LECTROSONICS SRC, SRC5P Camera Slot Dual UHF Receiver
Product Information
The Lectrosonics Camera Slot Dual UHF Receiver (model SRC SRC5P) is a high- performance wireless audio receiver designed for professional use. It features a proprietary algorithm that encodes digital audio information into an analog format, allowing for robust transmission over an analog FM wireless link. The receiver incorporates state-of-the-art filters, RF amplifiers, mixers, and detectors to capture the encoded signal, while a DSP (Digital Signal Processor) recovers the original digital audio. This digital/analog hybrid technique offers several advantages. The digitally encoded information provides superior noise immunity compared to traditional compandor-based systems. The analog transmission format ensures efficient spectrum and power usage, as well as an extended operating range. Even under weak RF conditions, the received signal degrades gracefully, delivering usable audio at maximum range. Additionally, the absence of compandor artifacts reduces pumping and breathing problems.
The receiver comes with a backlit LCD screen that displays RF and audio levels, transmitter battery status, pilot tone status, and diversity activity for both receivers. It also features front panel controls, including a menu/select button, power/back button, up and down buttons, and an IR sync port for quick setup with compatible transmitters.

Digital Hybrid Wireless
The Lectrosonics Digital Hybrid Wireless® uses innovative technology to combine the advantages of digital audio with the advantages of analog RF transmission. The result delivers the superior sound quality of a digital system and the excellent range of an analog system. A proprietary algorithm encodes the digital audio information into an analog format which can be transmitted in a robust manner over an analog FM wireless link. The receiver employs state-of-the-art filters, RF amplifiers, mixers, and detectors to capture the encoded signal and a DSP recovers the original digital audio. This digital/analog hybrid technique has some very beneficial properties. Because the information being transmitted is digitally encoded, immunity to noise is much higher than what a compandor can offer. Because the encoded audio is sent in analog format, spectral and power efficiency and operating range are not compromised. weak RF conditions, the received signal degrades gracefully, like an analog system, delivering as much usable audio as possible at maximum range. Since the audio is free of compandor artifacts, pumping, and breathing problems are also greatly reduced.
Quick Start Summary
The following checklist includes the minimum required settings to start using
the receiver.
- Install either a battery sled or camera slot adapter kit (see pages 5-6).
- Connect power to the receiver (see pages 6-7).
- Set the DIVMODE for single or dual-channel operation (see pages 8-9).
- Set the COMPAT (compatibility) mode for the transmitters to be used (see pages 8-9).
- Find clear operating frequencies for one or both receivers (see page 10).
- Set transmitters on the matching frequencies (see transmitter manual).
- Verify transmitters are set to the same compatibility mode as the receiver (see transmitter manual).
- Adjust transmitter input gain to match voice level and mic position (see transmitter manual).
- Adjust the receiver output level as needed for the camera or mixer input level desired (see pages 8-9).
IMPORTANT : Performance will be degraded if Receiver 2 is set 4.2 to 4.8 MHz higher than Receiver 1. The LCD will also flash this message periodically.
Front Panel Controls and Functions
Audio Outputs
In addition to the audio outputs on the rear panel, the front panel of the
receiver provides a second set of outputs through a 5-pin connector. This
allows both audio channels to be connected through external cables for cameras
with only one audio channel enabled in the slot. The TA5M connector provides
two balanced outputs with the following pinouts:
- Pin 1 Pin 2 Pin 3 Pin 4 Pin 5
- Shields CH1 + CH1 – CH2 + CH2 –
LCD Screen
A backlit, graphics-type LCD is used to set up and monitor the receiver. The
Main Window shown above is used during normal operation, to display RF and
audio levels, transmitter battery status, pilot tone status an diversity
activity for both receivers.
MENU/SEL Button
This button is used to select menu items and enter setup screens during setup.
IR (Infrared) Sync
An IR Sync Port is used for quick setup with transmitters that offer this
feature. Settings for frequency, step size, compatibility mode, and talkback
are transferred from the receiver to the transmitter via the IR ports.
NOTE: Selected compatibility mode and talk back will only sync if they
are available options on the transmitter you are syncing with.
PWR/BACK Button
Press the PWR/BACK switch to turn the power on. Press and hold it until the
display goes blank to turn the power off. It also functions as a “back” button
while navigating the various menus and setup screens to return to the previous
screen or menu item. The firmware “remembers” whether the receiver was turned
on or off after power is disconnected, and it returns to that state when power
is restored. This allows the receiver to power up and down as the camera or
external supply is turned on and off. Press the PWR/BACK button from the Main
Window to briefly display the external power voltage.
UP/DOWN Arrow Buttons
The UP and DOWN arrow buttons are used to select various options and adjust
values in the setup screens, and provide secondary functions such as locking
out the panel to guard against accidental changes.
Installing Rear Panel Adapters
Installation of the rear panel output/power adapters is the same for all models.
Battery Adapters
Battery sled adapters configure the receiver for standalone use or to provide
battery backup power. Several options are available:
- SRBATTSLEDTOP
- SRBATTSLEDBOTTOM
- SR9VBP (inserts into the SLED adapters)
Battery Adapters
Battery sled adapters configure the receiver for standalone use or to provide
battery backup power. Several options are available:
- SRBATTSLEDTOP
- SRBATTSLEDBOTTOM
- SR9VBP (inserts into the SLED adapters)
The battery sled adapters do not include charging circuitry. Batteries must be charged with their respective chargers. The adapters include an integral circuit that automatically selects between the battery and the external source, whichever delivers the highest voltage.
External Power Supply
DCR12/A5U AC power supply with interchangeable blades/posts for use in Europe,
the UK, Australia, and the USA; 100-240 V, 50/60 Hz input; 12 VDC (regulated),
0.3 A max. output, 6.0 W. Sold separately.
Main Window (LCD)
The Main Window displays information concerning the condition of the Pilot
Tone, antenna phase, RF and audio signal levels, and battery conditions for
both the receiver and the associated transmitter.
NOTE: When the RATIO DIVERSITY mode is selected, both receivers are
combined to pick up the same transmitter, so the Main A window will display a
single audio channel. Pressing the MENU/SEL button accesses the menus and
screens for setting up the receiver and searching for clear frequency
channels.
Navigating the LCD
Note : Press the BACK button from the Main Window to briefly display the
external power supply voltage.
Accessing Block 606
NOTE: Block 606 is ONLY AVAILABLE in Bands B1 and C1 Available from any
setup screen that displays the two receiver selection options next to each
other, press and hold the DOWN arrow and simultaneously press PWR/BACK. Using
the DOWN arrow, toggle between B1/C1 and Block 606.
COMPACT
Compatibility modes adjust the FM deviation and audio processing (companding)
to match other Lectrosonics models and some models from other manufacturers.
Using SmartTuneTM
SmartTune is the easiest and fastest way to scan the local RF spectrum and
find clear operating frequencies.
NOTE: 23N and B1N (“N” refers to North America) scans skip past TV Channel 37 (608 to 614 MHz) since it is reserved for radio astronomy in North America.
After the scanning is complete, the newly discovered frequency will be set automatically. The LCD will then prompt to SYNC the frequency to the matching transmitter via the IR port (DOWN ARROW), or to continue by pressing OK (MENU/SEL). After leaving the SYNC screen, the LCD will ask about setting up the other receiver. Use the UP and DOWN arrows to select YES to tune the other receiver, then press MENU/SEL to continue. Turn on the transmitter that matches the first receiver that was tuned. Use the UP and DOWN arrows to select YES and press MENU/SEL. After the scanning is complete, the newly discovered frequency will be set automatically. The LCD will then prompt to SYNC the frequency to the matching transmitter via the IR port (DOWN ARROW), or to continue by pressing OK (MENU/SEL). Press the BACK button several times to return to the Main Screen and verify that both transmitters show a strong RF signal strength and that the Pilot Tone icons are NOT blinking.
Manual Scanning
Scan Window
First, turn off all of the transmitters you intend to use with the receiver.
Navigate to the SETUP/SCAN screen and press the MENU/SEL button to start the
scanner. The display will switch to the Scan Window (see illustration above)
and start scanning immediately. Allow the receiver to scan across the entire
tuning range at least once, then press the MENU/SEL button to stop the
scanning. Scroll through the screen with the UP and DOWN buttons and find a
frequency where no (or very weak) RF signals are present. Press the PWR/BACK
button to set the receiver to this new frequency. Press both the UP and DOWN
buttons at the same time to switch to the Zoom View Window (see illustration
above). In this view, the cursor remains fixed in the center of the screen,
and the background scrolls behind it. The frequency can be stepped up and down
in 100 kHz increments using the UP and DOWN arrow buttons.
When the receiver is configured for SWITCHED diversity (dual chan- nel mode), two cursors will appear when the scanning is stopped. Press MENU/SEL to toggle between the two receivers. The cursor for the selected receiver will be a dashed rather than a solid line. Select each receiver and use the UP and DOWN buttons to locate a frequency with no (or very weak) RF activity. Keep the frequencies of the two receivers at least 700 kHz apart to minimize de-sensing (short-range) issues. This spacing is a “worst case” approximation assuming the transmitters are about 25 feet from the receiver antennas. Data gathered during a scan is stored until it is intentionally erased or the power is turned off. Previous data will remain and subsequent scans can be made to search for additional signals or to accumulate higher peaks. To clear the scan memory and screens, press the back button several times to return to the Main Window, then press and hold the PWR/BACK button briefly. As soon as Powering off… appears on the display, release the button. The receiver will remain turned on, and the scan data will be erased.
