Model 4010 "The Restoration Preamp"^TM
This preamp was especially designed for listening to and restoring mono recordings. It features a full range of Turnover frequencies and Rolloff attenuations easily selected by front panel rotary switches. It also has five selectable Rumble Filter frequencies and eleven output Lowpass Filter frequencies. It has very low output noise and hum -- the built-in power supply is as quiet as battery operation.

Model 402 Mains-powered Low-Noise Microphone Preamp
This preamp was especially designed to drive a computer sound card's line-input. The noise floor is nearly 70 dB below the line-in max signal level at 60 dB gain. You can, of course, use it for any application where a low-noise mic preamp is needed. The cast aluminum enclosure minimizes pickup of unwanted interference. The performance of the 402 is virtually identical to the 401, and the price is the same -- so take your choice.

Model 4041 Stereo RIAA Phono Preamp
(for moving coil and moving magnet cartridges
This is a rack mount version of our popular model 404A. It too was especially designed to drive a computer sound card's line-input for restoring vinyl LP records which were recorded using RIAA equalization. However, it's also excellent for just listening to the music! This preamp has very low output noise and very low power line hum pickup, two features essential to creating a CD-quality wave file. The internal rechargeable batteries provide complete isolation from the power mains, however operation from the power mains is also switch selectable.

Model 408 Mains Operated Stereo Phono Preamp
This preamp was especially designed to drive a computer sound card's line-input for restoring 33-1/3, 45 and 78 RPM records which were recorded using various equalizations. This preamp has very low output noise and very low power line hum pickup, two features essential to creating a CD-quality wave file. The cast aluminum enclosure minimizes pickup of unwanted interference.

Model 409 Mains-Powered Stereo RIAA Phono Preamp
This preamp was especially designed to drive a computer sound card's line-input for restoring vinyl LP records which were recorded using RIAA equalization. This preamp has very low output noise and very low power line hum pickup, two features essential to creating a CD-quality wave file. The cast aluminum enclosure minimizes pickup of unwanted interference.

Model 411 Measurement Microphone Preamplifier
This preamp was especially designed for sound measurements and to inter-compare microphones. It supplies +5 V phantom to unbalance mics and +48 V phantom to balanced mics. Its noise floor is very low so it has a wide dynamic range. Operation is from a 24 VDC wall power supply.

Model 432 Two-Channel Microphone Preamp with Phantom Power
High performance, low-noise line-operated preamp in a cast aluminum case. Built-in 5 volt phantom power for use with our 816 and 817 series electrect condenser mics or a wide variety of dynamic mics. Internal jumpers enable/disable phantom power to either or both inputs.

Model 444A Stereo Headphone Amplifier
This is a high-quality headphone amplifier featuring a non-inverting output, wide bandwidth, low noise, an excellent loudness control and DC operated balance and volume. The cast aluminum enclosure minimizes the pickup of unwanted signals.

Model 465 6-Channel Volume Controller
A high quality control featuring an all-analog circuit, both balanced and unbalanced inputs and outputs, master volume control, individual channel volume controls, a mute function and IR remote control.

Model 603A Tuneable Stereo Rumble Filter
This tunable high-pass filter is useful anytime you have low frequency noise that needs to be eliminated. For example, low frequencies on the record itself or because of record warp or other physical problem.

Model 817A Electret Condenser Microphone
The 817 has the same performance as the model 816 but it uses a smaller cartridge and comes in a smaller diameter package: a 0.313 inch diameter tube instead of a 0.5 inch diameter.

Model 818 Electret Condenser Microphone
The 818 has a higher frequency response and a greater sensitivity than the 817A. The tube diameter is the same (0,313 inch) but the tube is longer (7.5 inches) and the price is a bit higher.

Model SMS-1 Sound Measurement SYstem
Consists of a model 411 Microphone Preamp and a model 818 Measurement Microphone. Optionally, you can add a Behringer ECM-8000 Measurement Microphone (with cable) and/or a Dayton EMM-6 Measurement Microphone (with cable).
The price for all SMS-1 versions is 10% less than the cost of the item purchases separately.
