ETI Research BP-50C guld Binding Post, pris/st

Beskrivning

ETI-Research BP-50C-polskruv är en högpresterande produkt. Tillverkad av 1100-serien härdad koppar med en IACS-värdering på 102%. Du kan vara säker på att ljudsignalen inte försämras genom att behöva gå igenom ett dåligt ledande material som mässing (IACS-betyg 28%).
Koppar är mycket överlägsen mässing när det gäller konduktivitet och som sådan erbjuder ETI-Research BP-50C en nivå av ljudsignalkvalitet oöverträffad i konkurrerande produkter med samma pris.

Längd insidan panel: 50 mm (passar extra bra för högtalare med tjocka väggar)
Längd som sticker ut från panel: 32 mm min.
Diameter hål: 11,5 mm

Specifications

• The post length is 50mm which provides ample length for mounting directly through the backpanel of any loudspeaker cabinet. For use in speaker back plates we recommend to use our ETI-Research BP-20C binding post.
• The housing is made from aluminum covered with a polymer compound. The polymer threads onto the post as to not have any conductive material touching the pure copper. Aluminum is great at rejecting EM/RF noise that is so prevalent nowadays.
• The surface of the copper needs to be closed to prevent oxidation. Our ETI-Research BP-50C has a 24k gold plating applied without any nickel. The plating process does not affect sound quality. Many manufacturers use a nickel surface which is applied before the gold plating process as this is easier and cheaper and makes the gold have a shiny look. The unfortunate problem is that nickel is an extremely poor conductor (IACS rating 24%) and will degrade the audio signal.
• The nut used to secure the ETI-Research BP-50C is made from a high-density nonconductive polymer so that no conductive material is touching the copper post except for what is needed to transfer the Audio signal.
• Securing the wire is by choice either screw or solder.
