Features
Features
- Compact Design
The DSA Series is a amplifier 100 watts x 2 of Power that is housed in half rack 1 RU compact chassis. Ideal
for applications where high power stereo amplification is required such as board room and class rooms.
- Professional Grade D-Class Amplifier and Switch Mode Power Supply (SMPS)
Class D amplifier offer improved total harmonic distortion with an increased signal to noise ratio of
professional grade sound quality. SMPS creates a high efficiency amplifier offering reduced power
consumption and low heat dissipation.
- APD (Auto Power Down)
The amplifiers automatically enter into a standby mode after 30 min when unit is not in active, it takes a
advantage of reducing power consumption.
The unit returns to operating status within 3 sec upon signal detection.
- ENERGY STAR - Low Power Compsumtion in STAND BY mode
In STAND BY mode, the unit only takes a less than 1W of electric power compsumtion which complies
with ENERGY STAR® standards.
- GAIN selection switch
Selectable proper input sensitivity of amplifier either +4dBu (1.2283V) or -20dBu (77.5mV)
- High Pass Filter (120Hz)
Built in High Pass Filter to protect the speaker against unwanted low frequency.
- Bridge-Mono Mode
Bridging allows power to be output at 200 watts.
- Power Mode Selection Switch
There are 3 selectable power mode switch (ON/REMOTE/OFF). When switch is selected as REMOTE, the
amplifiers can be remotely power ON/OFF control.
- Remote Power Connector
The remote power allows the amplifier to be turned on or off from a distance or other device via dry contact
closure.
- Front siganl and protection LED indicators
LED indicators for POWER, STAND BY, PROTECTION, SIGNAL and CLIP on the front panel give a easy
verification of operation status.
- Advanced Protection Circuitry
Advanced protection circuitry guards against overheating, shorted outputs, DC output, overloads.
- Balanced Input
This connection is used to ensure the lowest noise operation which eliminates the common noise from the cable.
- VCA (Voltage Control Amplifier) Control (Only DSA-100DV)
Voltage-controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage. These
two terminals provide connection for an external potentiometer. When the potentiometer is connected, it allows
for remote control of the master volume level.
Note that individual input volume control positions limit the maximum output level adjustable with the remote
volume control.

1. VOLUME CONTROL
Turn the volume controls clockwise to increase gain and counterclockwise to decrease gain against each
channel.
2. OUTPUT SIGNAL LEVEL INDICATORS
The LEDS indicate the amplifier’s output signal levels.
- SIGNAL LED Illuminates green when signal is present at the input more then -25dB.
- CLIP LED illuminates red when there are excessive signal levels.
※ NOTE : The Cliping may damage the speakers and amplifier so when CLIP LED is on please lower the
volume level.
3. PROTECTION MODE INDICATOR
The amplifier features several types of protection circuitry to prevent damage during power-up or fault
conditions such as overheat, overload and a detection of DC output. PROTECTION LED illuminates when
any of these faults is detected. The output relays will disconnect the speaker loads when the protection
circuitry detects a fault condition. Once the specific fault has been corrected, the PROTECTION LED will be
turned off and The unit will be working normally.
Protect LEDs will illuminate for 2 to 3 sec during power-up process then after 2 to 3 sec PROTECTION LED
will be turned off and stay as normal condition to use.
4. COOLING VENTS
Air flow is front to back. DO NOT block front or rear air vents.

5. POWER LED INDICATOR
- POWER LED illuminates green when the rear power selection switch is selected as ON or the remote power
contact is triggered when the rear power selection switch is selected as REMOTE.
The unit turns into APD (Auto Power Down) mode, the power LED will turns off.
- STAND BY LED illuminates yellow when the rear power selection switch is selected as OFF or the remote
power contact is not triggered when the rear power selection switch is selected as REMOTE.
● APD (Auto Power Down) function
①
when the rear power selection switch is selected as ON or
②
when the rear power selection switch is selected as REMOTE and the remote power contact is not triggered,
it will activate the APD mode.
- POWER LED illuminates green until APD mode is on under that circumstance.
- The amplifiers automatically enter into a standby mode after 30 min of inactivity then STANBY LED will
illuminates yellow which helps to minimumize the electric power consumption.
- The unit returns to operating status within 3 sec upon signal over -30dB detection, STAND BYE LED will be
off and POWER LED will illuminates green.

※ NOTE : Before connecting speakers to the unit, be sure to disconnect the AC power cable. Make certain
that the total impedance is not less than the rated impedance indicated.
Do not put the speaker cable close to input signal cable.
4. VCA (VOLTAGE CONTROLLED AMPLIFIER) TERMINAL (Only DSA-100DV)
When the potentiometer is connected, it allows for remote control of the master volume level.
CH1 remote volume : connect into "V1, C1, G" with 10kΩ volume (B curve type)
CH2 remote volume : connect into "V2, C2, G" with 10kΩ volume (B curve type)
Connections of VCA control terminal. (see below picture)
* VCA (VOLTAGE CONTROL AMPLIFIER)
Voltage-controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage.
These two terminals provide connection for an external potentiometer. When the potentiometer is
connected, it allows for remote control of the master volume level without sound distortion.
※ NOTE : Note that individual input volume control positions limit the maximum output level adjustable with
the remote volume control
If VCA control unit is seperated from the unit, it goes back to level of front panel volume control
so do not separate the VCA control unit while it is in use.
5. POWER MODE SELECTION SWITCH
- There are 3 selectable power mode switch. (ON/REMOTE/OFF)
- Switches to ON : Power ON

. MODE SWITCH
7
Mode selection switch for either CH1/CH2 stereo or BRIDGE mono mode
(1) CH1/CH2 MODE
Input signal of each channel will drive each channel independently. Input signal of CH1 drives Amp
output of CH1, Input signal of CH2 drives Amp output of CH2. In this case volume can be controlled
independently on both channel.
(2) BRIDGE MODE
The bridge mono mode combines both channels to create one larger mono channel.
By connecting CH1 (+) terminal and CH2 (-) terminal, The amplifier will deliver approximately twice the
voltage at CH1. Please observe the minimum load specification when operating in Bridge mode.
※ NOTE : In BRIDGE mode, Do not use the CH2 input because only CH1 input is active and put the CH2
volume control to minimum position which only volume will controlled by CH1 volume control.
In BRIDGE mode the speaker impedance load must be atleast 8Ω.
※ NOTE : When connected to the OPT-100D, set the mode switch to "2CH".
(The OPT-100D DO NOT support the bridged mode.)
8. HIGH PASS FILTER SWITCH (ON/OFF)
Select swich position to ON, it will activate 120Hz -12dB / OCT High Pass Filter.
※ NOTE : When connected to the OPT-100D, set the HPF switch to "ON".
※ NOTE : High Pass Filter is to increase sound clarity and improve output sound.
9. GAIN SELECTION SWITCH
Select proper input sensitivity of amplifier either +4dBu (1.2283V) or -20dBu (77.5mV)
※ NOTE : The -20dBu is designed for low level device of audio source. If you connect the a general audio
device (such as CD, TUNER, DECK ect) and set up the -20dBu together, the quality of sound may
be deteriorated.
10. INPUT TERMINAL
These inputs are balanced and configured as follows: + (signal plus), - (signal minus), GND (ground)
※ NOTE : Connect or disconnect input terminal after unpluging the power cord.
