CHEK FHASE AUDIO

Check Phase schema

Pernahkan sobat mengalami pasang sterio system 1speaker bagus tambah 1 malah apang?
itu berarti salah satu speaker ada yang out phase(terbalik min plusnya)n kalo kasus seperti
itu masih bisa diatasi hanya membalik salah satu kabel saja sudah jadi,,walaupun posisi phase
di in phase atau out phase,yang benar di in phase,,lampu indikator nyala hijau pada alat.
Coba bayangkan kalo kita pasang speaker 5 saja kiri 5 kanan 5 sulit sekali kita mendeteksi
phasenya.

Saya akan menerangkan sedikit tentan cek phase,cek phase biasanya ada 2 item yaitu reciver gunanya untuk memonitoring hasil phase yang dihasilkan dari suara elektonik maupun acoustic.
Sedangankan transmiter adalah generator yang menghasilkan gelombang kotak yang di
masukan ke perangkat audio yang di teruskan ke loudspeaker.
Alat tersebut sudah populer di dunia engineering audio..(operator) tapi kalo sobat belum meamkai alat tersebut saya anjurkan harus beli.
Kenapa harus punya???alat tersebut vital sekali selagi sobat mempunyai banyak speaker
yang terpasanng ketika kita dapat job ngeson,nggak mungkin kita cek box demi box nengan telinga apakah phasenya dah betul ato belum.
Harga cek phase yang brandit cukup tidak terjangkau
Bulan depan saya ingin bagikan skema cek phase secara gratis...

Catatan: beda power biasanya beda phase
:beda sumber listrik biasanya beda phase
:tambah acesoris juga di cek phase ulang
:pemasangan cek phase setelah complit terpasang
:di line mixer audio

Cara pasang: tranmiter dimasukan mixer pada lin in,posisi tone flat.
:reciver di todongkan depan speaker pas tengah persis

Sekian..kalo ada susuna kalimat kurang bagus mohon maaf, salam...Skema cek phase

Bulan yang lalu saya sudah bahas tentang Cek Phase dan kali ini saya unggah skema Cek Phase yang
pernah saya janjikan,,dengan skema sederhana ini smoga bisa bermamfaat dan setidaknya untuk
wawasan

GAMBAR YANG SUDAH JADI DENGAN PCB LUBANG

Ic Cek Phase,bulan lalu sudah saya terangkan,penggunaan Cek Phase dan skemanya juga sudah saya unggah
kali ini saya berikan Type ic-nya.Sudah tau caranya sudah ada skemanya kok belum ada type-nya..lucu kan?
Mohon maaf pada rekan2 yang sudah mengikuti blog saya,,dan jangan lupa slalu kunjungi ya..kalau ada ilmu
baru pasti saya bagikan.
Typetype ic cek phase
IC.1-CD 4049

IC.2-CD 4093

IC.3-HEF 4027

catatan:pada zener dioda 5v.sedangakan type pembangkit pulse-nya CD 4093
Usahakan pada type HEF 4027 merk philip agar sempurna. IC

Parametrik Tone Control

Middle Frequency Equalizer with Parametric Feature

Posted Jan 17, 2012 at 9:14 am

Figure 1 

The circuit was designed to produce an equalizer that would cater the middle frequency signals with limited and parametric attribute.

• Equalizer – a passive or an active electronic element or circuits (like tone control) used for the reason of altering or flattening the frequency response characteristics of a system
• NE5532 – an internally compensated low noise dual operational amplifier with features such as full power bandwidth up to 140 KHz, input noise voltage of 8 nV, common mode rejection ratio, 9 V/us slew rate, high DC voltage gain, 32 V peak to peak voltage swing, wide supply voltage range from 3 V to 12 V, unity gain bandwidth at 10 MHz, and internal frequency compensation

The circuit can be used with any other audio circuit although it is normally connected to the microphone line balance unit. The circuit is comprised of two parts having a typical bass and treble circuit and a parametric circuit of mid frequencies. The circuit of the equalizer will take an audio output, and manually boosting or attenuating the amplitude by adjusting the two channels consisting of the bass with 20 HZ to 1 KHz and the treble with 1 KHz to 20 KHz. With 18 dB at 20 KHz, the high frequencies are regulated by R2 while the low frequencies are regulated by R5. At 15 dB, the middle frequency is regulated by R11 while the center of middle frequency at 200 Hz to 6 KHz is regulated by R10.
The level of the bass is controlled below a certain frequency while treble changes are made above a certain frequency. The equalization of mid frequency rises to a maximum at its center frequency which will quickly fall off again to a flat response while passing all frequencies. Nevertheless, the output of the equalizer circuit provides sufficient amplification to a speaker.

Figure 2 

One of the handiest audio tools for videography is the use of the equalizer to eliminate problems in some soundtracks. They can be located in a rack full of audio processors or in an audio mixer. They are used to assist in the elimination of unwanted noise, capture a horrible audio buzz, to control the audio tonal balance, and decrease the tape hiss. This type of equalizer circuit is commonly used in stereo receivers and small audio mixers.
