It gives a DUAL OPERATION (function) for your mixer – you can select between diverse transformer amps, giving a large playground for DIFFERENT SOUND COLOR CHARACTER of your mixes – see Youtube video…

Input Channel (L/R) – convert to Mono – switch

Hard Pan L/R input to CENTER SWITCH – for monos like Kick Bass Snare Vocal…

Mono switch = extra stable real analog mono base for your mix (eg. kick and bass) – then a superior separation, 3D depth for stereo instruments – like on large-format analog recording consoles

Benefits:

Save precious analog channels
True Analog Mono – center placed in the stereo pan field
1 Mono = 1CH – instead to waste stereo – 2 analog L/R for a mono like Kick

1 x Switch or 2 x Switch

Benefits:

Mono switch = save analog channels from DAW
Sending from DAW to SUMMING 2 mono instruments (2 channels), instead of 2 x stereo (4 ch’s)
Mono switch makes center placed real analog mono like on big analog consoles, true analog mono.

You can choose switch type:

1 x Switch per channel

By this feature you can convert “SEPARATELY” choosing L or R input (Hard Panned Left / OR / Hard Panned Right) input signals to become center placed – or leave hard panned L / or / R (see benefits and example below in blue)

1 x switch per 2 channel (channel pair L/R or 1/2)

This feature converts L/R inputs “COMBINED” (two hard panned L/R Input) signals to absolute center placed Mono signal. (1 x Stereo to 2 Mono)

(mono) SNARE on channel 1Left,
(mono) KICK on channel 2Right

Customer question: if the panel is not too “crowded” I’d go for 1 sw per channel otherwise 1 sw per 2 channel is fine. They have the same functionality?

Answer: Almost similar. By the 1 sw per channel you can use the “hard pan” feature.
Lets see a 4 input channel setup, each input tracks are mono instruments.

Example 1
1L Input = KICK = Switch (UP) = CENTER
2R Input = Right Overhead = Switch (DOWN) = HARD PAN RIGHT
3L Input = Left Overhead = Switch (DOWN) = HARD PAN LEFT
4R Input = BASS = Switch (UP) = CENTER

Example 2
1L Input = Shaker = Switch (DOWN) = HARD PAN LEFT
2R Input = Vocal or Bass = Switch (UP) = CENTER
3L Input = Snare or Kick = Switch (UP) = CENTER
4R Input = Tambourine = Switch (DOWN) = HARD PAN RIGHT

However, for mono signals (such as kick, snares, lead vocals or bass that should appear in the middle of a mix), it would be a waste to use Stereo L/R panned channels what would amount to two (2) required converters for a mono result.

For example, channel pairs 1L & 2R switched to mono (ST1 stereo to 1/2) both instruments become placed in the center of the panorama.

Routing from DAW to Sum

DAW Mono Snare: —-Left side of stereo out— (interface Ch 1 Left out)—- sum Left 1IN
DAW Mono Kick:—-Right side of stereo out (interface Ch 2 Right out)—–sum Right 2IN
Then switch to mono mode to place Snare and Kick in the center of panorama.

youtube video demo

Please note!

Panning for instruments in the DAW sequencer (Steinberg cubase, pro tools, flstudio, reaper, logic pro, Ableton etc.) should place the kick hard left, the bass hard on the right, and so on.

* with STM(Stereo to mono)option can save a lot of DAW interface out

** no need to waste precious stereo CH’s for mono instruments

***clarity of position in the stereo field (mono is true mono)

Assign mono tracks from the DAW that you’d like to have in the middle of your mix (perhaps bass and and kick or lead vocals) to channels
1-2 or 7-8 and then engage the MONO buttons to bring those channels to the center of the mix. Mono sounds more powerful
assigned on the VM Summing than using mono in your DAW.
and you save precious stereo CH’s for mono instruments.

With mono signals one should switch these to mono mode to combine them to single D/A converter, thereby avoiding the waste of having to use a D/A pair for one mono track.

Passive Summing Gain Reduction

Maintaining the passive summing box within the working range of your DAW interface is essential because it ensures optimal sound quality SNR and adequate headroom.
