Abstract
Audio merupakan suara atau bunyi yang dihasilkan oleh getaran suatu benda, agar dapat tertangkap oleh telinga manusia, getaran tersebut harus kuat minimal 20 kali/detik. Sedangkan panggung merupakan tempat dimana biasanya terdapat audio dan pengaturan audio. Audio panggung yang ada saat ini banyak mengunakan kabel untuk menyambungkan antara loadspeaker ke pengaturan audio. Letak pengaturan audio dan panggung biasanya memiliki jarak yang cukup jauh. Sehingga membutuhkan banyak kabel, dan juga biasanya banyak kabel berserakan di atas panggung sehingga bisa mengganggu kegiataan diatas panggung.
Salah satu solusi alternatif yaitu dengan menggunakan perangkat keras transmisi dan kendali volume audio panggung tanpa kabel yang mampu mengurangi kabel dalam sistem audio. Alat ini dilengkapi dengan pemancar radio frekuensi, rangkaian DAC, rangkaian VCA, rangkaian mini amplifier dalam pengoperasiannya. Pengaturan volume dan pengiriman sinyal audio dilakukan secara wireless.
Dari hasil pengujian yang telah dilakukan, didapat bahwa pemancar radio frekuensi bisa memancarkan frekuensi dan bisa diterima dengan modul radio dengan jarak kurang lebih 7 meter. Pengaturan volume menggunakan HP Android mampu bekerja dengan jarak 70 meter. Rangkaian DAC dan rangkaian VCA mampu bekerja sesuai dengan pengaturan yang terdapat pada HP Android. Rangkaian mini amplifier mampu mengeluarkan suara sesuai dengan perintah HP Android. Pengaturan volume dikendalikan oleh HP Android yang terkoneksi dengan Bluetooth yang tersambung pada Arduino.

Audio is a sound or a sound that is produced by the vibration of an object, so that they can be caught by the human ear, vibration must be strong at least 20 times/seconds. While the stage is a place where there is typically audio and audio settings . Audio current stage many are using the cable to connect between the loadspeaker to the audio settings. Audio setting layout and the stage is usually have the distance far enough. So that requires a lot of cable, and also usually many scattered cable on stage so that can interfere with the activities above the stage.
One of the alternative solution is to use the hardware transmission and audio volume control the stage without the cable that is able to reduce the cable in the audio system. This appliance is equipped with a radio transmitter frequency, series DAC, series VCA, a series of mini amplifier in operation. Volume settings and delivery of the audio signal is done by wireless.
From the results of the testing that has been done in the can that a radio transmitter frequency can transmit frequency and can be received with the radio module with a distance of approximately 7 meters. Volume settings using HP Android capable of working with a distance of 70 meters. A series of DAC and a series of VCA are able to work in accordance with the settings that are located on the HP Android. A series of mini amplifier is able to produce the sound in accordance with the command of the HP Android. The volume setting is controlled by the HP Android connected with Bluetooth connected on Arduino.
