TS112a - Achieving Maximum Output

The TS112a has 2 channels and is rated at 400w continuous. Does that mean that each channel has a maximum output of 200w continuous such that I'd need to use both channels to achieve the speaker's 400w continuous capacity?

    Sorry not sure what you mean, "has 2 channels" it has 2 inputs meaning that you have control over what you feed in, the loudspeaker itself is rated at 400w continuous at full output which is about 200watts RMS which to be fair is good for a very small room if you are happy with that. My friend has 4 x TS115's and wanted more power so we exchanged the 15" drivers for better & more efficient model i.e. Eminence Kappa -15C, as he had four of these we compared the one we upgraded and the difference was doubling the SPL output, not surprising with the dirt cheap original driver that we took out, the built in amp runs @ 4 ohms for the maximum output so if you want to improve your 12" driver you can do the same use the Eminence Kappa 12A (4 ohms) when you replace any driver look for the sensitivity spec. every 3dB is effectively doubling your sound output, the Kappa 12A is 99dB (this is the SPL, sound pressure level rating for 1 watt @ 1 metre), I doubt if the 12" driver they use is more than 95dB, mind you you get what you pay for. I hope I have helped you.

  • Thanks for the feedback Phil. I may in fact trade the TS112a's out in the future but for now they do fine for gatherings of 150-200 - especially since I run them on top of QSC 212c subs crossed over at 100hz. They are rated at 800w peak which i believe translates to 400w continuous. Let me know if you agree.

    With regard to my original question, I simply wanted to know if I could get the speaker's maximum performance from a single input or whether I needed a Y adapter and engage both inputs simultaneously to get maximum performance.

  • Ok Obie I now see what you are asking, the input control is the governing factor here, if you need to increase the control fully clockwise and notice that its not clipping (red indicator) then you need to increase the input from your source i.e mixer.
    My system is 4 way active but using external amps. 21" Sub, 18" Bass, 2 in no.10" mids and 2 in no.compression horns. Running 4 in no. Yamaha amps.

  • Bro, that's some serious power. OMG!!! I would need a trailer and a hitch to haul that around. All the best and thanks again for the feedback.

  • Sorry I forgot to answer the other question, when a company quotes peak its very deceiving really and has no relevance, i.e. 800w like you say = 400w continuous = 200 watts RMS as a guide line, the PD 21" driver (2150) in the subs are rated at 1,000 watts rms the 18" are 800w rms the 2 x 10"= 600w rms the 2 horns =100w rms which equates to a 5K rig and that would be it, I couldn't call it a 20,000 watt rig, albeit there are people out there that would, but 5K is what it can handle, the sound pressure level depends on the efficiency of the drivers and cabinet design, Sub and bass could be 6dB increase if they were a folded horn design with the midrange having an exponential horn design (flared arrangement) also will give a 6dB increase, remember every 3 dB is doubling the sound so a 5K rig using the above criterion would sound around 4 times louder. I hope this helps.

  • When I'm not gigging I leave it set up at the bottom of my garden and give it some welly now and again, It does sound the business.
