【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】
■ Voltage Compatibility
This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).
Many regions use 120V or 220–240V.
Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.
■ Plug Type
This product uses a Japanese plug (Type A or B).
A plug adapter may be required depending on your region.
■ Transformer Requirement (Very Important)
A transformer is required for safe use.
A plug adapter only changes the plug shape and DOES NOT convert voltage.
Using this product without a transformer may cause serious and irreversible damage.
■ Buyer Responsibility
As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.
■ No Return / No Refund Policy
We do NOT accept returns or refunds for:
・Voltage mismatch (including 120V and 220–240V environments)
・Use without a transformer
・Plug incompatibility
・Damage caused by improper setup or usage
■ Liability
We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.
■ Final Notice
Please ensure full understanding of the above before purchasing.
Use only under the correct voltage environment.
Equipped with the TPA3255, this compact amplifier delivers a high output of up to 300W x 2: The amplifier section employs Texas Instruments' high-end Class D amplifier chip, the "TPA3255." It achieves a maximum output of 300W x 2 at a 4Ω load, effortlessly driving everything from low-efficiency bookshelf speakers to floor-standing models. It combines the high efficiency (low heat generation) characteristic of Class D amplifiers with low distortion thanks to its advanced feedback design. Despite its compact size, it delivers overwhelming sound, making it the centerpiece of home theaters and desktop Hi-Fi systems.
Independent Analog VU Meters + Balance Control: Based on feedback from users of the previous model (H7), the H7 PRO features newly added independent analog VU meters for the left and right channels. The needles move in real time in accordance with the dynamics of the music, enriching the visual listening experience. In addition, independent volume control for the left and right channels has been eliminated and replaced with a balance control for fine-tuning the sound pressure balance between the left and right channels. You can adjust the optimal stereo image according to the speaker placement environment and listening position.
Expandability with RCA + Balanced XLR Inputs and Pre-Out Outputs: In addition to standard single-ended RCA inputs, it is equipped with noise-resistant balanced XLR inputs. This allows for clean signal transmission even in long-distance wiring or in locations with complex electromagnetic environments. Furthermore, it has a pre-amp RCA output, making it easy to connect an active subwoofer or another power amplifier to build a 2.1ch or multi-channel home theater system. The output terminals are banana plug compatible speaker terminals.
Audio-Grade Components and High Reliability: To pursue both sound quality and durability, high-quality components are used internally. These include filter capacitor arrays from Japanese manufacturers ELNA and Rubycon, professional audio inductors, and fully sealed precision potentiometers. This achieves an S/N ratio of over 110dB and an ultra-low noise floor. Furthermore, the design ensures sufficient heat dissipation area, maintaining stable performance even during prolonged high-power operation.
CNC-machined aluminum casing and sophisticated design: The casing is made of a customized aluminum alloy using CNC machining. It boasts high rigidity and heat dissipation, and the cool feel and substantial weight when you hold it convey a sense of reliable quality. The retro charm of the VU meter harmonizes with the modern, minimalist design. Whether placed on a desk or audio rack, it makes a strong statement as part of your interior decor.
The H7 PRO is a stereo digital power amplifier equipped with TI's flagship Class D amplifier chip, the TPA3255. With a maximum output of 300W x 2 (4Ω), it powerfully drives most passive speakers from 4Ω to 8Ω. In addition to RCA inputs, it features noise-resistant balanced XLR inputs, making it suitable for professional audio environments. Furthermore, the preamplifier RCA output allows for expansion to 2.1ch or multi-channel systems by connecting a subwoofer or another power amplifier. A distinctive feature of the Max. model is its independent left and right analog VU meters, where the needles move in sync with the music signal. This retro-modern unit allows you to enjoy music both aurally and visually.
