A NOTE TO CUSTOMERS WHO WANT TO PURCHASE ADD-ON EQUALIZERS

In the past, most manufacturers of preamp-control centers, integrated amplifiers, and receivers made it easy to connect external audio equalizers and similar devices.  They almost universally included a RECORDER  MONITOR LOOP.  These were easily identifiable by a MONITOR button on the front panel.  Others even included and EXTERNAL EQUALIZER LOOP.  These were easily identifiable by two pair of extra RCA jacks on the rear panel, usually with jumper connections between them.  You inserted your external device into these connection.  If you have such a product, you will have little problem connecting any of our external products.

If you are in the market for a new preamp-control center, integrated amplifier, or receiver, you should keep that in mind.  There really is a need for this feature if you use an audio recorder or an external equalizer.  It facilitates your being able to ensure that the audio recording you were making was actually taking place as you intended, as you can monitor its progress.

More recent A/V products have removed these feature at a savings of about $0.50 cost.  If this is your case, not all is lost.  There are work-arounds such as   the use of a separate phono stage, like any of our REK-O-KUT preamps below.  Connect your turntable to the separate phono stage and then connect the preamp output to the add-on device (SNR, Dehisser, or Re-Equalizer, etc.) and the add-on output to an unused AUX input on your receiver/amplifier.  In that case, you would not use the phono imput of your main amplifier.  You would play phono records thru the AUX input.

A NOTE TO CUSTOMERS ABOUT OUR PREAMPLIFIERS

If you want a good preamplifier for you hifi system any of ours will give you the performance of very good built-jn preamp, often better. 

If you want to play only LPs and 45s, and/or live outside of the USA, you might focus on MKIV,  which has a very flat frequency response, good overload protection, low noise and an inline world power supply - no wall wart.

If you want to play LPs, 45s and also 78s, but have a modest system and speakers and don't mind wall transformers, the MKII preamp will do well.

If you have two turntables, one for LPs & 45s, and another for 78s, and want one switch to change both the turntable and sound EQ at the same time,  the MKII will probably interest you a lot more.   Non-USA customers will need the accessory 220 VAC wall transformer.

If you have one or two turntables, one for LPs & 45s, and another for 78s, and want exceptional fidelity and accurate  performance with LPs, 45, and both US and European/Asian 78s, the UTLRA is a what you will want.  It is our best.

NEW! - REK-O-KUT
®  RE-EQUALIZER III

 NO WALL TRANSFORMER - NO VOLTAGE SWITCH - IN LINE  UNIVERSAL POWER ADAPTER

 PERFECT MONO FROM STEREO PICKUP

 VERTICAL / LATERAL PLAY SWITCH

 GROOVE WALL CHOICE


"the REQ3 ... an absolute joy to use; thank you so much for producing it...at such a reasonable price point"

 "from Japan: I cannot imagine playing...records without a RE-EQUALIZER III anymore. I love it!"

from Holland: "I’m very much impressed after listening a few of my favorite 78’s with the re-equalizer!"

"The ability to plug in any cartridge and switch between vertical or lateral is an especially nice feature"

"fantastic!  Thank you so much for producing it!"

from Russia: " I am completely satisfied with it"

Pre-1955 records were recorded to different standard than now employed in RIAA equalized phono amplifiers.  The Re-Equalizer compensates for this.  Easily installed thru the external tape monitor loop of your preamplifier/receiver, or between preamplifer and main amplifier.

With the REQ III you can blend left and right channels for perfect true mono, or listen to left or right using a stereo pickup.  Flip the Vertical/Lateral switch and you can listen to Edison, OKEY or Pathe' discs.  It has no bulky wall power adapter that eats outlet space, but an in-line automatic unit that requires no power switch, i.e., no mistakes.  Use outside of the USA is easy. Outside of USA, either use a plug adapter or obtain a common power cord locally.

                         SEE INSTRUCTIONS

A precise, two-way selector switch utilizing RCA connectors,  and designed especially for phono applications. Because most other switches are designed only for high-level, or "Aux" levels, they introduce hum and other noises when used with the extremely low levels produced by phono cartridges.

This selector can be used to connect  either of two phono turntables to a hifi amplifier phono input. It can also be used to add two Aux inputs to an amplifier that has only one such input and it can be used wherever one input needs to be expanded to two or visa-versa.

REK-O-KUT®  PROFESSIONAL MOVING MAGNET PREAMP MKIV

*ACCURATE FREQUENCY RESPONSE, LOW- DISTORTION-LOW NOISE-NEW HIGH OUTPUT*

* NOW WITH WORLD POWER SUPPLY *

"I’m glad I discovered your products as it’s made a big difference to my hobby!"
"My setup now has a more full sound with a top and bottom that was missing"
"Your preamp easily blows away the phono stage on the Marantz" 

Add a turntable to an amplifier that has no phono input or a second turntable to an amplifier with only one phono input.  The REK-O-KUT Professional Moving Magnet Preamp can be used to convert any AUX input to phono use.  The Professional Moving Magnet Preamp is designed for both home as well as broadcast and studio applications.

The REK-O-KUT Professional Moving Magnet Preamp can be used with a line level input on any amplifier or  mixing console for playback of turntables equipped with a conventional, magnetic phono cartridge.  Typical input sensitivities of such inputs are roughly 250 mVolts, and the outputs of typical moving magnet cartridges is  about 3.5 mVolts. The preamp boosts the level of the magnetic cartridge and also applies "record compensation" in the  form of the RIAA curve. This adjusts the relative levels of bass and treble to match that of modern records.  Used with the REK-O-KUT Re-Equalizer, it makes a fully adjustable playback system for vintage and mono records.

Use it anywhere.  With its in-line  world power supply (as opposed to wall transformer) all that is needed is that you obtain either a USA to your country plug adapter, or obtain a common, local plug-in line cord.

*Highly accurate RIAA record compensation.
*Includes 39 inch 43 pF/ft interconnect cable.
*Input matched to most high-quality pickups.
*6 Hz subsonic filter to cut ultra low rumble.
*In-line power supply, no wall transformer.

REK-O-KUT®  ULTRA PREAMP

OUR MOST ACCURATE PREAMPLIFIER EVER - FITS ALL PURPOSES

for audiophiles, 78 collectors, archivists


* RULER-FLAT RESPONSE

* VERY LOW DISTORTION

* OVERLOAD RESISTANT

* 2 TURNTABLE
INPUTS

* US / EURO / ASIA 78 EQ

* FLAT EQ FOR SOFTWARE
 

*NOW WITH IN-LINE WORLD POWER SUPPLY - NO WALL WART, NO SWITCH*

Even if you do not play vintage records, the ULTRA beats almost all built-in phono stages and is an excellent upgrade.  Add one or two turntables to an amplifier that has no phono input or a second turntable to an amplifier with only one phono input.   The ULTRA Preamp can connect to the line level input on any amplifier, computer sound card or mixing console for playback of turntables equipped with a magnetic phono cartridge.

For RIAA LPs it is extremely accurate to within +/- 1/8 dB.  It can apply accurate compensation for USA, European, Asian or other foreign 78s with front panel switches.  A 300 Hz position means accurate play of pre 1935 records as well as later US Columbia and many European and Asian 78s.  It a can also accurately play London/Decca FFRR and similar vintage LPs, and many non-NAB broadcast transcriptions.  If you want to use computer software for record compensation, it has a totally flat setting.

Because of its extremely accurate RIAA compensation, it is an excellent companion to the REK-O-KUT Re-Equalizer, resulting in a fully adjustable playback system for vintage and mono records.

With its in-line world power supply (as opposed to an outlet stealing, wall transformer) it can be used anyplace; no switches to set.  All that is required is either a EURO plug adapter, or a common, IEC-C7, figure-8 line cord for your country's power outlet.

REK-O-KUT®  AUDIOPHILE ARCHIVAL PREAMP MKII

Now with higher output and overload capability, and an added power on/off switch.  Add one or two turntables to an amplifier that has no phono input or a second turntable to an amplifier with only one phono input.  The REK-O-KUT Audiophile Archival Preamp can be used to convert any AUX input to phono use.  A Rear panel switch sets up for one turntable for LP and one for 78s, or one turntable for both types of record.  If desired, connect the output of the preamp directly to a computer sound card. It is designed for both home as well as broadcast and studio applications. 

The preamp also applies accurate “record compensation” in the form of the RIAA curve or the most common 78 RPM record curve.  Actually, this 78 curve is almost a perfect match for early London/Decca FFRR, and many non-NAB broadcast transcriptions.  This equalization curve is adjustable with the front panel Equalization switch. This adjusts the relative levels of bass and treble to match that of modern records or of vintage 78s and early radio broadcast transcriptions.

from Japan: "I... thought that the Audiophile Archival Preamp MKII was the greatest...of this kind"

"Thank you for making these preamps affordable"
