digipro SUB 15D Digital Power Subwoofer
DESCRIPTION
The “SUB D” series speakers are equipped with DIG I PRO® series class D amplifier. These high-efficiency amplifiers deliver high output power in a compact size and low weight. Thanks to its high efficiency, the cooling of the amplifier module is obtained statically, thus avoiding the use of a fan. The power supply circuit of the DIGIPRO® amplifier, assembled on SUB 15D speaker, has been designed to work according to power supply voltage and to the SMPS (SwitchedMode Power Supplies) technology. The power supply circuits of the DIG I PRO® amplifier, assembled on SUB 18D, has been designed to work in full- range mode; thanks to the SMPS (Switched-Mode Power Supplies) technology with PFC (Power Factor Correction) the operation with supply voltages between 100 Vac and 240Vac is guaranteed by ensuring the same sound performances even with floating and non-stabilized power supply systems. SUB D is a series of active subwoofers made of birch wood, designed for medium to large size rooms. The subwoofer speaker is made using “BAND PASS” so that high sound pressures can be achieved in compact dimensions. For easy use, installation and transport, all subwoofers are provided with:
- handles on sides
- standard (M20) pole mount plate
- top part of the box features recesses for making it easier to superimpose the FLEXSYS series tops or another subwoofer.
- wheels predisposition (only SUB 18D)
The speakers are active sub-woofers designed to function in stereo and in mono
modes. It is possible to set crossover frequency (90Hz or 120Hz) and turning
of phase (0° or 180°).
The output signals can be linked or controller by X-OVER output.
CHARACTERISTICS
Cooling
The amplifier is cooled by means of the aluminium panel placed on the back of
the speaker.
The thermal protection is ensured by an internal circuit which controls the
temperature of the amplifier and protects this against any risk of overheating
thus limiting the general volume (temperature > 70°C).
If the temperature reaches the maximum operating temperature (>80°C), the
audio signal is set to the “MUTE” position and it will be indicated by the
switching on of the yellow “MUTE” LED.
The requiriered volume and all functions will be restored automatically when
the normal operating temperatures are reached.
Protection
When the yellow “MUTE” LED turns on, it means that a malfunction has been
detected on the speaker, thus setting this to the mute position.
Perform the checks listed below:
- Check if the speaker is properly connected to the power supply.
- Make sure that the power supply is of correct voltage.
- Check that the amplifier is not overheated.
- Disconnect the speaker from the mains power supply, wait for a few minutes and connect it again.
If after these tests the yellow “MUTE” LED is still on, please contact an authorised service center.
CONNECTIONS
Connecting to the mains supply
Each active speaker features its own power cable. Connection is done by a
Neutrik POWER CON® (blue) model which permits easy and fast connection to the
speaker as well as being an excellent locking system.
The same connector serves as a switch to turn ON and OFF the active
loudspeaker by turning the connector to the left (OFF) or right (ON).
The active speaker must be connected to a power supply able to deliver the
maximum required power.
Main power supply linking
On the rear of the speaker, a Neutrik POWER CON® connector (grey) offers
linking the mains power supply.
This socket links the power supply to another speaker, thereby reducing the
direct connections to the mains. Maximum amplifier input power is shown on the
amplifier panel. The maximum number of speakers connected together varies of
max input power and of the maximum allowed current of the first power socket.
LOUDSPEAKER INSTALLATION
WARNING
Make sure that the loudspeaker is securely installed in a stable position to
avoid any injuries or damages to persons or property.
For safety reasons do not place one loudspeaker on top of another without
proper fastening systems.
If you use the loudspeakers outdoors avoid places that are exposed to bad
weather.
The loudspeaker is supplied by the manufacturer company for use in support
WARNING
Never use the handles to hang the speaker!
CONTROLS AND FUNCTIONS
-
“BALANCED INPUT 1 “AND ” BALANCED INPUT 2″INPUT CONNECTORS Balanced inputs at line level. Accept “XLR” sockets.
-
“OUT 1 “AND “OUT 2” OUTPUT CONNECTORS
The “XLR” connectors be used to send the input audio signal to another amplified speaker.
The signal is choosing between “LINK/XOVER” (10) switch. -
“LIMITER” INDICATOR LIGHT
Th is indicator shows red to indicate that the internal Ii miter circuit has tripped.
This prevents amplifier distortion and protects the speakers against overloads. -
“SIGNAL” INDICATOR LIGHT
This indicator shows green to indicate the presence of the audio signal (at a level of- 20dB). -
“MUTE” INDICATOR LIGHT
This yellow indicator indicates amplifier status.
The LED is off in normal operating conditions. -
“READY” INDICATOR LIGHT
This indicator shows green to indicate that the main power voltage is correct.
The LED shows green normal operating conditions -
“INPUT SENS” INPUT SENSITIVITY CONTROL
This control adjusts the sensitivity of the signal amplifier input.
This control does not affect the “OUT 1 “and “OUT 2 “outputs levels -
“PHASE” SWITCH
This two-position switch permits turning the audio signal reproduced by the subwoofer by 180°.
Rotation makes it easier to optimise the reproduction of the low frequencies even in the most difficult installation situations. After completing installation, play a piece of music and move the switch to achieve the best sound reproduction at low frequencies. -
“XOVER” SWITCH
This switch permits selecting the crossover frequency between the subwoofer and the speakers connected to the “OUT 1 “and “OUT 2 “outputs. Choice depends on the type of speaker used for reproduction of mid-high frequencies.
For speakers with 12″ cones, it is best to use 120Hz, while with 15” speakers 90Hz. -
“LINK/XOVER” SWITCH
This switch allows to select the signal type to send “OUT 1 “and “OUT 2 “outputs. The “LINK” position allows to link the same input signal.
The “XOVER” position allows to send input signal according to crossover frequency select by XOVER (9) switch. -
“MAINS INPUT” POWER SOCKET
For connecting the power cable provided.
The connector used for mains connection is a POWER CON® (blue) socket -
“MAINS OUTPUT LINK” POWER SOCKET
For linking the mains power. The output is connected in parallel with input (11) and can be used to power another active speaker.
The connector is a POWER CON® (grey) socket -
“MAINS FUSE” FUSE CARRIER
Mains fuse housing.
