Whakaahuatanga Hua
1. Whakarāpopototanga o te Hua
He mea motuhake mō te hanga whatunga. He porowhita kiato teitei, he koranu konumohe hoki, he papa kume o te mata, he pai te taupū me te āhua pai.
2. Āhuatanga hua
- Whakamahia te kōwae RF whakakī SOT-115 i te urunga, he pono, kāore he raina. Kōwhiria he ara iahiko pana-tō iti-haruru, he iti te hē, ā, he teitei te ōwehenga S/N.
- Whakatūria te EQ me te ATT ki te wāhi tika, kia māmā ake ai te rapu hapa.
- He iti te whakamahinga hiko, he nui te pono, he pai te mahi me te ōwehenga utu.
