Focusrite ISA Two Dual Mono Microphone Preamplifier Колдонмо

Продукт бүттүview

The Focusrite ISA Two is a classic dual mono transformer-based microphone preamplifier designed for professional audio recording. It incorporates the renowned Lundahl LL1538 mic input transformer, originally selected by Rupert Neve for the ISA 110, ensuring exceptional audio quality.

Негизги өзгөчөлүктөр төмөнкүлөрдү камтыйт:

• Lundahl LL1538 Transformer: Utilizes the high-quality Lundahl LL1538 mic input transformer for superior sound.
• High Gain and Low Noise: Offers up to 80 dB of clean gain on the microphone input with minimal noise.
• Өзгөрмө киргизүү импедансы: Four selectable input impedance settings, including the original ISA 110 value, allow for optimal matching with various microphones.
• User-Calibrated Metering: Each channel features an eight-LED array for clear level display, with a rear panel calibration knob to match DAW converters.
• Ар тараптуу киргизүүлөр: Two 1/4-inch front panel DI inputs for instruments and rear panel TRS line inputs.
• Жогорку өткөрүүчү чыпка: An 18dB/octave high-pass filter, based on the ISA 110 module, is built-in for precise low-frequency control.
• Balanced Inserts: Each channel includes balanced insert points (1/4-inch TRS send and receive) for integrating external hardware processors.

Орнотуу колдонмосу

Follow these steps to set up your ISA Two preampөмүр берүүчү:

1. Rackmount орнотуу: The ISA Two is designed for standard 19-inch rack mounting. Secure the unit using appropriate rack screws.
2. Кубат туташуу: Connect the supplied IEC power cable to the rear panel power inlet and then to a suitable AC power source. Ensure the power switch is in the OFF position before connecting.
3. Микрофондорду туташтыруу: Use balanced XLR cables to connect your microphones to the 'MIC INPUT' XLR connectors on the rear panel for each channel.
4. Connecting Line Sources: For line-level signals, use balanced TRS cables to connect to the 'LINE INPUT' TRS connectors on the rear panel.
5. Туташтыруучу аспаптар: For instruments such as guitars or basses, use 1/4-inch jack cables to connect to the 'Instrument Inputs' on the front panel.
6. Чыгуу туташуулары: Connect the 'OUTPUT' XLR connectors on the rear panel to your audio interface, mixer, or other recording equipment using balanced XLR cables.
7. Insert Connections: If using external hardware processors, connect them to the 'SEND' and 'RETURN' 1/4-inch TRS jacks on the rear panel for each channel.

Иштөө нускамалары

This section details the operation of the ISA Two preamplifier's controls:

1. Күйгүзүү: After all connections are made, switch the power button on the front panel to the ON position.
2. Киргизүүнү тандоо: Use the 'Input' buttons (Mic, Line, Inst) to select the appropriate input source for each channel. Ensure only one input type is active per channel.
3. Көзөмөлдү алуу: The large 'Gain' knob adjusts the primary gain level (e.g., 0-30 dB, 30-60 dB). The smaller 'Trim' knob provides fine-tuning (+/-10 dB) for precise level setting.
4. Variable Input Impedance (Z In): For microphone inputs, select one of the four impedance settings (Low, ISA 110, Med, High) to optimize the interaction with your microphone. Experiment to find the best sonic match.
5. Phantom Power (+48V): Activate the +48V button for condenser microphones that require phantom power. Ensure the microphone is connected before engaging phantom power.
6. Жогорку өтүүчү чыпка (HPF): Engage the 'Filter' button and use the 'High Pass Filter' knob to remove unwanted low-frequency rumble or proximity effect. The filter offers an 18dB/octave slope.
7. Insert Function: Press the 'Insert' button to engage any external hardware processors connected to the rear panel insert points.
8. Ченөө: Monitor your signal levels using the eight-LED array. Adjust gain and trim to achieve optimal levels without clipping (red LEDs). The VU meter provides an average level indication.

Техникалык тейлөө

To ensure the longevity and optimal performance of your Focusrite ISA Two, follow these maintenance guidelines:

• Тазалоо: Түзмөктүн сыртын тазалоо үчүн жумшак, кургак чүпүрөктү колдонуңуз. Абразивдүү тазалоочу каражаттарды, эриткичтерди же момдорду колдонбоңуз.
• Вентиляция: Ensure adequate airflow around the unit, especially if rackmounted, to prevent overheating.
• Сактагыч: When not in use for extended periods, store the unit in a cool, dry environment away from direct sunlight and extreme temperatures.
• Кабелдик башкаруу: Keep cables organized and free from kinks or excessive tension to prevent damage to connectors and the unit.

Проблемаларды чечүү

If you encounter issues with your ISA Two, consider the following common troubleshooting steps:

• Кубат жок: Check the power cable connection to both the unit and the wall outlet. Ensure the power switch is ON.
• Аудио чыгышы жок: Verify all input and output cables are securely connected. Check the input selection (Mic, Line, Inst) and ensure phantom power is engaged if using a condenser microphone. Confirm gain levels are appropriately set.
• Бурмаланган аудио: Reduce the input gain and trim levels. Check for proper impedance matching with your microphone. Ensure no cables are damaged.
• Үзүлгүс сигнал: Inspect all cable connections for looseness or damage. Try swapping cables to isolate a faulty one.
• Ызы-чуу/Гүлдөө: Ensure all equipment is properly grounded. Check for nearby sources of electromagnetic interference.
