Telos One, Talkshoe and Skype …

V SchRecently I had to opportunity to work with my good friend Victor Cajiao, host and producer of the Typical Mac User Podcast. Victor has upgraded his studio configuration, and he asked for some assistance. We both agreed that it would be a good idea to share our experience with the community.

The first stage of the project was an exchange of emails with Victor specifying his new gear and specific intentions in terms of production scenarios.


• Create a Skype Mix Minus

• Create a Telos One Mix Minus

• Incorporate an external Cart Insert option

• Incorporate support for a future external Voice Processor

• Support recording to an external device

Our goal was to support three workflows: common Skype sessions, common Host/Telco sessions, and complex Studio Broadcast/Podcast sessions with external Talkshoe participation patched in by way of the Telos One. I went to work and designed a configuration diagram in order to simplify implemntation.

Please refer to the following notes:

General Configuration:

Stereo line output from the Cart machine feeds a set of Line inputs on the console using a 3.5″ stereo male to RCA left and right male cable. 3.5″ to 1/4″ male adapters are required.

Stereo Line Output from the main [MacPro] system feeds a set of Line Inputs on the console suing a 3.5′ stereo male to RCA left and right male cable. 3.5″ to 1/4″ male adapters are required.

Console Aux send 1 feeds the main Telos One Input.

Main Telos One Output feeds a single Line Input on the console.

Console Aux Send 2 feeds the MacPro Line Input using a 1/4″ to 3.5′ cable/adapter.

Console Main-Mix feeds external recorder Inputs.

Aux Buses:

Aux Bus Send 1 routes the Studio Mic, Skype participants, and Cart instances to the Telco participants. Notice that this Send is off on the Telco channel on the console. This alleviates sending the caller’s audio back to the hybrid.

Aux Bus Send 2 routes the Studio Mic, the Telco participants, and the Cart instances to the MacPro. Notice that this Send is off on the Skype channel on the console. This alleviates sending the Skype participant’s audio back to the MacPro that is in fact running Skype.

Keep in mind that the Aux Send Masters need to be set accordingly.

External Processing Support:

A standard insert cable will provide easy implementation of a voice processor on the Studio Mic channel.


Considering that all channels are routed through the console, the main-mix can be recorded by feeding supported console outputs to an external recorder.

    Hi Paul, do you have a similar diagram and setup to this but without the Telos? Basically to do Skype, with a Mackie Onyx 1220 with FireWire, MacBook Pro, Samson Compressor, and Zoom H4 recorder? Thank you sir! Your site is awesome!

    Hi Dennis,

    Thank you sir! Your site is awesome!

    I’m glad that you are finding the site helpful. 😉

    It sounds like the only somewhat complex issue that you are dealing with is the Firewire/Skype requirement. My notes may be a bit out of date on this: to the best of my knowledge, Skype still has problems with Firewire support …

    If you can verify basic Skype/Firewire compatibility, we can then talk about setting up your mix-minus.

    Hi Paul, I have been recording my podcasts with Skype, FireWire through the Onyx 1220, and HiJack Pro. That all has been working but I think if I utilize the mix-minus (and Samson Compressor/De-esser/Limiter) that I would get a better result. Thanks again.

    Hijack Pro is essentially creating the mix-minus for you within the application itself. In this case there is no need to change this.

    You can process your voice externally with your compressor before it hits the recording software. There are a few things to keep in mind.

    The firewire output on the Mackie is pre inset, pre-eq, and pre-fader. This means that the independent tracks sent out via firewire will not be affected by the integrated processor.

    However the “main-mix” firewire output is, and will be affected by the incorporated processor. Make sure that you keep this in mind when you set things up in Hijack Pro.

    In terms of processor integration, all that is needed is a standard insert cable that is designed to place a serial processor [like a compressor] “in-line” on a channel, with full intention of providing a fully processed signal.

    So, the single end of the insert cable gets connected to the insert jack on your mic channel on the mixer. The “tip” end gets connected to the input on your compressor, and the “ring” end gets connected to the output on your compressor. This will send your mic signal out through the processor and it will be returned to the mixer.

    You should be all set. By the way, in the future, let’s post these inquires on the forum instead of in the blog post comment’s area. This will make the information more accessible to others who may need similar assistance.

    Let me know how it goes …

    Great write up Paul. Of course the end of the story is that this set up is working very well and the outcome can be heard during my live show on on Sundays at 5PM PST. The Typical Mac User Podcast Live show.

    Thanks to Paul for all he does for the community and for working with me towards my end goal.

    Thanks my friend

    Thanks Paul for the explanation! Keep up the great work!

    You are welcome my friend …


    Glad to help, and thanks as well.

    I have my setup a little different but with similar results. The main difference is that we patch skypecast callers into the overall bridge connection with talkshoe. Thus I am able to have all of the skypecast callers and bridge callers hear each other. It is not perfect as I have to have a strict microphone discpline becasue when we get a 100 or more people on a call 50 on Skype and 50 or so on the bridge everyone but the speakers have to be muted and we open mic people as needed.

    In order to make the bridging work I have a couple of devices I use to make sure line leveling remains across two computers and two mixers.

    The whole idea of the configuration is to support conversation between the Skype callers, the Talkshoe callers, and the Host. It’s not just a simple connection diagram. The mix minus buses are created by using the Aux Buses on the mixer.

    The Skype output form the main computer feeds a channel on the board. Aux Bus 1 on that channel routes Skype to the hybrid input [to Talkshoe participants].

    The Hybrid output [Talkshoe participants] feeds a channel on the board. Aux bus 2 on that channel routes Talkshoe to the input on the main computer. Skype can hear and converse with Talkshoe.

    You have no idea how helpful this is. I’ve been trying to get a good reference for this for two years. radio producers have given me the snub when they hear i run a podcast and fellow podcasters seem so insecure they are reluctant to share any ideas on their setups or offer advice.

    so thank you so much….

    You’re welcome 😉

    I can relate to what you are saying. In fact, I’m comfortable with my knowledge of this subject matter. On the other hand – I have a secret passion – learning how to develop useful applications.

    The development community at large is not as helpful as I would have anticipated, and it frustrates the heck out of me.

    My point is – I know how it feels, and you will not experience a lack of support here because I’m happy to help.
