    Question Does a Mixer change audio tone quality?

    Sign in to disable this ad
    Hi
    I was impressed by a certain streamers radio/broadcaster sound/tone quality and asked if he could turn off his processing so I can get a before and after.

    The broadcaster like sound quality is something I've been trying to replicate.

    I use a: Rode Procaster DBX286S Zoom UAC2

    I was shocked by the difference as I have similar equipment. A clip from his stream: https://clips.twitch.tv/CarelessHungryWormBabyRage

    Looking at his audio equipment he has: Shure SM7B DBX 286s (Mic Pre Amp/Processor) Behringer Xenyx Q802 Roland VT-3

    My question is does his his mixer add that broadcaster tonal effect? Or is the SM7B the sole reason as from what I read a mixers function is to just organize multiple sources.

    He was kind enough to send his DBX settings which I replicated on mine and it's nowhere near the same.

    I was thinking of buying a yamaha mg10xu or allen heath zed 10fx if it did indeed give that sound tone but I thought I'd ask the pros first before spending money.

    Thanks

    That's most likely the MIC. But, a mixer will degrade audio to some degree - that just comes with complicating a circuit

    A Behringer mixer certainly is not going to impart a 'broadcast' sound.

    The poster just said the q802 was in the chain. haha Actually, I think there's a ton of the SM7b going into quite modest Behringers on streaming

    You're not hearing the mixer.
    What you like is either his voice, the microphone, the room, the processing, or some mixture of those.

    Proximity to the mic will play a big part. Get close to the mic for that boomier, and drier, sound.
    If you're even a few inches farther away than him (as you can hear when he leans off to the side), you'll lose a lot of bass and you'll hear room ambience a lot more.

    Sounds like he's scooped the mids or boosted the bass, and compressed the balls out of it too.

    Thanks for the replies. He has provided screenshots of his 286S settings which he bypassed in the clip.

    As I mentioned apart from the gain settings I copied his settings and couldn't get that warm, full bodied broadcasater type tone. The reason I didn't increase my gain is that I have a Triton Fethead preamp going into my micrphone.

    This is what I had my DBX at. The settings were from following youtube guides and adjusting it for my room.

    He hasn't any pics of his mixer because he mentioned he changes them frequently to tailor the sound. At the moment, bass and mids are up (mids slightly higher) and treble is lower. Nothing breaks 50% though.

    The only REALLY classy thing in that broadcast chain is the SM7b! After making the PSU, case and other bits, $200 does not leave a lot for a high end mic amp in the DBX, I fact I doubt it is much, if any better than the mic pre in the Berry.

    Now, mic preamps in budget kit have a problem. To get a low noise performance (and most are V good in that respect) they use a hybrid amplifier. The downside of that is the mic amp produces more harmonic distortion than the rest of the mixer/strip electronics. This is at its worse at high gains, just what the 7b needs!

    But, I am really with the other guys, the sound is mostly down to room and vocal quality/technique. Like, you can have all his kit but you will never sound like Clapton!

    I loaded up Audacity and had a fiddle. It seems a high compressor ratio and and LF detail is what is giving that sound. Additionally, like what's been mentioned he is further manipulating mids in the mixer. The SM7B also has a better freq response which is probably helping with the audio quality (50 to 20,000 Hz) compared to my Procaster that has (75 to 18,000 Hz)

    Now my requirements have changed and I have slightly more knowledge thanks to you guys I guess I should go for the SM7B and a good quality USB mixer with a decent preamp.

    What mixer would you recommend for 300 that has a USB interface?

    I will buy a condensor mic like the SM7B or maybe a Heil PR40 or even a rode nt1-a depending on how much money I have left in the kitty and keep the DBX2896 as it has a okay noise gate, de-esser and compressor for Twitch. I can flog the Zoom UAC2 and Rode Procaster and the money raised can go towards funding the upgrade.

    Thanks again.

    I don't know if there is a need for a better mixer. Maybe a 802 with effects. There is also the RE320 MIC.

    Whoa there Twirly! Firstly, the SM7b is a DYNAMIC mic and a damn good one. If you need a mixer in the system add a Cloudlifter to amp up the mic as that will allow the mixer pre to be backed off by some 25dB with a consequent reduction in distortion of an order.

    Are you driving the mixer's main outs into the Zoom? If so you might like to try putting it an FX send/return instead? (I bet 'The mane' is doing that!)

    Tis all a bit of a shame really because the UAC-2 is noted to have truly excellent mic amplifiers.

    Dave.
