MixSwitch-C Front Panel Overview
MixSwitch-C Rear Panel Overview
MixSwitch-C Functional Description
MixSwitch-C can be thought of as a high-quality, 4-channel A-B Switch. Four “A” Inputs and four “B” Inputs are
either switched or combined into four Outputs. A1 is switched or combined into Output-1, A2 into Output-2, A3
into Output-3, and A4 into Output-4. Inputs B1 through B4 are likewise steered to Output-1 through Output-4.
A front-panel mode-switch determines whether the A and B Inputs are selected individually (Switch) or mixed
together (Sum). 4 LEDs indicate the desired Mode (A Input Only; B Input Only, Sum A+B, External Control). Inputs
are routed to their respective Outputs at Unity Gain. When A and B are both selected, they are mixed together
equally, both at unity gain. The gain-staging of the MixSwitch provides the headroom needed for this function.
Basic Features
A front panel switching function of the MixSwitch-C is controlled by a single 3 position switch:
Fully Counter Clockwise: Input A Only
Center Position: Input A + Input B (Summed)
Fully Clockwise: Input B Only
The Center Position Mode (Input A + Input B) is useful to combine the outputs of 2 consoles (up to 4 of the Outputs
from each console) to create a “bigger” console; each set of Input signals is summed at unity.
If more than 4 Outputs need to be combined (Auxes or Subgroups from 2 consoles), then additional MixSwitch-C
units can be connected to and controlled by a MixSwitch or MixSwitch-C Master using a DSub-9 cable. When
connected, the secondary unit selection switch will be overridden by the master unit with a Red LED indicated that
the unit is being controlled remotely. When connected, only control signals are sent from the Master unit
(MixSwitch or MixSwitch-C). The individual audio Ins and Outs remain isolated to each MixSwitch or MixSwitch-C.
Main Inputs: Rear Panel Connectors
There are two sets of 4 input jacks: Inputs A1 through A4 and Inputs B1 through B4.
The jacks are Latching, 3-Pin Female XLR.
Pin-2 is in-polarity, Pin-3 is out-of-polarity, Pin-1 is connected directly to the chassis metalwork.
Electronically Balanced.
Maximum Input Level: +24dBu
Input Impedance: >20KΩ (Differential)
Inputs are labeled 1 through 4, but 1 also indicates (L), and 2 also indicates (R ). This L-R labeling is for convenience
only, these signals can come from any source.
Main Outputs: Rear Panel Connectors
There is one set of 4 output jacks: Outputs 1-4
The jacks are Latching, 3-Pin Male XLR.
Pin-2 driven +, Pin-3 driven -, Pin-1 is connected directly to the chassis metalwork.
Electronically Balanced Output.
Maximum Output Level: +28dBu into 600 Ω or higher
Output Impedance: 50Ω
Outputs are labeled 1 through 4, but 1 also indicates (L), and 2 also indicates (R ). This L-R labeling is for
convenience only, these signals can go to any destination.
Remote Connectors (DSub-9 Input and Output):
The DSub-9 connectors allow the MixSwitch or MixSwitch-C Master to control any added MixSwitch-C unit to act
as an expander. Units are fitted with In & Out DSub-9 connectors (Male & Female) to allow this control function to
daisy- chain to additional units when connected.
DSub-9 connections: MixSwitch and MixSwitch-C DSub-9 Connector Pin# Function (Some pins shown below are not
currently used on MixSwitch-C, but all wiring between Male and Female connectors should be connected):
1: 0-Volts (Internally tied to Chassis with 10Ω resistor)
2: Solo Audio – (Balanced signal for Listen Audio)
3: Solo DC Control
4: Select A (Tied to 0-Volts when active)
5: Mute Command (Tied to 0-Volts when active)
6: Solo Audio + (Balanced signal for Listen Audio)
7: 0-Volts (Internally tied to Chassis with 10Ω resistor)
8: Power OK (Tied to 0-Volts when active)
9: Select B (Tied to 0-Volts when active)

APB-DynaSonics' MixSwitch-C is a versatile, multi-channel audio switching and combining system that occupies only
1U of rack space. It is a simplified Contractor version of APBs proven MiSitch that is so often used in concert
applications. Typical applications include selecting between the Primary console and Backup or secondary consoles, or
between Headline and Opening Act consoles in concert/presentation situations. MixSwitch-C also allows for the
simultaneous use of both consoles (A+B equally mixed). In demanding club applications, selection between FOH and DJ
miers into a common audio sstem can easil be performed solving the long found dilemma of hos equipment is fed
directly into the sound system. Each MixSwitch-C unit can control 2 channels of 4 line-level audio signals; Additional
units can be added to jointly control additional line level channels such as switching between a pair of consoles with
LCR+Sub outputs plus 8 Matrix Channels which would take three MixSwitch units with the first acting as a master and
the 2nd two units acting as the expander providing switching of 12 Channel outputs of two consoles. MixSwitch-C is also
used as an expander to the full function MixSwitch.
Another application of MixSwitch-C is to use a pair of these devices with a standard MixSwitch to select between
additional console sources. A MixSwitch-C is plugged into input A and a MixSwitch-C plugged into input B of a master
MixSwitch. This allows easy switching between 4 Consoles in a festival or multiple console performance situation while
maintaining full talk and music playback inputs as well as an additional 2 Channel input by way of the master MixSwitch
device.
FEATURE OVERVIEW:
Provides ability to easily switch between a primary and a backup console.
Select between headline and opening act consoles in concert/presentation situations or operate both
consoles simultaneously in A+B mode.
Allows easily selection between FOH and DJ mixers in club applications.
Units may be linked in a master-expander fashion to control additional multiples of blocks of 4 line level input
channels to an equal number of output channels.
4 Consoles may be switch when three MixSwitch or MixSwitch-C devices are used together.
Connectors for remote switching.
Linking system of MixSwitch-C compatible with standard MixSwitch units.
