Neurochrome (Canada) er ute med en ny versjon buffer for hele Purififamilen av forsterkermoduler. Samt Hypex NC500. Sistnevnte er vel ikke så aktuell da den er forbeholdt OEM.
Ser ut som Tom Christensen ikke har gjort seg bort denne gangen heller. Spesifikasjoner i spitzenklasse ! Forøvrig så er denne ferdigbygd. Så det er bare plugg og spill. Usikker på om den er form and fit ift f.eks EVAL 1 bufferen til Purifi (Skruehull etc).
Kremt hrrmff 1: Den har forøvrig 8 pins sokkel på Op-ampen slik at Hiendismens menighet kan bedrive sine ritualer og sådan oppnå en høyere tilstand "der oppe" . Vel beskrevet tidligere i tråden.
Kremt hrmmff 2: Armand har vel noe å strekke seg etter her, hvis han ikke har "dunket inn ballen" allerede ? Gung ho !

This input buffer is designed for the following Purifi and Hypex Class D amplifier modules: 1ET400A, 1ET6525SA, 1ET7040SA, 1ET9040BA, and NC500.
Key advantages:
- Fully differential output for full power, even with a single-ended source.
- Controlled common-mode voltage to prevent power supply bus pumping.
- Four independent ultra low-noise voltage regulators for analog and digital power.
The buffer is a single-channel (mono) buffer, with the following features:
- Differential (balanced, XLR) input, which can easily be configured for single-ended (unbalanced, RCA) operation.
- Fully differential output even when used with a single-ended source.
- Common-mode feedback ensures zero common-mode output voltage to avoid power supply bus pumping.
- Jumper-selectable gain: 11.6 dB, 13.0 dB, and 13.2 dB for a total amplifier gain of 26.0 dB when used with the Purifi Class D modules.
- Gain can be further customized by adding a resistor (1206 size SMD and leaded/PTH supported) or set to unity gain (0 dB).
- Plug-and-play connection with Hypex SMPS1200 power supply.
- Four ultra low-noise voltage regulators power the analog and digital circuits of the Buffer and the amplifier module. Optionally, you can add the Hypex HPR/HNR regulators.
- Speaker output is provided on 6.3 × 0.81 mm quick-connect spades and a terminal block accepting up to AWG 10 (5.2 mm2) in size.
In addition, the following options are provided for advanced users:
- By adding a resistor and a 7-pin connector, the amplifier module can be operated in software mode. See the relevant amplifier module data sheet for details.
- The buffer can be disabled by removing two resistors. A 3-pin connector footprint provides direct access to the input of the amplifier module.
The Universal Purifi Input Buffer circuit board is fully assembled, RoHS compliant, and is designed and manufactured in Canada.
