Introduction
City Theatrical’s 5905 Multiverse
®
Studio Receiver 2.4GHz brings the advanced features of
the Multiverse wireless DMX/RDM system to the film and video world, where fast setup
and reliability are key objectives. The weather resistant Multiverse Studio Receiver
contains a long-life lithium-ion polymer battery giving 20 hours of use. The Multiverse
Studio Receiver has a full four button user interface with a backlit LED display that makes
setup easy and gives feedback on system performance.
The 5905 Multiverse Studio Receiver contains a 2.4GHz radio, and allows the user to
select which single universe to receive, and which radio band to use via the Multiverse
SHoW ID.
The DMX corded connector allows the Multiverse Studio Receiver and external antenna
to hang below the lighting fixture, giving improved data fidelity.
5905 Multiverse Studio Receiver Features
•2.4GHz Broadcast Radio
Transmit and receive on the 2.4GHz band.
•Long Life Rechargeable Battery
20 hour battery life with default settings
•Rugged and Splashproof
The IP61 rated plastic case makes it splashproof and rainproof (but not for
permanent outdoor use).
•User Selectable SHoW IDs
City Theatrical has always produced wireless DMX products that allow the user to
select the optimum transmission method. Users may select full bandwidth hopping,
hopping limited to a section of the spectrum (including areas of the spectrum
outside of the Wi-Fi range), or adaptive hopping.
•mDMX (Multiverse SHoW IDs only)
mDMX is a form of DMX optimized for wireless broadcast that dramatically reduces
data being broadcast, thereby reducing unneeded radio energy.
•mRDM (Multiverse SHoW IDs only)
Multiverse is able to broadcast RDM information without disrupting the DMX
broadcast. This feature is not available even in wired RDM systems.
•SHoW Key Security (Multiverse SHoW IDs only)
SHoW Key is an additional three-digit code that can be added to the Multiverse
SHoW ID that will prevent any other system set on the same SHoW ID from
interfering with your system.
•Forward Error Correction (Multiverse SHoW IDs only)
Allows the Receiver to detect and correct errors that may occur in the wireless
transmission of data.
•Ultra Low Latency
Total average system latency of 4ms.
•Adaptive Spread Spectrum Frequency Hopping
Adaptive Spread Spectrum Frequency Hopping identifies and masks off hopping
channels that contain interference, replacing them in the hop sequence with

Page 5 of 12
alternate channels.
•Adjustable Output Power
Sometimes an application calls for the most available broadcast power, but many
entertainment systems can utilize lower output power to reduce detrimental effects
on other radio systems in the venue, reduce reflections, and improve performance.
• Protocols supported: ANSI E1.11 DMX512-A; E1.20 RDM
• Compatible with all Multiverse and SHoW DMX Neo products
• User can select a single universe to receive
• A very simple user interface to set SHoW ID, universe, and other features
• RDM proxy and responder functions
• Firmware updateable via USB port
• USB-Power Adaptor and USB-A to USB-C cable included
• Selectable display timeout and brightness level
• Selectable Auto Off Timeout
• Battery Time Remaining displayed in both hours/minutes and percent
• Contactless charging
Installation
Multiverse Studio Receiver can either be powered with its internal battery, or with 5VDC power
into its USB-C connector from its included external power supply (100-240VAC in, 5VDC out)
or from another external power supply (such as a lighting fixture) providing 5VDC. Turn the
Receiver on or off by pushing and holding the Power/Enter button.
User Interface Screen
Upon power up, the Multiverse Studio Receiver displays the SHoW ID, universe, radio signal
quality, and DMX connection status. Pressing the “Up” or “Down” button will take you to the
universe selection screen. Pressing “Enter” will select SHoW ID or universe for editing and will
commit the change when done.
Pressing the “Menu” button will take you to the Menu screen. Holding the Menu button will
cancel the current edit. See page 7 for a full explanation of Menu items.
SHoW ID

It is recommended that users perform a site survey using City Theatrical’s RadioScan™
Spectrum Analyzer before choosing a SHoW ID, to insure optimum radio performance.
Use the default SHoW ID, or choose a SHoW ID and enter that SHoW ID into the user
interface of your Multiverse transmitter (Multiverse SHoW Baby, Multiverse Node, or
Multiverse Transmitter) and all receivers. The SHoW ID and universe number (and SHoW
Key, if used) must match on your transmitter and all receivers.
Multiverse Studio is backwards compatible with SHoW DMX Neo products when using SHoW
DMX Neo SHoW IDs. See Table 6 on page 12 for a list of SHoW DMX Neo SHoW IDs.
Here is further explanation of the Multiverse SHoW ID numbering system:

channels.
2 Use only mid band
channels (availablefor
Data Rate 1 only).
3 Use only highband
channels.
4 Use only extreme high
band to avoid WiFi
(2.4GHz only).
5 Adaptive hopping.
Avoids busy channels
by analyzing
spectrum.
If multiple wireless
systems need to operate
with the same data rate
and band this value will
change the hopping
pattern to minimize
overlapping between the
two systems. Can be any
number from 0 –9 (not all
bands have all Hop
Patterns).
Note: Not all combinations of digits are possible and unused numbers are reserved for future
use.
Universe
Default universe is 1.
When the Multiverse Studio Receiver is a receiver in a multi universe system with a Multiverse
Transmitter you can select the universe the Multiverse Studio Receiver will receive and output.
The selected universe must match a valid universe being transmitted.
Note: If universe selected is not being broadcast by the transmitter, the universe number will
be shown in a color opposite of the background color on the user interface to alert you to the
incorrect selection.

Signal Quality Bars
The signal quality bars give a visualization of signal quality as seen at the Receiver. Four bars
is excellent signal quality, three bars is good signal quality, two bars is marginal, and one bar
is low.
DMX
When no DMX is present “NO DMX” is displayed in red type, and “DMX” is displayed in black
type when DMX is present. These colors can vary if colored backgrounds are selected.
Battery
Battery life remaining is shown in both percentage, and in hours and minutes remaining.
SHoW ID/Universe
If the SHoW ID is displayed prominently, the universe is displayed in smaller type at the
bottom of the screen, and vice versa.
Menu Screen
Pressing the “Menu” button takes you to the Menu screen.
•Power
Output power may be user selected as Low, Med, Hi, or Max. It is a best practice to
use the least amount of output power to achieve a successful broadcast. This helps
to reduce reflections which can reduce signal fidelity and to reduce any potential
negative effect on other radio users in the area. You can monitor signal strength
via RDM. Default is Maximum.
•Antenna
If a panel (P/N 5981) or Yagi (P/N 5982) antenna is used instead of the default
omni antenna, choose it on this menu for optimum performance and to remain in
compliance with FCC and other radio compliance regulations. An (P/N 5638)
adapter cable is required to use a panel or Yagi antenna.
•SHoW Key (Multiverse SHoW IDs only)
The SHoW Key setting allows a user to enter a key to privatize their SHoW ID from
another system on the same SHoW ID. SHoW IDs and SHoW Keys need to match
in order for receivers and transmitters to talk to each other. Keeping your SHoW
Key private will provide a level of security to your Multiverse system from
unauthorized use. The range is 0 (Default) to 500.
Table 2: SHoW IDs and SHoW Keys
•Display Color
The background color of the display can be changed from white to magenta, cyan,
green, yellow, or red. Default is white.
•RDM Traffic
The RDM Traffic setting determines whether RDM data is passed downstream of
the Multiverse Studio Receiver. It does not affect whether the Multiverse Studio
Receiver is detectable by devices upstream. Default is On.

•Auto Off Time
Auto Off allows the user to set a time to turn off the Multiverse Studio if no radio
signal is detected from a Multiverse Transmitter while battery power is being used.
Settings are 30 minutes to 10 hours, or off. Default is 8h 00m. Whenever a radio
signal is received, or when the user presses a button, the time counter begins
again.
•Backlight Time
The Backlight Timeout setting determines how long the LCD backlight will remain
on after the last button press. The timeout can be set to off (backlight will never
timeout) or any interval from 10 seconds to 30 minutes. Default is off. After a
screen timeout, pushing any button will wake up the screen without changing the
screen selection.
•Backlight Level
Controls Backlight brightness. Range is 25%-100%. Default is 70%, which allows
20 hour battery life. 100% brightness allows 16 hours battery life.
•Lock Screen
The user interface screen can be locked to prevent accidental or malicious
changes, while leaving the SHoW ID/Universe display visible. To unlock the
screen, use a long press on the menu button.
•Factory Defaults
Resets all settings to factory defaults.
