DIGITAL SR AMPLIFIER
8 DSA-100D/DV
7. MODE SWITCH
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.
