కీ ఫీచర్లు
- Eight High-Quality Preamps: Features eight award-winning Focusrite microphone preampజీవితకారులు.
- Integrated Digital Output: Includes an eight-channel 24-bit / 96 kHz ADAT digital output for seamless integration with digital audio interfaces.
- Optimized for Drums: మైక్రోఫోన్ ప్రీamps are specifically optimized to handle high input levels, making them suitable for tracking drums.
- ఇన్స్ట్రుమెంట్ ఇన్పుట్లు: Two channels offer high-impedance (Hi-Z) instrument inputs, conveniently located on the front panel for direct connection of guitars and basses.
- ఇన్పుట్ మీటరింగ్: Each channel is equipped with fast-acting 5-LED input meters for clear visual reference of input levels, helping to prevent clipping.
- ఫాంటమ్ పవర్: 48V phantom power is available on every channel, switchable in two groups (1-4 and 5-8), for use with condenser microphones.
- అంతర్నిర్మిత కుదింపు: Features VCA-based, feed-forward compressors on each channel, derived from the Focusrite Red 3, with a single dial for control and a 'More' button for aggressive compression.
- Direct Outputs: Provides direct outputs on every channel for routing flexibility, particularly useful in live sound environments.
- అంతర్గత గడియారం: Delivers a jitter performance of less than 10 PPM, with a BNC connector for external clock synchronization using JetPLL jitter elimination technology.

The OctoPre MkII Dynamic offers various input and output options for integration into your audio setup.
Figure 2: Focusrite OctoPre MkII Dynamic Rear Panel.
This image shows the rear panel of the OctoPre MkII Dynamic, detailing the power input, Word Clock I/O, Optical ADAT outputs, Line Outputs, and Mic/Line Inputs.
- పవర్ కనెక్షన్: Connect the supplied AC power cable to the IEC inlet on the rear panel and to a suitable mains power outlet. Ensure the unit is properly earthed.
- Microphone/Line Inputs: Use XLR cables for microphone connections to inputs 1-8. For line-level signals, use 1/4-inch TRS or TS cables.
- Instrument Inputs (Channels 1 & 2): For instruments like guitars or basses, plug directly into the 1/4-inch DI inputs on the front panel. This bypasses the rear XLR input for these channels.
- ADAT Output: Connect the optical ADAT outputs (Lightpipe) to the ADAT input of your audio interface or digital mixer. The unit provides two mirrored ADAT outputs (44.1/48 kHz) for channels 1-8.
- లైన్ అవుట్పుట్లు: Use 1/4-inch TRS or TS cables to connect the individual line outputs (1-8) to an analog mixer or other analog recording equipment.
- పద గడియారం: For synchronization with external digital devices, connect a BNC cable from your master clock to the Word Clock input, or from the Word Clock output to slave devices.

ముందు ప్యానెల్ నియంత్రణలు
- Gain Knobs (1-8): Adjust the input gain for each microphone/line channel. Rotate clockwise to increase gain.
- Pad Buttons (1-8): Engages a 10dB pad for the corresponding channel, useful for very hot signals like close-miked drums.
- Phantom Power (48V) Switches: Two switches control 48V phantom power for channels 1-4 and 5-8. Press to engage for condenser microphones.
- Instrument Inputs (1 & 2): 1/4-inch jacks for direct connection of high-impedance instruments.
- Compressor Controls (1-8):
- Compress Knob: A single dial that simultaneously decreases the threshold and increases makeup gain for the VCA-based compressor.
- More Button: Engages a more aggressive compression mode, doubling the ratio from 2:1 to 4:1 and shifting the threshold range.
- Compress LED: Illuminates when compression is active.
- Input Meters (1-8): 5-LED ladders display the input level for each channel, indicating signal presence, nominal level, and potential clipping (O/L).
- Sample Rate Select: Buttons to select the desired sample rate (44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz) for the ADAT output.
- Sync Source Select: Buttons to choose the clock source: Internal, ADAT, or Word Clock.
- పవర్ బటన్: యూనిట్ని ఆన్ లేదా ఆఫ్ చేస్తుంది.
Using the Compressors
The OctoPre MkII Dynamic features a unique single-dial compressor on each channel. Turning the 'Compress' knob clockwise increases the amount of compression. For a more pronounced and aggressive compression effect, engage the 'More' button. The 'Compress' LED will light up when the compressor is actively reducing the signal's dynamic range.
సమకాలీకరణ
For stable digital audio, it is crucial to properly synchronize the OctoPre MkII Dynamic with your other digital devices. Select the desired sample rate using the 'Sample Rate' buttons. Then, choose your sync source: 'Internal' for the OctoPre's own clock, 'ADAT' if receiving clock from an ADAT input, or 'Word Clock' if synchronizing via the BNC Word Clock input.
