Stereo Audio preamplifiers

Compact, affordable, and capable of a stunningly wide range of tones, the BlueTube DP V2 dual-path mic/instrument preamplifier offers two independent channels, each with an XMAX Class A solid-state preamp, followed in the signal path by a 12AX7 vacuum-tube stage.

The EZ-MPA1 is a microphone preamplifier with front-panel volume control and audio level metering. A front-panel switch engages an audio compressor to control overloads and clipping during high level audio bursts or peaks from the microphone.

The EZ-MPA2 is a stereo microphone preamplifier with front-panel volume controls and audio level metering. A front-panel switch engages audio compressors to control overloads and clipping during high level audio bursts or peaks from the microphones.

The EZ-PH1 is a stereo phono preamplifier with front-panel volume trimmers and audio level metering. Stereo RCA jacks and a grounding screw are provided on the rear panel for connecting a turntable tone arm.

The FP-MP1 is the ideal choice in most applications requiring a preamp. RDL's exclusive low-noise discrete circuitry produces studio quality low noise performance in an economical preamplifier.

The HR-MP2 is a dual channel microphone preamplifier with line-level outputs. Each section provides identical rear-panel signal connections and front-panel controls.

The HR-MP2A is a dual channel microphone preamplifier with line-level outputs. Each section provides identical rear-panel signal connections and front-panel controls.

The RU-MLA2 is a dual channel audio preamplifier. The inputs and outputs may be connected through the front-panel XLR jacks or on the rear panel detachable terminal blocks. Each input accepts either a balanced microphone or line level signal.

The RU-MLA2T is the same RU-MLA2 with a studio-quality audio output transformer. The RU-MLA2 is a dual channel audio preamplifier. The inputs and outputs may be connected through the front-panel XLR jacks or on the rear panel detachable terminal bloc

The ST-GSP1 is a gated speech preamplifier designed to be used in a variety of situations where it is desired to produce an automatically switched line-level signal from a microphone.

The ST-PH1 is a stereophonic phono preamplifier. Each of the two channel circuits is identical. The ST-PH1 has standard 47 kΩ impedance unbalanced phono cartridge inputs. Equalization follows the RIAA curve. Each output is capable of driving balanced

The STM-1 is a low-cost quality microphone preamplifier designed for use in commercial sound and broadcast applications. The compact size makes it ideal where a larger or heavier preamp cannot be used.

The STM-2 is a quality low-noise microphone preamplifier designed for use in commercial sound, broadcast, and recording. The STM-2 is very flexible, with gain adjustment from 35 to 65 dB, two balanced or unbalanced outputs, and available phantom supp

The STM-2X is the ideal choice in many installations where a microphone preamplifier is required, and is the ideal choice where either a toggle-type switch or push-to-talk switch is to be provided for microphone control, particularly if condenser mic

The STM-3 is a quality low-noise microphone preamplifier designed for use in surveillance, commercial sound, broadcast, and recording where higher than normal gain is required. The STM-3 is very flexible, with gain adjustment from 45 to 75 dB, two ba

The STM-LDA3 is designed for use in quality commercial sound, broadcast and recording applications. The 1.2 kΩ balanced input accepts a wide variety of microphone input levels without loading professional low-impedance microphones. A multi-turn gain

We named this channel strip the Studio Channel, and indeed it’s a wonderful studio tool. But it’s great for live performance, too. Featuring tube preamplification, a VCA-based compressor, and three-band EQ, it delivers a huge variety of timbres.

Compact and affordable, the ever-popular TubePre V2 professional tube preamplifier employs our popular XMAX Class A solid-state preamp, followed in the signal path by a 12AX7 vacuum-tube stage.
