Which pins go to which on the arduino board.** A: A lot of it depends on how you've written your program, because that's where you specify certain pins. If I remember correctly, you will want to specify that the "out" (on the microphone) goes to one of the Analog-to-Digital (ADC) pins--on an UNO, that's A0 through A5 (you'll specify that in your code). You'll want either the 5V or 3V3 on the Uno to connect to VCC on the mic; GND on the mic to one of the ground pins on the Uno. The "gain" pin on the mic depends on how much gain you want; if you don't connect it, you'll get 60dB of gain; connect it to GND on the mic for 50dB, and connect it to VCC on the mic for 40dB. I recommend you check the results of each to see which one works best for your needs--high gain will pick up every little noise & detail in music, whereas less gain will make the differences between loud & quiet sounds more obvious; it's basically equivalent to 'normalization' in music. Finally, the AR pin is for the "Attack/Release" ratio, which defaults to 1/4000; this basically determines how quick the mic is to 'react' to sounds, and the default is the most 'reactive' setting. If you want to make it a less so, connect it to either the VCC pin or GND for different settings; odds are good that you'll be happier with the original.

How do i wire it for another amplifier stage?** A: If your p.a. amp has a mic input, I don't think you will need any more amplification. The AGC has a very wide range. **Q: I need to feed the output into a 1w 8 ohm speaker. Will this work for that ?** A: You will probably need a 1 watt audio amp to drive the speaker. **Q: Since this mic has auto gain, does that mean it wouldn't be useful for determining sound levels?** A: You can hard-set the gain by wiring the pin to V++ or ground ## Frequently Bought Together - Adafruit Electret Microphone Amplifier - MAX9814 with Auto Gain Control [ADA1713] - Arduino UNO R4 WiFi [ABX00087] - Renesas RA4M1 / ESP32-S3 - Wi-Fi, Bluetooth, USB-C, CAN, DAC, OP AMP, Qwiic Connector, 12x8 LED Matrix - DZS Elec 15PCS 35mm Piezo Disc Transducer Contact Microphone Trigger Sound Sensor with 4 Inches Wires for Acoustic Instrument --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/19454212-adafruit-electret-microphone-amplifier-max9814-with-auto-gain-control-ada1713](https://www.desertcart.ph/products/19454212-adafruit-electret-microphone-amplifier-max9814-with-auto-gain-control-ada1713) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-11*
