It is based on solutions known from the well-rated and extremely popular V3 model, including the TI \u003cb\u003eTPA3255\u003c\/b\u003e amplifier, an efficient heat dissipation system or the possibility of replacing operational amplifiers. ZA3 has been enriched with a number of novelties, such as \u003cb\u003ebalanced XLR\u003c\/b\u003e input, \u003cb\u003eoutput for active subwoofer\u003c\/b\u003e or 12 V trigger connector.\u003c\/p\u003e\u003cp\u003eAll this makes the Fosi Audio ZA3 the most competitive speaker amplifier in this price range. The model works great as a classic stereo amplifier, fits perfectly into 2.1 sets with an active subwoofer, can be used as a \u003cb\u003emonoblock\u003c\/b\u003e (PBTL mode) to achieve higher power and total channel separation (set of two ZA3), and is one of the most affordable amplifiers with a balanced input. \u003cb\u003eThis product is worth a lot more than its price would indicate.\u003c\/b\u003e\u003c\/p\u003e\u003ch2\u003eFosi Audio ZA3 created by V3 users\u003c\/h2\u003e \u003cp\u003eFosi Audio model ZA3 shows not only that it is developing its offer in a thoughtful way, but also listens to user opinions and responds to their suggestions. Many people using the V3 model indicated that the product could still gain if it was equipped with a balanced XLR input and the ability to work in mono mode. The Fosi Audio team decided to meet expectations.\u003c\/p\u003e \u003cp\u003eThis is how ZA3 was created, which is the result of countless schemes and sketches, and later prototypes that were rigorously tested. This amplifier draws the best solutions from the popular V3, and introduces further additions to exceed the requirements of users - the model has not only a balanced input and mono mode, but also an output for active subwoofers or a trigger input for easy cooperation with other elements of the audio set. Fosi Audio ZA3 is an example of how a good product can be created thanks to the joint efforts of the manufacturer and users.\u003c\/p\u003e\u003ch2\u003eFosi Audio ZA3 with balanced XLR input\u003c\/h2\u003e \u003cp\u003eThe Fosi Audio ZA3 has not only a traditional line input (RCA), but also a balanced XLR input (2 x 3-pin. It is one of the most affordable speaker amplifiers with symmetrical input on the market. Users can easily switch between them using the switch on the front panel.\u003c\/p\u003e \u003cp\u003eThe model has speaker connectors (under banana plugs or the cable itself) and an additional RCA output for subwoofers, so it is a great option for driving 2.1 sets with active subwoofers. The Fosi Audio team took care of the 12 V trigger, thanks to which the amplifier can be automatically switched on and off along with other elements of the audio track.\u003c\/p\u003e\u003ch2\u003eFosi Audio ZA3 with powerful TI TPA3255 amplifier\u003c\/h2\u003e \u003cp\u003eFosi Audio ZA3 has an advanced amplifier circuit that operates in class D. It is based on Texas Instruments' high-quality TPA3255 chip with excellent current efficiency. The model has a maximum output power of 2 x 180 W for a load of 4 Ω (with a 48 V power supply), which enables efficient drive of many passive speakers.\u003c\/p\u003e \u003cp\u003eThe company used a potentiometer with logarithmic characteristics, thanks to which the volume control system is better suited to the characteristics of human hearing. The ZA3 model also has a protective circuit that protects the connected speakers.\u003c\/p\u003e\u003ch2\u003eFosi Audio ZA3 can also work in mono mode\u003c\/h2\u003e \u003cp\u003eThe ZA3 can be used in mono PBTL mode, which allows you to increase the output power to 235 W for a load of 4 Ω (with a 48 V power supply). Thanks to this, users can use two amplifiers as monoblocks, which guarantees not only better driving of demanding speakers, but also sensational separation between channels. Fast switching between stereo and mono mode allows the switch placed on the front panel.\u003c\/p\u003e\u003ch2\u003eHigh-end audio components in Fosi Audio ZA3\u003c\/h2\u003e \u003cp\u003eThe Fosi Audio team used high-quality audio components in the ZA3 amplifier. Among them are m.in. Japanese NCC 63V\/2200uF capacitors, Japanese Sumida Audio induction coils, foil capacitors of the German brand WIMA or electrolytic capacitors of the Japanese brand ELNA. All these components made it possible to achieve great sound quality.\u003c\/p\u003e\u003ch2\u003eEfficient cooling system for Fosi Audio ZA3\u003c\/h2\u003e \u003cp\u003eFosi Auio ZA3 is enclosed in a housing made of resistant aluminum alloy with a sandblasted black surface. The manufacturer - like the popular V3 model - used its own heat dissipation system, which is extremely effective. It is based on a heat sink on a printed circuit board and special ventilation openings. This guarantees great airflow and efficient heat dissipation.\u003c\/p\u003e\u003ch2\u003eFosi Audio ZA3 with interchangeable OPAMPs\u003c\/h2\u003e \u003cp\u003eFosi Audio enables the replacement of operational amplifiers in the ZA3 model. This allows you to replace standard OPAMPs with other solutions to achieve different sound signatures. What’s more, users can independently change the operational amplifiers for line input, balanced XLA input and subwoofer output.\u003c\/p\u003e \u003cp\u003eFosi Audio V3 as standard is available with a better \u003cb\u003e48 V\/5 A\u003c\/b\u003e power supply.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTechnical specification of Fosi Audio ZA3\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003edimensions: 155 x 184 x 51 mm\u003c\/li\u003e \u003cli\u003eWeight: 838 g\u003c\/li\u003e \u003cli\u003eamplifier: Texas Instruments TPA3255\u003c\/li\u003e \u003cli\u003eSINAD: 89 dB\u003c\/li\u003e \u003cli\u003eSNR: 106 dB\u003c\/li\u003e \u003cli\u003eDynamic Range: 106 dB\u003c\/li\u003e \u003cli\u003eTHD: 0,006%\u003c\/li\u003e \u003cli\u003efrequency response: 20 Hz - 20 kHz (+\/- 0,1 dB)\u003c\/li\u003e \u003cli\u003eSpeaker Impedance: 2-8 Ω\u003c\/li\u003e \u003cli\u003eOutput power (4 Ω; stereo; 48 V power supply): 2 x 180 W\u003c\/li\u003e \u003cli\u003eOutput power (4 Ω; mono; 48 V power supply): 235 W\u003c\/li\u003e \u003cli\u003eInputs: Linear (RCA), Balanced (2 x 3-pin XLR)\u003c\/li\u003e \u003cli\u003eOutputs: speaker (wire, bananas), for active subwoofer (RCA)\u003c\/li\u003e \u003cli\u003etrigger input: 12 V\u003c\/li\u003e \u003cli\u003epower supply: DC 24-48 V\u003c\/li\u003e \u003cli\u003ePower supply included: 48 V\/5 A\u003c\/li\u003e \u003c\/ul\u003e\u003cp\u003e\u003cb\u003eAbout Fosi Audio\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eFosi Audio is a young manufacturer of audio equipment that has been operating on the market since 2017.
