2. સલામતી માહિતી
To prevent electric shock, fire, or damage to the unit, please observe the following precautions:
- પાવર સપ્લાય: ફક્ત ઉલ્લેખિત પાવર એડેપ્ટરનો ઉપયોગ કરો. ખાતરી કરો કે વોલ્યુમtage તમારા પ્રદેશની જરૂરિયાતો સાથે મેળ ખાય છે.
- ભેજ: Do not expose the unit to rain, moisture, or excessive humidity. Do not place containers with liquids on the unit.
- વેન્ટિલેશન: યુનિટની આસપાસ પૂરતું વેન્ટિલેશન સુનિશ્ચિત કરો. વેન્ટિલેશનના છિદ્રોને અવરોધશો નહીં.
- ઉષ્મા: રેડિએટર્સ, હીટ રજિસ્ટર, સ્ટોવ અથવા ગરમી ઉત્પન્ન કરતા અન્ય ઉપકરણો જેવા ગરમીના સ્ત્રોતોથી યુનિટને દૂર રાખો.
- સફાઈ: સફાઈ કરતા પહેલા પાવર ડિસ્કનેક્ટ કરો. સૂકા, નરમ કપડાનો ઉપયોગ કરો. પ્રવાહી ક્લીનર્સ અથવા એરોસોલ ક્લીનર્સનો ઉપયોગ કરશો નહીં.
- સર્વિસિંગ: યુનિટની જાતે સર્વિસ કરવાનો પ્રયાસ કરશો નહીં. બધી સર્વિસિંગ લાયકાત ધરાવતા સેવા કર્મચારીઓને સોંપો.

5. સેટઅપ
5.1 અનપેકિંગ અને પ્લેસમેન્ટ
Carefully remove the OB-6 from its packaging. Place the synthesizer on a stable, flat surface, ensuring sufficient space for ventilation around the unit.
5.2 પાવર કનેક્શન
- Ensure the OB-6 power switch is in the OFF position.
- Connect the provided power supply to the power input on the rear panel of the OB-6.
- Plug the power supply into a suitable AC outlet.
5.3 ઓડિયો કનેક્શન્સ
Connect the main audio outputs (Right/Mono, Left) on the rear panel to your mixer, audio interface, or amplifier using standard 1/4-inch TS cables. For stereo operation, connect both Left and Right outputs. For mono, use the Left/Mono output.
૨.૩ MIDI અને USB કનેક્શન્સ
The OB-6 supports both traditional MIDI (DIN connectors) and USB MIDI for communication with computers or other MIDI devices.
- MIDI: Connect MIDI OUT of your controller/interface to MIDI IN of the OB-6. Connect MIDI OUT of the OB-6 to MIDI IN of your other devices or interface.
- યુએસબી: Connect a USB Type A cable from the OB-6's USB port to a USB port on your computer. The OB-6 will appear as a MIDI device in your operating system and DAW.

6.1 પાવરિંગ ચાલુ/બંધ
To power on the OB-6, flip the power switch on the rear panel to the ON position. The display will illuminate, and the synthesizer will initialize. To power off, flip the switch back to the OFF position. Always power off the unit before disconnecting the power supply.
૪.૧ મૂળભૂત ધ્વનિ નિર્માણ
The OB-6's sound engine is based on two voltage-controlled oscillators (VCOs) per voice, a sub-oscillator, a noise generator, a mixer, a state-variable filter, and two envelopes (filter and ampજીવંત).
- ઓસિલેટર: Use the OSCILLATORS section to select waveform (saw, pulse), adjust frequency, and fine-tune.
- મિક્સર: The MIXER section blends the levels of OSC 1, OSC 2, Sub, and Noise.
- ફિલ્ટર: The FILTER section controls the cutoff frequency, resonance, and envelope amount. The OB-6 features a 2-pole, state-variable filter with low-pass, high-pass, band-pass, and notch modes.
- પરબિડીયાઓ: The FILTER ENVELOPE and LOUDNESS ENVELOPE sections control the attack, decay, sustain, and release stages for dynamic sound shaping.
6.3 Program Management
The OB-6 stores a large number of factory and user programs (presets). Use the BANK and PROGRAM buttons to navigate and select programs. To save a modified program, press the WRITE button, select a destination, and press WRITE again to confirm.
