About the LCT 1040

The LCT 1040 is a microphone system with a comprehensive set of options to dial in the perfect sound – from your sweet spot.
It all started with the vision of creating a studio microphone that allows you to easily adapt the sound you need for your session without switching to another microphone.
After ten years of development and with help from the international audio community, the LCT 1040 brings new levels to your production workflow. You’ll be more efficient and sound better than ever before.
The LCT 1040 is a studio condenser microphone using both, FET and tube circuitry. It is exclusively built from premium components and features four distinct all-analog tube characteristics.
Together with the blendable FET circuit, they allow you to effortlessly find the perfect sound for your session.

Gold-sputtered 1″ true condenser capsule
100% analog signal path
Four distinct all-analog tube characteristics: Clear, Warm, Dark, Saturated
Independent FET circuit with dedicated XLR output
Both circuits can be seamlessly blended
Tube and FET microphone in one housing
Remote control and power supply unit
Low-cut filters and pre-attenuation settings
Seamless polar pattern control
Default/Reverse switch to freely determine the front of the microphone
LED status indicators

Settings and indicators

Tube
Change the tube characteristic.

Clear: Tube works at technical optimum.
Warm: Smooth and pleasant high-end.
Dark: Tamed highs for bright sources.
Saturated: Rich harmonics and subtle compression.

Filter
Set the low-cut filter to fit your needs.

Attenuation
Set the right attenuation for your recording situation.

Circuit
Blend between tube and FET circuit. This ratio will be sent to the Mix output.

Pattern
Set your polar patterns seamlessly. The notches indicate standard polar patterns.

Default / Reverse
Define which side is set as the front of the microphone. Default indicates the tube window is set as the front. Reverse sets the logo as the front.

Connectors

Preparing the microphone for recording

Mount the shock mount onto a stable microphone stand. Open the fixture of the shock mount. Put the tube microphone in the shock mount. The tube window indicates the default front. Lock the fixture.

Attach the pop filter from below. You will feel when the magnet snaps it into place.
Connect the microphone to the PSU via the 10-pin cable. Flip the power switch on the PSU. Check the status LEDs and wait until ‘Operational’ stops blinking.
Now, the microphone system has reached its full sensitivity and you are ready to record.

Stacked remote setup

The LCT 1040 consists of three parts: the microphone, the PSU, and the remote. The remote is attached to the PSU by default (no cable needed).
Connect the microphone via the 10-pin cable.
On the right side, you can see how to wire all parts for the stacked remote setup.

Detached remote setup
You can detach the remote from the PSU and use it without any drawbacks in sound quality. This is perfect when you have a separate control and recording room. The connection works via standard XLR cable and is compatible with your patchbay (maximum cable length is 150m / 492ft).
If transformers are in the signal path, the communication between the remote and PSU will not work. Polarity inversion however is not a problem.
If you use a half-normalled patch bay, make sure to insert a cable in the patch-point in the row below. Otherwise the remote will not receive the necessary operating voltage.
Tip: If you are not certain if the remote is properly connected, check the ‘Remote’ LED on the PSU.

Connect the microphone to the PSU via the 10-pin cable. Connect the PSU to the remote via standard XLR cable.
Turn on power and check all status LEDs.

FAQs

When is the system fully operational?
The ‘Operational’ LED on the remote indicates that the system is ready to use. Once it stops blinking, the microphone has reached full sensitivity.
Can I damage something when incorrectly patched?
The PSU sends +24V to the remote, which could possibly damage other equipment. So please be careful when patching the remote signal.
Can I damage the system if cables are unplugged while it’s powered?
Technically, no. For the sake of treating your LCT 1040 well, please refrain from doing it.
Do I need to hang the mic upside down due to the heat coming from the tube?
We tested it. There is no audible difference. Just position it the way you prefer.
Can I extend the cable between the remote and the PSU by combining multiple cables?
Yes, but please make sure they’re not longer than 150m / 492ft.
Are you using some kind of ‘modeling’ for the tube characteristics?
The signals stay purely in the analog domain. Only the controls are digital, which gives you the best of both worlds.
What kind of tube is inside?
After months of testing, we settled on the E88CC / 6DJ8.
Can I change the tube?
The LCT 1040 is an extremely fine-tuned and calibrated system. We spent months finding the perfect tube. So, no, please don’t change the tube. You’ll also void your warranty by doing so.

Please note

The capsule is a sensitive, high precision component. Make sure you do not drop the microphone from high heights and avoid strong mechanical stress and force.
To ensure high sensitivity and the best sound reproduction possible, avoid exposing it to moisture, dust or extreme temperatures.
Do not apply excessive force on the buttons or the connected cables.
When disconnecting the microphone cable, grasp the connector instead of pulling the cable.
Do not attempt to modify or open the product, as doing so will void your product warranty.
The casing of the LCT 1040 can be cleaned easily using a wet cloth, never use alcohol or another solvent for cleaning.

Important Notice!
Only use C13 power cord connected to a socket-outlet with earthing connection. Do not use any ground lifting circuits. In case of problems with electrical hum and interference, first try to change position, install a mains filter, or try a different power outlet. If the problem persists please contact our support. Removing the earthing connection can have lethal consequences. Only use indoors, in safe and dry environments. There are no user-serviceable parts inside the power supply unit or the microphone, but there are potentially lethal voltages. If it does not work correctly, please consult your dealer. Do not open the unit yourself. Do not use with damaged cables or after unit has fallen and loose parts or broken glass can be heard inside. Do not cover the power supply unit, always leave enough space around it for proper ventilation.
