MainStream Rear Panel Features

Introduction
The top panel of MainStream may be where all the magic happens, but nothing will happen if it can’t be powered up, and a mic, headphones, studio monitors, and other things aren’t connected to it, so let’s start there! Let’s take a look at each of these features, starting with the USB C power connector located near the bottom-left of MainStream, followed by a look at the input and output jacks, then working our way around.

Audio/Video Interface and Power Connector

• This 2×2 USB-C port is MainStream’s only source of power… but it does oh so much more than that! That said, we’ll start there. Simply connect one end of the included cable to this MainStream USB-C port and the other end to a computer’s USB-C port. If the computer is powered, then so is the MainStream.

NOTE: As seen on the silkscreen, this connector only accepts certified USB-C ≥3.1 cables.

• In addition to supplying the power to MainStream, this port also sends all audio, video, and data independently; this includes HDMI, USB, and analog inputs. This allows each video feed, audio source, and USB device to appear as its independent source (when plugged into a computer). As you’ll see later, there are also independent volume controls for each of these.

• This port delivers a resolution of 4Kp60 (Ultra HD). The maximum capture resolution is 1080p60 (Full HD) for the HDMI input. The USB audio format is 24 bits and 48 kHz.
  Additionally, this port receives a stereo audio signal from the computer and sends it to the headphones, monitors, and mix minus. The level is controlled via the PC audio return level control knob, located on the front of MainStream. [It’s the small one located in the upper-

• the left-hand side of MainStream; for reference, the silkscreen printed underneath the knob displays
  a computer.].

• Last, but not least, the USB-C port is also utilized for conducting firmware updates, function keys, and middleware.

• Please download the firmware updating software from the product page to make sure you have the latest.

• Don’t forget to change the input and output to ‘MainStream’ (or ‘MainStream HDMI’) via Settings.

XLR and 1/4″ Combo Input Jack [Channel 1]

This is a female XLR connector that accepts a mic or line-level input from almost any type of source. Professional ribbon, dynamic, and condenser mics all sound excellent through this input. The mic/line input will handle any kind of level you can toss at them, without overloading. The input level is controlled via the mic level control knob, located on the front of MainStream. [It’s the big one located on the left-hand side of MainStream; for reference, the silkscreen printed underneath the knob displays a microphone and headset.].

They are wired as follows, according to standards specified by the AES (Audio Engineering Society).

XLR Balanced Wiring:

• Pin 1 = Shield (ground)
• Pin 2 = Positive (+ or hot)
• Pin 3 = Negative (– or cold)

In addition to accepting a balanced mic signal using an XLR connector, this input channel may also accept a 1/4″ line-level signal driven by balanced or unbalanced sources. To connect balanced lines to this input, use a 1/4″ Tip- Ring-Sleeve (TRS) plug. “TRS” stands for Tip-Ring-Sleeve, the three connection points available on a stereo 1/4″ or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals and are wired as follows:

1/4″ TRS Balanced Mono Wiring

• Sleeve = Shield
• Tip = Hot (+)
• Ring = Cold (–)

To connect unbalanced lines to this input, use a 1/4″ mono (TS) phone plug, wired as follows:

1/4″ TS Unbalanced Mono Wiring

While channel 1 ties this combo jack and the 1/8″ TRRS jack above it, they will not work simultaneously. The XLR input takes precedence.

48V Phantom Power Switch

Most modern professional condenser mics require 48V phantom power which lets the mixer send low-current DC voltage to the mic’s electronics through the same wires that carry audio. (Semi-pro condenser mics often have batteries to accomplish  the same thing.) “Phantom” owes its name to an ability to be “unseen” by dynamic mics (Shure SM57/SM58, for instance), which don’t need external power and aren’t affected by it anyway. Press this switch if your microphone requires phantom power. (Always check the position of this switch before connecting microphones.).

• Never plug single-ended (unbalanced) microphones, or ribbon mics into the mic input jacks if phantom power is on. Do not plug instrument outputs into the mic XLR input jacks with phantom power on unless you know for certain it is safe to do so. Be sure that the mic level control is turned down (and/or the mic mute button is engaged) when connecting a microphone to the mic input when phantom power is turned on to prevent pops from getting through to the speakers.

1/8″ Headset Jack [Channel 1]

This is a female 1/8″ TRRS connector that accepts a line-level signal from a gaming headset. It is a mono mic-level input and a stereo output of the headphone mix. The input level is controlled via the mic level control knob, located on the front of MainStream. [It’s the big one locatedon the left-hand side of MainStream; for reference, the silkscreen printed underneath the knob displays a microphone and headset.]. The output level is controlled via the headphones level control knob, located on the front of MainStream. [It’s the big one located on the right-hand side of MainStream; for reference, the silkscreen printed underneath the knob displays a set of headphones.].

• Warning: The headset amp is loud and could cause permanent hearing damage. Even intermediate levels may be painfully loud with some headsets. BE CAREFUL! Always turn the volume knob all the way down before connecting headsets. Then turn it up slowly as you listen carefully.
• While channel 1’s XLR mic supports 48V phantom power, this 1/8″ mic/headset does not. However, this jack does add an extra +5V of “plug-in power”.
• While channel 1 ties this 1/8″ TRRS jack and the combo jack below it, they will not work simultaneously. The XLR input takes precedence.

Direct Monitor Switch
Engage this switch to monitor the input signals. The input signals will then be routed to the headphones and monitors. The input monitoring occurs in the analog domain, resulting in zero-latency. If you want to hear your processed voice coming back through the PC return from the computer, then make sure that this switch is disengaged. Note that there may be some audible latency.

1/8″ Smartphone Stereo Jack [Channel 2]

• Connect a smartphone or tablet to this jack using a 1/8″ TRRS connector. Remote guests can interact in real time with no echo or loopback due to the built-in Mix-Minus feature.
• This jack is always at full max. The volume is adjusted via the device, not the controls on MainStream.  However, the signal may be muted via the mute button.
• This jack also accepts a 1/8″ TRS connector. However, with TRRS, the signal may be sent and received;  goes both ways! The signal that’s returned to the smartphone is the mix-minus (so there’s no echo or loopback for the guest).

1/4″ Phones Jack

This 1/4″ TRS connector supplies the output to stereo headphones (or a headphone amplifier). The volume is controlled via the headphones knob on the top panel. The phones output follows standard conventions:

• Tip = Left channel
• Ring = Right channel
• Sleeve = Ground

WARNING: The headphone amp is loud and can cause permanent hearing damage. Even intermediate levels may be painfully loud with some headphones. BE CAREFUL! Always turn the phones level control all the way down before connecting headphones, or doing anything new that may affect the headphone volume. Then turn it up slowly as you listen carefully.

1/4″ Monitor Out L/R Jacks

These 1/4″ balanced stereo output jacks connect to the input of powered monitors. The signal at this output is a stereo mix of all inputs. This includes channel 1 unless the direct monitor switch is disengaged. The output level is controlled via the monitor output level knob, located on the front of MainStream. [It’s the small one located on the right-hand sideof MainStream; for reference, the silkscreen printed underneath the knob displays a set of monitors.]. It shouldn’t come as any surprise that we would highly recommend any sized MR Series or CR-X / CR-XBT monitors.  Check the Mackie website for more information!

HDMI Input Jack

Connect one end of an HDMI cable to this jack and the other end to an audio/video device. This could be a video game console, computer, DSLR camera, etc. The input level is controlled via the HDMI audio level control knob, located on the front of MainStream. [It’s the small one located ionthe lower- left-hand side of MainStream; for reference, the silkscreen printed underneath the knob displays an HDMI jack.].  The HDMI Type A 2.0 input jack accepts (up to) Category 3 HDMI cable types, delivering a resolution of 4Kp60 (Ultra HD). The maximum capture resolution is 1080p60 (Full HD). The HDMI audio inputs are 224 bitsand 48 kHz.

HDMI Passthrough Jack

This HDMI passthrough jack outputs the incoming HDMI input to a computer monitor or TV for low latency and full resolution (up to 4K60). It is perfect for gaming in real-time with max resolution. Connect one end of an HDMI cable to this jack and the other end to a television or computer monitor’s HDMI input. Doing so sends the feed from the HDMI  input to the connected output device TV/monitorr).  The HDMI Type A 2.0 passthrough jack accepts (up to) Category 3 HDMI cable types, delivering a resolution of 4Kp60  (Ultra HD). The maximum capture resolution is 1080p60 (Full HD). The HDMI passthrough audio outputs are 24 bits and 48 kHz.

Dual USB-C Input Hub

These dual USB-C inputs essentially act as a USB hub. They are used for sending and receiving audio, video, and data to a computer. This could be any number of things such as a webcam, USB mic, flash drive, DSLR camera, or just about any other USB-C source.  These inputs are then sent through to the USB-C output (located just to the left of these inputs; and because this connector is also used to power up MainStream, a cable should already be connected to the USB-C output.).  These inputs will appear as independent devices on the receiving computer.

• Be sure to use the correct cable for your device. The right input accepts high-quality webcams, mics, and other USB-C devices. High-quality devices (above 3.0) plugged into the left input do not work as well.
• These USB-C connections are for inputs only. They are not a source of power.

Firmware Updates
The USB-C (power) connector is also utilized for conducting firmware updates.  Please download the firmware updating software from the product page to make sure you have the latest.

Mainstream Top Panel Features

Introduction
From top to bottom and left to right, each MainStream is outfitted with a bunch of knobs, buttons, LEDs, and more. So much more, that we will call out and describe each one, starting near the upper-left corner with the PC audio return level control knob.

PC Audio Return Level Control Knob

This knob is used to adjust the input volume of the audio return from the computer to the headphones, monitors, and mix minus.  For the proper setting, we suggest rotating this knob fully clockwise, its max level. Then turn it down if needed. It ranges from (off) to maximum gain (max).

Mic Level Control Knob (+Sig/OL LED)

This knob is used to adjust the channel 1 volume – microphone and headset – to the headphones and mix minus.

It ranges from

• XLR/TRS input – ∞ (off) to maximum gain (+60 dBu)
• 1/8″ TRRS headset input – ∞ (off) to maximum gain (+50 dBu)

The accompanying dual-colored LED will illuminate green when the channel 1 (mic / headset) signal is present, indicating signal. It will remain lit so long as there is signal above –20 dBu present in that channel. This dual- colored LED will illuminate red when the channel 1 (mic/headset) signal is too high, indicating a signal overload. This should be avoided, as distortion will occur. If the OL LED comes on regularly, check that the volume knob is set correctly for the mic/headset. The signal is at –3 dB before the hard clip begins. The LED is measured post-level knob, but pre-output level knob.

Aux Mute Button Mute switches do just what they sound like they do. They turn off the signal by “routing” it into oblivion. Pressing this button mutes the channel 2 (1/8″ aux) input. Engaging the aux mute button (almost) provides the same results as turning the device’s volume down.  Mute buttons illuminate red when engaged.

Mic Mute Button

Mute switches do just what they sound like they do. They turn off the signal by “routing” it into oblivion. Pressing this button mutes the channel 1 (mic/headset) input. Engaging the mic mute button (almost) provides the same results as turning the mic level control knob down. Mute buttons illuminate red when engaged (as seen to the left).

Headphone Level Control Knob

This knob is used to adjust the volume at the 1/4″ headphones and 1/8″ headset outputs from (off) to maximum gain (max). Make sure that this knob is fully off before selecting or adding a new source.

WARNING: The headphone amp is loud and can cause permanent hearing damage. Even intermediate levels may be painfully loud with some headphones. BE CAREFUL! Always turn the phone’s level control all the way down before connecting headphones, or doing anything new that may affect the headphone volume. Then turn it up slowly as you listen carefully.

Monitor Level Control Knob

This knob controls the output volume for the monitors with the level ranging from a low of (off, far-left) to maximum gain (max, far-right). The signal at this output is a stereo mix of all inputs. This includes channel 1 unless the direct monitor switch is disengaged.

HDMI Audio Mute Button

Mute switches do just what they sound like they do. They turn off the signal by “routing” it into oblivion. Pressing this button mutes the HDMI audio that is sent to the headphones, monitors, and mix minus. Engaging the HDMI audio mute button (almost) provides the same results as turning the HDMI audio level control knob down. Mute buttons illuminate red when engaged (as seen to the left).

Headphone/Monitor Mute Button

Mute switches do just what they sound like they do. They turn off the signal by “routing” it into oblivion. Pressing this button mutes the headphone and monitor outputs that are sent to the 1/4″ headphone output, 1/8″ headset output, and 1/4″ monitor outputs. Engaging the headphone/monitor mute button (almost) provides the same results as turning the headphone and monitor level control knobs down. Mute buttons illuminate red when engaged.

HDMI Audio Level Control Knob

This knob is used to adjust the input volume of the HDMI audio to the headphones, monitors, and mix-minus outputs. For the proper setting, we suggest rotating this knob fully clockwise, its max level. Then turn it down if needed.  It ranges from (off) to maximum gain (max).

Main Meters

The output meter displays the output signal level, presented in stereo. This meter should remain green with the occasional bump into the yellow zone. If the meters remain constantly yellow (or there’s any red clipping), lower the output until it’s gone and check the input levels, as well.

• Red [clipping] = Overload (OL)
• Yellow = +4 dBu to +15 dBu
• Green [bottom] = –30 dBu to +3 dBu

The output meters reflect the audio signal of the headphone’s post-headphone output level knob.

Multifunction Keys

These six multifunction keys (aka F1-F6) have a dual purpose. For starters, they are programmable and may be assigned tasks of your choosing, such as scene switching, triggering virtual sample pads, and more. These multifunction keys may be mapped by accessing the hotkey settings in any application, including OBS. They mimic and “borrow” the same functionality as any PC or Mac’s function keys (F1-F6), then act as the “triggers” to whatever function they are mapped to. When tapped, that key’s LED will illuminate brighter to indicate that the assigned function is triggered. These multifunction keys also double as cheat codes for gamers out there. All games may be “cracked” by pressing and holding down two keys simultaneously for two seconds before releasing. Hold and release the square and circle keys first, followed immediately by holding and releasing the triangle and Running Man keys.  The game that is currently being played will confirm that you are now playing in “cheat” mode. If there are multiple “cheats” available, then youcano scroll through and select one by running a finger up and down the main meters. Releasing your finger makes the selection.

• This function only works if the user has set up the main meters to read their fingerprint. Otherwise, it will not work.
