| Can I use my McComack TLC 1 with a headphone amp Hello Adler_b,Your TLC-1 will work perfectly as the front-end for your headphone amp. You can use either of the main outputs which are volume-controlled, or you can use the Tape Out which is not affected by the volume control. Please note that the... | |
| McCormack DNA-1 Part Needed Hello Efi,Please contact me again about this question. I have designed a new replacement main circuit board for the DNA-1 and DNA-0.5 amps which will be available soon.Best regards,Steve McCormackSMc Audio | |
| McCormack DNA-1 has a clank Hi Guys,The noise is caused by different rates of thermal expansion & contraction between the steel chassis and aluminum heat sinks. It is actually caused by the hardware being too tight, so if you carefully check the hardware to see that it i... | |
| McCormack DNA-1 Protect Mode light glows dimly Hi Bob,Nice to hear that you got your DNA-1 back into service and are enjoying it. The protection circuit monitors DC at the output and shuts-down the amp if it exceeds a certain level. It is possible that it was just doing its job - it may be tha... | |
| McCormack DNA-0.5 Protection Circuit problem? Hi Harold,Apparently your amplifier has some internal damage and will need service. The AC Mains fuse (attached to the AC inlet) has now blown as well, but you should not attempt to use the amp again at this point - the fact that the internal fuse... | |
| SMc Audio: The Interocitor One thoughts? Hi Friends,I am happy to report that the upgrade business is back in action and doing well. My partner Kris is working again and we are busy making great equipment. Please call or write if you are interested in having upgrade work done. Speaking o... | |
| McCormack DNA-0.5 Protection Circuit problem? Hello Harold,In all likelihood you have blown one or more of your 4 internal power supply (rail) fuses. These are 6A or 6.3A fast-blow types (5 x 20mm size) that you can hopefully find locally. Replace the blown fuses and you should be back in bus... | |
| Are Burmester Amps a good match with Aesthetix Pre As already mentioned, the Burmester amps are typically designed with balanced-only inputs, have unusually low input impedance, and run at very high gain. This makes them difficult or impossible to run properly with many tube preamps. I am making a... | |
| McCormack DNA-1 Problem. Help, please Hello Drjay -The DNA-1 (and DNA-0.5, DNA-2, DNA-HT1 & HT2) comes on with the Protection engaged. This lights the labeled red LED which will gradually fade out as the amp warms-up and comes out of protect. This should take less than 30 seconds.... | |
| Upgrade Hafler 9500 or Mccormack DNA-1 for Thiels Bdgregory makes an extremely good point - since you have a DNA-1 on the way, you will be able to audition both amps in stock form. The amp you prefer stock is the one you should stick with.Most upgrades (certainly my own) improve on what is fundam... | |
| McCormack DNA-1 Rev A question Exactly right - thanks, Swampwalker.Best regards,Steve McCormackSMc Audio | |
| 1.2k Output Impedance to 10k Input Impedance Hi Srosenberg,The information you've been given here is good, but it still leaves the question of how best to deal with the issue. I understand that this is not the place for advertisements, so let me simply say that I have developed a good soluti... | |
| Please Recommend a Low Gain Solid State Amp ARC 30dB of voltage gain is slightly higher than average, while an amp with around 24dB gain may be more typical - but the difference is only 6dB, and that won't buy you much additional range on your volume control (very little, in fact). The real iss... | |
| Power of McCormack DNA .5 vs DNA 125 Hi Bjue -The actual measured difference is very small - the DNA-0.5 was rated at 100W into 8 ohms and would hit about 120W before clipping. The DNA-125 is rated at 125W into 8 and will hit at least 130W before clipping. The important difference (i... |
