1.INTRODUCTION
The DSP306/408 USB is a complete digital loudspeaker management system
designed for the touring or fixed sound installation markets. The absolute latest in
available technology is utilized with 40-bit floating point processors and high
performance 24-bit Analogue 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, 8 bands of
parametric EQ per channel, 31 bands of graphic EQ per input, 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
requirements.
The DSP306/408 USB can be controlled or configured in real time on the front panel
or with the intuitive PC GUI accessed via the USB interface (or optionally Ethernet).
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.THE FRONT PANEL
A) USB Connector – A standard type B USB connector for interface with a PC.
Software and driver must be installed prior to usage.
B) Mute keys - Mute/Unmute input and output channels. When an input channel is
muted, they key will light up in red for indication.
The Mute keys are also used to access the program of each channel in combination
with the Menu> and <Menu keys. Holding one of the Menu keys and pressing the
Mute key of the desired channel will give access to the channel parameters, and will
be acknowledged by a green led below the mute key. Multiple channels can be linked
or unlinked to ease the programming. Inputs and outputs are linked separately.
C) Channel Menu LED – Indicates the activated channels for parameter modification
D) Peak Level LED - Indicates the current peak level of the Signal: Signal, -12dB, -
6dB, -3dB, Overload/Limit. The Input Overload LED references to the device's
maximum headroom. The Output Limit LED references to the threshold of the
limiter.
E) LCD - Shows all the necessary information to control the unit.
F) Menu Control keys - There are 6 menu keys: <Menu (Menu Down), Menu>
(Menu Up), <Select (Cursor Down), Select> (Cursor Up), Enter and Exit. The
functions of each key is explained below:
<Menu: Previous menu screen. In combination with the channel Mute key, the
specific channel Menu is displayed.
Menu>: Next menu screen. In combination with the channel Mute key, the specific
channel Menu is displayed.
<Select: Previous cursor in the menu screen
Select>: Next cursor in the menu screen

Enter: This key has three different functions depending on when it is used:
- In the System Menu is used to proceed with selected actions.
- In the Main Menu allows entering the System Menu.
- In delay and frequency adjustments (1 Hz resolution mode) modifies data values by
100X (used with thumb wheel).
Exit: Exit to the Main Menu
G) Rotary Thumb Wheel - Changes parameter data values. The wheel has travel
velocity sensing which ease large incremental data modifications. For modifying
delay and frequency (1 Hz resolution), pressing the Enter key simultaneously will
increment/decrement the data value by 100X.

4.THE REAR PANEL
A) Power switch - Controls power On/Off.
B) Main Fuse - T200mA-250V. Slow blow type.
C) Main Power - Connects via a standard IEC socket. A compatible power cord is
supplied with the unit. The voltage input is 90-240VAC, 50-60Hz
D) Ethernet slot – Slot to install the optional Ethernet module. With this accessory,
the unit can be connected to a router, switch or PC through CAT-5 cable.
E) 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.POWER UP
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 DSP306 or DSP408 firmware version.
After that, the DSP unit displays its main screen:
The screen shows the current program number and program name assigned to the
unit. The program assigned is always the last program the user recalled or stored
before powering down the unit. An asterisk (*) beside the program number means
that the program has been modified but not stored.
Now the DSP unit is ready to operate.

6.OPERATING THE DEVICE
6.1.Input Menus
To access the Input Menus, hold the <Menu or Menu> key and press the Mute key of
the desired channel. The green led below the Mute key will light up. More than one
input channel may be selected by holding the Menu key and pressing the
corresponding Mute key. Press Exit to deselect all.
The following menus are available for each input channel:
6.1.1. Signal - Signal parameters
• LEVEL - Gain, -40.00dB to +15.00dB in 0.25dB steps.
• POL - Polarity, can be normal (+) or inverted (-).
• DELAY - Delay in 11us steps. It can be displayed in ms, ft or m. The time unit of the
delay can be changed in the System menu. The maximum delay permitted is 650ms.
6.1.2.EQ - EQ parameters
• EQ# - Selects one of the 8 available Equalizers.
• BYPASS – When set On, the currently selected EQ will be bypassed.
LEVEL:0.00dB
