Clickrepair registration code4/5/2024 Looking at the earlier posts this preamplifier has been discussed in the past on the forum and on Keith Snooks site plus on the Trader sheet. The QCII’s are later units, Serial # 1470 putting them just above and below the 17000 ‘third version’ change point with the two versions of the EQ. ![]() The tone controls and low pass filter on the QCII will be useful to tidy up the signal, given the limitations of the available EQ curves. The plan is to place a workshop brewed buffer, with a gain/attenuator control and a high pass filter to remove LF noise (the QCII doesn't have one), between the output of the QCII preamplifier and the input of an external Sound Blaster SBX ADC. I’ve had a look in the toybox, and I have two Quad QCII preamplifiers. I know it’s being nostalgic, but I want to perform the phono EQ in the analogue domain using a ‘period’ valve preamplifier so that means I’ll need a suitable period valve preamplifier for use with the Audio-Technica AT-VM95 78RPM cartridge fitted to a Goldring GL75. Of late I’ve not really thought much about 78 RPM records, except for the occasional one bought at a charity store and played on my Black Box or Bush record player… And there were the ones I came by as young Lad with radiograms and suchlike which, met with a sticky ‘frisbee’ like end against the garden wall… Ooh, the days of being given an old radiogram with a selection of 50’s 78’s… The 78 I remember was Hang Down Your Head Tom Dooley, but I digress… As far as I know most are of UK origin, but I’ll know more when I get to see them. I have no idea of the state of them and how worn they are. Reading these posts makes me think I’m barking up the right tree using a Quad QCII preamplifier for 78 playback duties.Īnway, I’ve been asked to copy over a selection of a late husband’s 78 record collection, which pretty much spans the 1950’s, over to MP3 for playback on ‘modern’ equipment. I’ve just trawled the forum and found two cracking posts dating back to 2010 as regards playing 78’s. The French Manual has also been updated by Philippe Bonin.That ‘ole chestnut… Playing back 78RPM records. The manual has been expanded as a result of these changes. Visual feedback has been updated to allow the user to simultaneously monitor the operations of declick, decrackle, and pitch detection. However, the maximum sensitivity (100) remains unchanged, for the benefit of users with older material. The detection and repair algorithms have been improved – with the new version it is much more likely that marginal and/or false repairs will amount to minor changes.įollowing user feedback, the sensitivity settings have been re-defined, with the new numbers (0–100) corresponding to lower sensitivity than in version 1.3.2. Both of these restrictions have been removed. The previous method for shellac (78) material involved both pre-mixing and post-filtering. The previous method for mono material, which simply pre-mixed to a single data stream, is replaced by independent treatment of the channels, followed by an automatic merge. ![]() There is a new algorithm for protection of brass instruments and other highly pitched material. ![]() The previous method of processing each channel as a single stream are still available as an option (with some improvements to the algorithms). There is a new processing method which splits the audio data (in each channel) into two streams, using the theory of wavelets. Some of the changes will be obvious (to existing users) from the interface. Version 2.0.1 (build 33c) released September 21, 2006:ĬlickRepair 2 is greatly changed and enhanced compared to the previous version 1.3.2. Version 2.0.2 (build 33d) released October 21, 2006:įixed bug which could cause processing to stall in some exceptional circumstances.
