Technology<\/h4>\n
As in the T+A P 3000 HV<\/strong>, the circuit topology of the amplifiers is based on a cascode differential amplifier with hand-selected audio J-FET transistors and completely discretely constructed stages without an operational amplifier. This circuit concept and the quality of the components means that virtually no over-all-counter-coupling is necessary. Thanks to its high operating voltage, the HV<\/strong> technology also allows extremely high linearity as well as an extremely high dynamic range. Signals up to 60 Vpp can be processed undisturbed.<\/p>\n In the T+A HV series<\/strong>, switching and switching functions in the signal range of gas-tight encapsulated gold contact relays are adopted which, even after many years of operation, do not have any contact problems due to corrosion, dust, etc. and no ageing.<\/p>\n In the preamplifier, bi-stable relays are used in which no permanent coil current flows anymore and thus also no inductive impairment of the audio signals can take place. Due to the integration of the relays directly into the circuit, the signal paths are optimally short and there are no cable paths, such as conventional volume potentiometers. The volume control is also built with discrete precision resistors and gold contact relays, so there is absolutely accurate channel balance, no noise and no distortion.<\/p>\n The entire control electronics are deeply recessed and shielded in the 40 mm thick and fully milled front panel, on the front of which is the luminous and dimmable display (VFD) made of glass with wear-free sensor buttons.<\/p>\n <\/p>\n The T+A PA-3100 HV<\/strong> is a further development of the PA-3000 HV<\/strong> and is identical in most modules. The immediately visible difference is two VU meters in the front, which display the output power per channel logarithmically in watts at 4 ohms. In addition, a new concept for the analogue converter part and the voltage supply was developed similar to the A-3000 HV<\/strong>, which allows the PS-3000 HV<\/strong> to be connected and the stability and performance of the entire voltage supply to be increased again.<\/p>\n","protected":false},"featured_media":38112,"template":"","meta":{"_acf_changed":false},"product_brand":[778],"product_cat":[314],"product_tag":[],"class_list":{"0":"post-38110","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-ta","7":"product_cat-integrated-amplifiers","9":"first","10":"instock","11":"taxable","12":"shipping-taxable","13":"purchasable","14":"product-type-variable"},"acf":[],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product\/38110","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":1,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product\/38110\/revisions"}],"predecessor-version":[{"id":49303,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product\/38110\/revisions\/49303"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/media\/38112"}],"wp:attachment":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/media?parent=38110"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_brand?post=38110"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_cat?post=38110"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_tag?post=38110"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/hifimarket.ee\/wp-content\/uploads\/2025\/08\/TA-SDV-3100-HV-Reference-Preamplifier-Streaming-DAC-desc.jpg\")
