    Bowers & Wilkins New 800 Series Diamond Raises the Bar with Revolutionary Advancements

    Hi, I love the B&Ws ... I would have the 801 but I would need a bigger apartment. the 18%: 803 D3 list price was 17K if I remember correctly. The mention to smoke and mirrors is not in my post. I think these exoteric market gimmicks depreciate the products and the company, and justify my...

    Bowers & Wilkins New 800 Series Diamond Raises the Bar with Revolutionary Advancements

    Yeah, I am sure the Biometric (what is this?) Suspension justifies the 18% price tag increase ... I have a 803 D3 , I like them but B&W is going overboard with this kind of exoteric marketing descriptions.. well, they are now part of a holding company...

    Resistive Load for Amp Testing

    "I'm thinking that wiring the elements in parallel will combine the wattage." Yes, I see what you mean. The total dissipated power will be doubled (for a 2 resistor net) because the resistance will be halved, the total current doubled for the same amp output voltage but each individual...

    Resistive Load for Amp Testing

    The dissipated power depends on the voltage put out by the amp, and that is dependent on the volume. The P (in Watts) = V**2 (in Volts, voltage squared) / R (in ohms). The watts (max) spec for a resistor may have some lattitude depending on the heat dissipation, in your case a lot. Once I used...

    Resistive Load for Amp Testing

    I am not sure regarding the wiring you mean, let me try. Following the Ohms law you could use the patch cables to combine the 8 ohm individual resistors, either in parallel, in serie or both, to the desired resistance (I use resistance, since it will not be an inductive load to use impedance...

    REW rephase convolution IR delay 'centering'

    Hi everyone, I use REW and rephase to create a param gain EQ IR for a convolution in JRiver mostly for attenuating some bass peaks (no changes up from 300Hz) . A pretty basic use I thought I understood until I decided to run REW to check the convolution using the very useful functions John...

    REW Beta Release V5.20 beta versions 19 to 28

    Just a small detail regarding the Info window.. (Beta 24) When playing from file (in Measure Playback From File), Excitation in the Info window shows whatever Level was set before when Playback was set to From REW which may or may not be the same as in the generated sweep file.

    System Delay interpretation

    Hi everyone, What is the System Delay when using Acoustic Ref, playing from file, and the ref speaker is the same one being measured? If the acoustic ref is the starting point to measure delays wouldn't under those conditions every delay be the same at the mic and in the system? Is it a...

    Feature request: Measure- a sweep played from a network player

    Hi John, thanks for your dedication to REW, actually to us, the users of your capo lavoro. please consider adding an option to make a measure using a pre-generated sweep (now that two acoustic timing refs are possible), saved, uploaded, and played directly from a network player. Similar to...

    REW Beta Release During measures, output channel set is always changed to Both.

    Hi John, many thanks. I failed to notice this when no timing or acoustic reference is used. I was/am trying to setup the loopback using soundflower and linein on the mac, and since I started on the Beta version, well.. And my deepest appreciation for all the work you have put in REW. It is a...

    REW Beta Release During measures, output channel set is always changed to Both.

    REW V5.19 Beta 8 Macbook pro - OS X 10.13.3 JRE 1.8.0_102_64 Make a Measurement changes the selected Output Channel to Both Preferences set the Output Device Channel to Right (or Left)... Click Measure opens the "Make a Measurement" window, set channel to Right (or Left).. Start Measuring...
