade for CPU and DSP via
PC keeps the device current with newly developed algorithms and functions
once available. Multiple setup storage and system security complete this
professional package.

3.0 Front Panel Functions
1. USB – a standard Type B USB connector. Proper device driver must be
installed prior to usage.The red LED will come on for indication will USB
cable connected
2. Mute keys – Mute/Unmute input and output channels. When an input
channel is muted, a red LED will come on for indication.
When Menu Control key is pressed, it selects the corresponding
channel for the LCD menu display which is acknowledged by a green LED
above the button’s. The last modified menu will be displayed on the LCD.
While the Menu Control key is hold down, multiple channels can be
linked or unlinked by pushing the desired channels. This eases
programming the same parameters across multiple channels. Multiple
Inputs can be linked together and multiple outputs can be linked
together. Inputs and Outputs are linked separately.
3. Peak Level LED - Indicates the current peak level of the Signal:
Signal, -12dB, -6dB, -3dB, Over/Limit. The Input Over LED references to
the device's maximum headroom. The Output Limit LED references to
the threshold of the limiter.
4. Menu keys - There are 8 menu keys for Signal-Gain/Phase/Delay, EQ,
X’over (Crossover), Limiter, Channel (Input Mix), Name (Channel name) for
each input/output channel and System and Exit control for main system.

5. Rotary Thumb Wheel - Changes data values of a parameter and
confirms the change. The wheel has travel velocity sensing which eases
large incremental data modifications. While modifying delay and frequency
(1 Hz resolution), pressing the Speed key simultaneously will
increment/decrement the data value by 100X. To confirm the setting push
the wheel one time.
6. LCD – 4 line x 32 words to show all the information necessary to control
the unit.
7. Cursor control- 4 keys for Cursor control.

4.0 Rear Panel Functions
1.
Main Power - Connected via a standard IEC socket. A compatible power
cord is supplied with the unit. The voltage input is 90-240VAC, 50-60Hz.
2. Main Fuse - T2.5A-250V. Slow blow type.
3. Power switch - Controls power On/Off.
4. RS485 – Enables remote control of the device up to 1000M..
5. XLR input and outputs - Separate 3-pin XLR connectors are provided
for each audio input and output. The device's output stage employs the
balanced impedance topology. All I/O connectors have pin 1 as ground
(shield), pin 2 as + and pin 3 as -.

5.0 Powering Up the Device
• After powering up the unit, the following initialization screen is displayed
on the LCD:
• The initialization process takes about 8 seconds and during that period
the unit boots and displays the device model and firmware version.
• After the initialization process is finished the LSM displays its main screen:
• The screen shows the current program number and program name
assigned to the unit. If the 2 fields are empty, it means that no program
is assigned, the last data before previous power down is recalled instead.
• Now the LSM is ready to operate.
