| Amp output to 2 speakers Sounds good! And thanks for the feedback.Regarding the RCA-to-XLR cables, be sure to note that per Figure 2.1 of the Jensen paper I referenced in the earlier thread the cable should be two-conductor shielded (which is what is generally used in XLR... | |
| Amp output to 2 speakers I don't understand the references to splitting and combining. If I interpret correctly that you are addressing insertion of a KUBE into the signal path to the single amp channel that is driving the paralleled R102's, just use one channel of the KU... | |
| Amp output to 2 speakers Why is a parallel connection preferable? 1)Overall sensitivity and maximum overall volume will be approximately 6 db less for a series configuration than for a parallel configuration. 6 db corresponds to a factor of 4 difference in power delivery.... | |
| Amp output to 2 speakers DB, both amps provide three channels of amplification, and the dual sets of output terminals that are provided for each channel of the Amp 3 are undoubtedly just wired directly together inside the amp. So you have not been biamping the R107/2's (i... | |
| Thoughts on very cheap speaker cables Correction to my first post above: The reference to "between about 10% and 20%" should have said "between about 5% and 10%."Regards,-- Al | |
| Watts up with that? Since the majority of the load is mostly reactive below 200 Hz this is a terrible "resistive" load per your conclusion. It is NOT a resistive filament. No where near. It does produce a very reactive signature to the majority of the signal power be... | |
| Thoughts on very cheap speaker cables Connecting two of the conductors in parallel would of course reduce the resistance by a factor of 2. As you can see in the wire gauge table, a factor of 2 change in resistance corresponds to an increment of 3 gauge sizes. So you would have the equ... | |
| Thoughts on very cheap speaker cables I was hoping to get some responses about the negative or positive aspects of using only 2 22 awg solid wires per channel. The gauge is inadequate for neutral behavior. AWG 22 wire has a resistance of about 16 ohms per thousand feet. The 24 foot ro... | |
| Which is Your Favorite Marantz Amplifier? You may not have had in mind the tube-based amplifiers made by the original Saul Marantz company, but my nomination would be the Marantz 2 monoblock power amplifier.Manufactured during the late 1950's and the very early 1960's, they are unquestion... | |
| Splitting a pre-amp channel for sub - good or bad? Not a good idea in this particular case. As we discussed in one of your other recent threads, you may already be approaching the point of impedance incompatibility between the preamp and amp. If you split the signal it is likely to make that situa... | |
| My JL Audio sub is dead. What exactly happened? Hi Bryon,My sympathies on this also. Hopefully it will just turn out to be a fuse, as Tesseract suggested.Is there any sign of life from the sub, such as LEDs illuminating? Or is it totally inert, as if an AC line fuse is blown?Do you use the sub ... | |
| Who is Most Beautiful female singer ever IMO a good case could be made for Connie Francis, when she was in her prime.Honorable mention to the late opera singer Anna Moffo.Regards,-- Al | |
| 1.2k Output Impedance to 10k Input Impedance Hi Scott,IMO, the impedance matching guideline is properly stated as follows (I'm quoting from myself in another thread):Ideally the input impedance of the power amp should be at least ten times greater than the output impedance of the preamp, at ... | |
| DAC burn in question No. The input impedance of the amp, and hence the amount of current that it draws, is most likely determined primarily by resistors that are connected to its inputs. Those resistors will draw the same amount of current regardless of whether or not... | |
| using a jumper cable - connect which set of post? As can already be seen in this thread, opinions on this question will inevitably be diverse. Some people say to use the low frequency posts, some say to use the high frequency posts, some say it doesn't matter, and in past threads you will find so... |
