Tapi watt besar nyer resistor ne mahal ooo. boleh sampai rm30 - rm50 sebijik... bukan 2 3 sen cam resistor biasa..

Yaaa, simple jer.
Tapi, dari pengalaman gua buat attenuator bukan semua resistor boleh pakai. kengkadang akan kuar noise.
Berapa watt amp nak pakai?
- utk amp watt kecik biasanya senang nak carik part.
- utk amp watt besar, kena carik resistor watt besar dan boleh tahan susah juga la. Ada jumpa nanti pun belom tentu ada value yg sesuai.
Nak pakai utk apa dummy load tu boss? boleh terang sikit.
Aku boleh buatkan sebab it simple circuit tapi aku tak jamin bebenda in utk kesihatan amp tu.
Aku sekarang pun memang tengah study bebenda attenuator, the design dan part nak pakai. YA memang kesukarannya adalah memilih part yg sesuai walopun melibatkan resistor jer. Sebab tu balo pun circuit attenuator ne senang tapi jarang kita dengar orang buatnya.

Aku perlukan dummy load saja, tak perlu function attenuator is in for variable output/volume.
Ni setup aku.
Amp's Speaker Out -> H&K Red Box -> Mixer
| Quote: | | The Red Box converts your amp's Line Out or Speaker Out(!!) signal into a balanced, frequency-compensated signal that you can feed direcrly into a mixer. The Red Box Classic features two voicing options, a 4x12-inch cabinet and a 2x12-inch combo. |
Red Box tu tap the speaker output, but still takde dummy load.
Dia ada Speaker Thru, still kene hook up kan dengan speaker jugak.
So aku nak eliminate the speaker in this equation, ganti dengan dummy load.
The point of all this is, aku nak power tube nye tone minus the harshness of guitar amp's speakers (aku ada ear injury).
The mixer will be connected to a studio monitor.
I'm thinking of 8 ohm, 100 watt dummy load. |
