Get better sound from your tube microphone with the MP1 Power Supply from Grimm Audio. Whether its a vintage or contemporary model, the MP1 will help you get the best possible sonic performance from your investment. The engineers at Grimm have leveraged their extensive experience designing the AD1 converter and CC1 master clock to ensure this boutique power supply takes your microphone to it's full potential.

Even if the power supply on your vintage microphone is still functioning, the MP1's stable power and exceptionally low noise floor can give you significantly improved sonic results; and voltage settings are customized at the factory for optimal performance with your microphone model. The unit offers discrete voltage regulators, a shunt regulator for the anode supply and a high precision series one for the filament supply. The anode supply offers a noise floor as low as -100 dBV, which, on average, is 20 dB better than existing supplies, while the shunt design turns the regulator into an active decoupling device, eliminating electrolytics.

The MP1 includes a detachable foot and multipin XLR cable that you can attach to your existing microphone cable.

• In many classic mics, the heater voltage is also used to bias the grid of the amplifying tube in the microphone, implicating an open gateway from the heater supply to the sensitive input of the mic’s amplifying stage. Grimm therefore chose to design a clean and ultralow-noise discrete voltage regulator for the heater supply as well. It features a very low drift to ensure the heater voltage always remains within specs.
• The MP1 features a specially designed discrete shunt high-voltage regulator fed from a current source to maximize suppression from mains-induced anomalies. It also offers very low noise (typically -96 dBV or 16 uV at 20 to 20,000 Hz unweighted). More importantly, this shunt supply sounds more natural than the more commonly used modern series regulators, due to the absence of electrolytic capacitors at the output.
• Both the high-voltage and the heater supplies have an extra crowbar protection circuit that will switch on in case one of the supplies breaks down. This is an extra line of defense to protect the valuable tube in your microphone.

Q: 1. Can this be used such as: mic - P1 - FetHead - recorder? I'm looking to boost a quiet mic more than the FetHead Phantom can, but then still supply phantom to a condenser mic.

A: If your recorder does not supply phantom power, the Xvive Audio P1 Portable Phantom Power Supply can help with your setup. The phantom power from this P1 power supply would pass through a Fethead Phantom, to your microphone which needs it. Please contact us at audio@bhphoto.com for more advice specific to the microphone you have, and the sounds you are trying to capture.

Q: 2. Does the D tap output also ACCEPT power via d-tap, thereby powering the ring? I ask because the gold mount plate doesn't work for many people, it's poorly designed to foul the gimbal or top handle when a 'normal' gold mount battery is attached. So I would like to know if i can attach a gold mount to the ring via a basic clamp mount (so not feeding power through pins, just a bog standard clamp), then make a male- male D-tap cable and plug INTO the power supply module's output from the battery's dtap output. IF that would work, it would make any other power supply modules on the ring 'hot' for accessories. Sorry for such a long question but i wanted to give the reason for it so you understand the dilemma. Please let me know? I have like 24 Gold mount batteries so i'm not excited to switch to Vlock system just for this bladdy gimbal

A: The Dtap connector on the Tilta Power Supply Module for Ring Grip will only output power.

Q: 3. hi, when using shotgun mic like MKE 600 or MKH 416 does it still need XLR cable to connect to P1 or you can just plug directly?

A: Plugging a microphone directly into an XLR input jack is never recommended. Remember that, by the principle of leverage, the force exerted on the connector will be proportional to the length of the mic. You can very quickly end up damaging the pins, or even the jack itself, and when phantom power is involved you also risk a short circuit if this happens. Always use a cable, even if it is a very short cable with low-profile connectors.

Q: 4. What is the input Amperage for these?

A: thank you for your question. This adapter runs 100 VAC to 240 VAC with an output voltage of 24V and current of 250MA

Q: 5. is this device can power 12t microphone?

A: The Xvive Audio P1 Portable Phantom Power Supply with Rechargeable Battery supplies 12 or 48V of phantom power, but does not supply 12V of T power. Although phantom power will not generally damage a T-powered microphone, they use different circuitry and T-power microphones cannot be properly used with phantom power supplies. A recommended T-power product can be found in the Denecke Dcode PS-T Microphone Power Supply (BH #DEPST): https://bhpho.to/3vd9fT2

Q: 6. Is this comparable with the Audix HT2 -Condenser Headworn Microphone?

A: This kit comes with the Audix HT2 condenser headworn microphone.

Q: 7. Will this work with the Core SWX Battery Plate for the Sony FX9?

A: Yes it should work well.

Q: 8. Is this a 110 ohm cable thatI can use for my GRIMM MU 1 AEB out to DAC/preamp ?

A: The Grimm Audio Stereo Pair of Audio Cables with XLR Connectors (6.56'), BH # GRSQM2X, is not impedance rated.

Q: 9. Can the Xvive P1 Phantom PS be connected to a TS mono mic level audio input using a XLR female to 3.5 TS mini jack cable?

A: Yes, you can use the Xvive Audio P1 Portable Phantom Power Supply to connect an XLR microphone that requires phantom power to a 3.5mm microphone input using an XLR female to 3.5mm TS male mini-jack cable.

Q: 10. Could I use this to power my Rode NTG1 and output to a XLR to 3.5mm adapter cable to input into a Canon 90D?

A: Yes, the Xvive Audio P1 Portable Phantom Power Supply with Rechargeable Battery can be used to provide phantom power to the Rode NTG1 Shotgun Microphone, and its output signal can be adapted for a 3.5mm input connection to a DSLR camera.
