Second Stretch Goal (external in-line control and boost to max SPL)

Posted by Frankenspiel Ltd. (Creator)
Hi everyone,

We’re back with a 2nd Stretch Goal!

This was scheduled for yesterday, but it got pushed back, we just ran out of time. Anyway...

If we reach £66.000 everyone who pledged for at least one FS-X will receive a free (volume control/microphone/mute) in-line control! We’re also going to implement a boost to max SPL (loudness), as always, we will do this without adding distortion.

In designing this external in-line control device we’ve had to take care that it integrates with the existing electronic circuits and that their operation doesn’t:
- reduce any functionality 
- introduce any distortion in the audio path. 

The in-line control includes a microphone (on/mute), audio (on/mute) and volume control (up/down). The in-line controls are attached to a short black cable.

This makes the already versatile FS-X even more versatile still, adding the microphone it becomes a true speakerphone, as well as of course being able to externally mute and control the volume of the FS-X.

Subject to reaching this stretch goal:
1. Backers who pledged for 1 FS-X will receive 1 free in-line control.
2. Backers who pledged for 2 FS-Xs can choose between the following two options:
    - 2 free in-line controls (to also be able to use their FS-Xs separately) 
    - 1 free in-line control and 1 free carrycase!

Identifying your Stretch Goal request(s):

Once the project is officially funded, backers who pledged for 2 FS-Xs will be sent a survey in which they can specify precisely which Stretch Goal they want to have.

So please help us get to this Stretch Goal, by getting the word out to family, friends and/or colleagues! 

Best regards, 

The Frankenspiel Team

- $19 Aluminum Dock for Apple and Android (with or without cases). Compatible with iPhone 5 (C & S) & 6, iPad Air & Mini, Samsung Galaxy S4 & S5, Samsung Note 2 & 3 and more. Maybe use it with the Frankenspiel FS-X?!

      @Frankenspiel, I forgot something! I don't think you understood Giles Smith's question. He said, "Will one in line connector be able to used with a y cable to 'control' a pair of speakers?" In other words, say we connect the two speakers with the Y cable instead of via Bluetooth. Then we plug in the in-line volume control. Will the in-line control both speakers' volume or just one speaker?

      I would assume that it will control both . . . otherwise, it'd be crazy if it only turned one speaker's volume down while the second's volume kept blaring! ;-p

      Also, would the same be true if the speakers were paired via Bluetooth instead of using the Y-cable? Again, logic dictates that it would . . . but just checking!

    2. Marsha Tyszler

      @Frankenspiel, you understood me correctly! I know the mics are intended to be used for speakerphone purposes -- after all, I'm sure the mic isn't the proper quality for recording purposes. Nevertheless, I figured that perhaps it might be possible to use two mics at once for recording song ideas in stereo. Clearly, you're saying that only one mic may be used when two speakers are paired. I hadn't noticed an previous explanation of this, so I'm glad that I checked with you rather than making an assumption. I hope others are clear about this too! :-)

      Similarly, I assume that when two speakers are paired, only one FS-X's internal mic will work and the second will be disabled. Is this correct?

      @ Frankenspiel....

      Kirill's suggestion is valid and logical with regard to a carry case for the pair. It can also be an option for those backing a pair instead of the two options you have given as below:
      "Backers who pledged for 2 FS-Xs can choose between the following two options:
      - 2 free in-line controls (to also be able to use their FS-Xs separately)
      - 1 free in-line control and 1 free carry case"

      Maybe you can add:
      - 1 free neoprene carry case to fit an FS-X pair.

      Cost-wise it might work out the same for you.

      @ Marsha Tyszler: If we understand you correctly the external mic only works on one of the speakers while using them as a stereo pair. The option of two external in-line controls is for backers who intend to use their FS-Xs seperately. Bear in mind that the microphone in the external in-line control is intended for use as a speakerphone.

      @ lee gibson, bsl100, Laurence Freedman, Danny Dierickx, Robert Khoe & Marsha Tyszler: We feel that the external in-line control adds more features to the already versatile FS-X. We chose these options because we’ve had many requests for a volume control and a microphone.

    6. Frankenspiel Ltd. Creator on

      @ Giles Smith & Marsha Tyszler: You could choose to use any kind of 3rd party Y cable (this also applies to the 3.5mm analog cable which is included with every FS-X), since quality and specifications vary we can’t guarantee that every and any cable will work together with our external in-line control. We don't want to force people to buy our stuff, what we mean is that we can guarantee that our products will work together.

      @ Alex Zak: In the eventuality of us not making the stretch goal of £66.000 we might add it as an add-on.

    8. Frankenspiel Ltd. Creator on

      @ Kirill: Thanks! These are really interesting ideas, some we’re looking to do. For example your subwoofer idea. More than 2 speakers on a single channel however, right now, is a bit tricky with Bluetooth. FS-X is a modular concept, the basis of which is a single speaker and is meant to be used outdoors, in demanding situations, and a single case made of shock resistant neoprene makes sense. This way you can use and transport them seperately. There’s is no compulsion to buy this case, we simply offer it as a useful add-on. And if we reach our second stretch goal (£66.000) FS-X pair backers can get a free carrycase if they choose next to an external in-line control.

      @ nihal castelino: No problem! And yes, if at the end of the project we still exceed £46.000 in pledged funds, you will get your speaker equipped to resist dust and water to at least IPX4, and hopefully IPX5!

      Giles Smith gets +1! I'd like to know the answer to that.

      Also, if one were to plug in an in-line mic into each speaker (using two in-line mics), would it record sound in stereo? And would using the FS-X's internal mics also record in stereo if using both speakers at once?

      And +1 about the comment asking for an option to swap two in-lines for two cases. Some people may not need the in-line. I'm guessing that they must cost about the same amount if you're offering to swap 1-for-1. How about 2-for-2 swap? :-)

    11. Robert Khoe

      I'm with Lee and the others: option for two cases.

    12. Danny Dierickx on

      Me too with the +1 lee gibson, i'd also rather have 2 carrycases instead of the line in control. It's designed most importantly for Bluetooth use not line input.

    13. Laurence Freedman on

      @Lee, I'm with you on that one. The whole point of the Frankenspiel was that it has Bluetooth and is super portable, so I'd much rather have the cases and just control the volume with my iPhone.

      Nice stretch goal. You might want to add an option of 2 cases for anyone not wanting the inline controller.

    16. Laurence Freedman on

      @Krill why would you need a hole in the bag when the cases will already have loops built in that you could pair with a carabiner? Unless you meant for the line-in, in which case I get it, but it would also be pointless as the FS-Xs can already produce audio quality (using Bluetooth btw) that's comparable to line-in CD.

      Will one in line connector be able to used with a y cable to 'control' a pair of speakers?

    18. Alex Zak on

      Why don't you make the line-in controller available as an add on?

    19. Kirill on

      Nihal: The speaker has at lest ipx 4 of everything. they are striving for ipx5.

    20. Kirill on

      Im just going to throw this in here just in case. how about later in the future, have a cloud server that lets you hook up maybe 3 speakers for left, 3 for right and 2 for center (or any configuration you want(stack a few to make a speaker column)) perhaps later on release a dedicated sub that will connect with these.also because the speakers can be paired, wouldent it make sense to make a case that supports both of them? perhaps put holes in the bag so u can strap them to your backpack and play on the move or at least so I dont have to carry and buy 2 cases and carry them separately. then again i guess you could just ass velcro or something to make the cses attachable to each other.

      thanks for the awesome update, is the speaker waterproof or atleast usable in the bathroom exposed to steam with no issues :)
