I’ve been using this Creatall AS21 amplifier for my home theater setup for a month, and it’s been fantastic! The build quality is top-notch—metal construction feels durable and premium. The TPA3255 chip delivers crisp highs, balanced mids, and deep, punchy bass that fills the room without distortion. Bluetooth 5.1 pairs quickly with my phone and smart TV, and the connection stays solid even through walls. I appreciate the multiple input options (AUX/USB/Bluetooth) that let me switch between devices easily. The protection features (overheat, short circuit) give me peace of mind for long-term use. The company’s customer service was responsive when I had questions about wiring, and the sample delivery was fast (arrived in 7 days as promised). For the price, it’s way better than some expensive brands I’ve tried—highly recommend for anyone looking for a reliable, high-performance amplifier!

Luar biasa! Saya memasang papan amplifier ini di sistem audio ruang tamu saya untuk pesta keluarga dan menonton film. Kualitas suara melebihi harapan, chip TPA3255 memang tidak mengecewakan. Pengaturan treble dan bass sangat halus (tuning stepless sangat keren), tidak ada jeda. Saya sudah mencoba input AUX dan USB, terhubung dengan speaker lama tanpa masalah sama sekali, impedansi cocok dengan baik. Waktu pengiriman perusahaan sangat tepat waktu, barang tiba dalam 5 hari, pengemasan sangat kuat, tidak ada kerusakan. Casing logam memiliki efek pendinginan yang bagus, digunakan secara berkelanjutan selama 3 jam tidak panas, mekanisme proteksi sangat aman. Tersenggol korsleting secara tidak sengaja dan pulih otomatis tanpa perlu restart. Harganya terjangkau, jauh lebih baik daripada produk sejenis di pasar lokal Jakarta, ini pembelian kedua kalinya saya!

यह मैंने खरीदा हुआ सबसे मूल्यवर功放 मॉड्यूल है! मेटल का मटीरियल बहुत मजबूत है, इंस्टॉलेशन बहुत आसान है, मैनुअल के अनुसार 10 मिनट में ही काम हो गया। ब्लूटूथ 5.1 कनेक्शन बहुत स्थिर है, फोन 5 मीटर दूर होने पर भी डिस्कनेक्ट नहीं होता, सबवूफर का 20-200Hz प्रभाव बेहद आश्चर्यजनक है, भारतीय बॉलीवुड गाने सुनते समय ड्रम बीट बहुत ताकतवर है, लेफ्ट-राइट चैनल का व्होकल भी बहुत स्पष्ट है। बल्क ऑर्डर की कीमत स्थानीय सप्लायर से 30% कम है, कंपनी ने मेरे लिए लोगो भी मुफ्त में कस्टमाइज़ किया (मिनिमम ऑर्डर मात्रा पूरी की),कस्टमर केयर जल्दी रिप्लाई करता है, व्हाट्सएप से कम्युनिकेशन बहुत आसान है। केवल एक छोटी सी सुझाव है कि एंटीना को अपने आप खरीदना पड़ता है, लेकिन यूज करने में कोई परेशानी नहीं है, मैंने अपने आसपास के ऑडियो बिजनेस करने वाले दोस्तों को भी रिकमेंड किया है!
