DCA 1
is a very versatile amplifier that can operate in many different ways, making it suitable for facilities in restaurants,
small shops, etc.
DCA 1
features an amplification system with 120W + 120W and 8 mono input sources, that depending on the
configuration, can become in 8 inputs. One of them has MIC connection in stacking for priority functions and
phantom power. Using DMX, you can select the input source and control the volume.
DCA 1
also incorporates RS232 and RS485 communication ports for ASCII control commands.
1. LED indicators -
These LEDs indicate the output state of the device.
- SIGNAL LEDs
(green colour) indicate the presence of signal in the correspond input amplifier.
- CLIP LEDs
(red colour) they indicate a clip state with high level peaks of signal. The ideal working mode of these
LEDs is flicking, if the LEDs are litting, reduce the input signal in order to protect the amplifier and the loudspeakers.
- PROT LED
(red colour) they indicate the amplifier protection state against, output short circuits, DC or overheating.
2. LCD Display
- This 2x16 characters alphanumeric LCD displays show the current state and the setup information with
the different configurable parameters using the encoder (3).
3. ENCODER
- This encoder allows to navigate through configuration parameters, selecting it and changing its properties.
