| The Importance of the Digital Cable This is not true. As mentioned by several here; the "digital" signal is actually electric and any ic might do a ok job, just try. Don`t let the salesman fool youThis is not true. As mentioned many times here digital signal is affected by time jit... | |
| Low gain amp system matching @lowrider57 They had two versions of M3: pre i post October 2013. Both have gain of 18dBHere is user manual that reflects it: https://d1b89e86-9572-4311-9f80-60009b280608.filesusr.com/ugd/3e7c3b_cb9f60cb6a26418992b53df75192a77... | |
| Question on Preamp Outputs. As for the output being always 450W. It is always 450W because for different speaker load transformer has different output voltage (amp has different gain). 8ohm speaker would normally produce half of the 4ohm speaker, but amp’s gain for 8ohm outp... | |
| Question on Preamp Outputs. So what? This amp has double gain at unbalanced input (26dB vs 20dB), for the output power to be 450W at nominal voltage at given input, but output voltage will be a linear function of input voltage at given input. If you lower voltage at given ... | |
| Question on Preamp Outputs. His pre outputs 2.4V for balanced output. His amp outputs 450W for 4.2V balanced input.Amplifier’s output voltage will be a linear function of the input voltage. It has to be or amplifier will have huge distortions. Output power P = V^2 / R If you... | |
| Question on Preamp Outputs. look at the specs for the 462 amp! Both 2.1 and 4.2 volts both produce output wattage of 450! Both 2.1V and 4.2V produce the same wattage of 450W but from different inputs (balanced and unbalanced) that have different gains.Gain for this amp for 4... | |
| Question on Preamp Outputs. It is exactly what it is. His amplifier has 20dB gain for balanced input at 4ohm output posts. 20dB is10x. When you input 4.2V input output becomes 10 x 4.2V = 42V P = (42V^2) / 4 = 441WAt 2.1V input output becomes 21V P = (21V^2) / 4 = 110.25W | |
| Question on Preamp Outputs. jasonbourne52 You multiply power by the ratio of voltage and that is wrong. It is not linear problem since output power is function of input voltage squared. For instance 1/2 of voltage = 1/4 of power. | |
| Question on Preamp Outputs. Here's the math: 2.4 ÷ 4.2 = .5714 × 450 = 257.14 watts into all impedances! Power is proportional to voltage squared (2.4/4.2)^2 x 450 = 147W | |
| Low gain amp system matching @radiohead99 Voltage gain of your preamp is about 8x. In order to obtain 0dB gain (2V input, 2V output) you need to set wiper at about 50% (12 O'Clock) position (to divide by 8). Since ideal position would be around 2 O'Clock (with extra gain ... | |
| Low gain amp system matching 1V output for 126mV input is 18dB (not 15dB)If your DAC produces 2V nominal, then preamp output will be 2V x 1/0.126 = 15.9V - way too much for an amp with 2V nominal input.Perhaps your DAC has jumpers to reduce gain by 10dB (like in my Benchmark ... | |
| Which component to upgrade to improve bass control? A Hegel h390 has terrific bass control. Damping factor of 4000. Damping factor, in spite of the name, has very little to do with membrane damping because there is speaker’s own coil in series for the braking current. 8 ohm speaker has about 6 ohm ... | |
| The Importance of the Digital Cable Yes, electrical noise will be very important contributor affecting not only transmission (creating time jitter), but also polluting everything else. Reflection created jitter in cable plays separate role. Reflections will produce time jitter of th... | |
| The Importance of the Digital Cable Yes, cable delivers digital information to D/A converter to produce analog (audio) signal. When this information is delivered in exactly same intervals then everything is always the same - perfect reproduction, but the problem is, that exact momen... | |
| Is There A Reason for Mono Amps for Ultra-low Noise Class D Modules? It’s hard for me to imagine that two boxes of the same size would be easier to place than one box in a room.It will be, especially for the large units. You can always shove them together if you want to have single unit.The advantage of greater hea... |
