Frequently Asked Questions - RP-1 ART

How do I connect the RP-1 receiver to my speakers?

Connect your speakers to the banana plug outputs on the rear panel. Ensure the impedance matches (4-8 ohms recommended).

Can I use the RP-1 with a turntable?

Yes, if your turntable has a built-in phono preamp or you connect an external one. The RP-1 does not have a dedicated phono input.

What is the maximum power output per channel?

The RP-1 delivers approximately 50W per channel at 8 ohms, 20 Hz - 20 kHz, with 0.1% THD.

How do I reset the RP-1?

Unplug the unit for 10 seconds, then plug it back in. If issues persist, contact ART support.

Does the RP-1 support Bluetooth?

No, the RP-1 does not have built-in Bluetooth. Use an external Bluetooth receiver connected via RCA or optical input.

What is the warranty period?

ART provides a 2-year limited warranty for the RP-1. Keep your purchase receipt.

Why is there no sound coming from my speakers?

Check that the RP-1 is powered on, the correct input is selected, and the volume is turned up. Verify speaker connections and that the mute function is off.

Can I use headphones and speakers simultaneously?

No, the headphone output disables the speaker outputs when plugged in. Unplug headphones to use speakers.

How do I clean the RP-1?

Use a soft, dry cloth to wipe the exterior. Do not use any liquids or abrasive cleaners.

Where can I find the user manual?

The user manual is available for free download at notice-facile.com or on ART's official website.

INTRODUCTION

Thank you for purchasing Applied Research and Technology's RP-1. The RP-1 is the ideal solution to increasing the performance of your ribbon and dynamic microphones. This phantom powered preamp brings out all of the nuances of your mic before running into your recording interface or Mixer through long cable runs.

With the RP1 you can tailor the loading on the mic through the variable impedance control. The low cut filter allows you to remove wind noise and plosives before adding additional gain.

The discrete preamp circuitry inside is designed for low noise and transparent operation. The balanced output drives long cable runs with ease allowing you to place the preamp as close as possible to the mic before picking up any noise or interference.

The RP-1 is packaged in a rugged extrusion, metal XLR jacks and a solid rubber foot underneath for long, reliable operation.

Get the very best out of your mics with the RP-1

FEATURES

• Very low noise mic preamp
- Switchable Low Cut Filter
• Variable Impedance control
- Adds at least 20dB of gain to your mic
- Low THD discrete circuitry
- Runs off a Phantom power supply
- Able to drive long balanced cables
- Compact rugged package, extruded chassis
- Designed and developed in the USA

INSTALLATION and OPERATION

Connect the outputs of the RP-1 to a Phantom powered source such as a mixer or preamplifier.

Connect the RP-1 input to your Ribbon or dynamic mic.

Make sure you start with the gain pot set to their minimum setting. Once connected engage the Phantom power and adjust the gain on the RP-1 for the desired level. The phantom power will not pass through to the input thus avoiding any potential damage to any dynamic or ribbon mic.

APPLICATIONS

Perfect for: Live use, Project studios, Home and Commercial installations.

The RP-1 may be used in a wide variety of applications and environments. Self-contained in an extruded enclosure, the remote mic Preamp is designed for continuous professional use. Because the unit is compact and lightweight, mounting location is not critical.

The RP-1 is placed inline with the Mic. The RP-1 can be zip tied to the mic stand, so tonal adjustments can be made on the fly.

LOW CUT FILTER control

The Low Cut Filter is a single tuned High Pass Filter. The input signal can be filtered to remove low frequency information. The roll off frequency is set at 100Hz. Since it is single tuned, it preserves some low frequency content so its use is less obtrusive. It is especially useful in close mic'd applications cutting out pops and wind noise.

Variable Impedance Function

Using this variable impedance function allows the user to adjust the input impedance seen by the microphone, in turn achieving better tonal response from your microphone used.

Dynamic Mic

Dynamic (coil) microphones are sensitive to loading. If these mics are not coupled correctly, the result maybe a loss in frequency response and could result in added distortion.

As an example a common mic like the SM57 prefers a 600ohm load. When the load is varied above or below the 600ohms, then the mid range resonance could sound harsh and distorted. The low-end response will also sound more controlled with a 600ohm load. There are many dynamic mics that may have similar issues but not be as sensitive to loading as the SM57.

Ribbon Mic

Ribbon type (transformer coupled) microphones are sensitive to the input impedance of the preamps or mixers used to achieve the optimum frequency response. A Ribbon mic would like to see an input impedance several times larger than its output impedance. Ribbon mics, being transformer coupled, have increased impedance at high and low frequencies. On the low end the mic is power bound, as you load it there becomes a low frequency cut off at higher levels, so it may sound distorted. At the high end, the output impedance of the transformer increases (independent of level), so the greater the load the less high end.

As an example, a typical ribbon mic with a characteristic impedance of 300ohms may have an inherent 600ohm impedance at 20kHz and a 2k impedance at its low frequency resonance (about 50Hz). If you set the input impedance to 10k ohms your result would be a 0.25dB drop at 20kHz. This would also drop the low frequency resonance by 1.3dB. Compare this to a typical mixer input (3k input impedance) where you would get a 0.75dB drop at 20kHz and 3.6dB at resonance.

So increasing the input impedance seen by the mic using the impedance pots on the Dual RP will result in an optimum performance from the ribbon mic used. If the preamp or mixer input impedance is too low then you will start to limit the frequency response of the ribbon mic. When this occurs, the low-end of the microphone's sound quality will be limited and the transient response will sound flat degrading the overall performance of the microphone. So by adjusting the impedance pot on the Dual RP, you can achieve a clean full frequency response from your microphones using the Dual RP.

The beauty of the RP-1 may be the ability to operate at higher impedance or control the impedance vs. the mixer you are currently using.
