Luxman CL-1000 Tube Preamplifier
At LUXMAN, we consider a technology "advanced" only if it enhances your ability to enjoy music. This principle finds its highest expression in the CL-1000, the new flagship of our tube preamplifiers.
The CL-1000 is the successor to the classic C-1000, released in 1975, and is a perfect match for the exclusive MQ-300 tube power amplifier. Both reflect LUXMAN's unparalleled expertise in tube technology. In the 1960s, when the audio industry was rapidly adopting transistor amplifiers, LUXMAN recognized the indescribable beauty of music reproduction with tubes. And we have continued to build tube components without interruption.
The CL-1000 is a tribute to the past, yet it also embodies the best of today with a major leap forward in sonic clarity: the transformer-based volume control we call LECUTA (Luxman Electronically Controlled Ultimate Transformer Attenuator). Furthermore, super-permalloy core output transformers contribute to a vibrant soundstage. The cabinet is clad in natural walnut with a rosewood gloss finish, adding a touch of warmth and refinement. All in all, the CL-1000 harmoniously blends advanced technology with musical sophistication.
Introduction of the transformer-coupled attenuator LECUTA:
The heart of any preamplifier is the volume control. If not executed correctly, this crucial circuit element can lead to imbalances between the left and right channels at low volumes, resulting in subtle but noticeable distortion. That's why LUXMAN developed our acclaimed LECUA attenuator system. Now we've refined the concept with LECUTA, the electronically controlled Luxman Ultimate Transformer Attenuator.
The volume control on the front panel is actually a 34-position rotary switch that triggers 34 relays located completely outside the signal path. These relays activate 34 taps on the corresponding left and right transformers. These taps are what adjust the volume in carefully calibrated increments. Because transformer cores can affect sound quality, we chose FINEMET® core material from Hitachi Metals, Ltd. This material features a unique nanocrystal structure for high saturation flux density, high relative permeability, and low core loss. This ensures you enjoy a rich, detailed, and uncompromising sound, even at low volumes.
Safety instructions
Electronic devices:
1. General Use: • Electronic devices are designed for use in enclosed, dry rooms only. Direct sunlight, moisture, and extreme temperatures may impair function. • Avoid proximity to water sources or other liquids. 2. Electrical Safety: • Use only with the specified power source (e.g., 220-240 V AC). An incorrect power source may damage the device or be hazardous. • Never connect the device to overloaded outlets or extension cords. • If there is any visible damage to the power cord or other components, do not operate the device. 3. Operation and Ventilation: • Place the device on a stable, flat surface. Do not block any ventilation slots to prevent overheating. • Ensure sufficient distance from other devices or walls (at least 10 cm) to ensure optimal ventilation. 4. Children and Pets: • Keep the device away from children and pets, especially small parts that could be swallowed.
Speakers:
1. Setup: • Place speakers on a stable and secure surface or use suitable speaker stands. Tipping over may cause injury or damage. • Position speakers so they are not obstructed and optimal sound dispersion is ensured. 2. Environmental Conditions: • Speakers are intended for use in dry, enclosed spaces. Avoid moisture and direct sunlight, which could damage materials or electronics. 3. Connections: • Use only compatible amplifiers and cables that meet the speaker's technical specifications. • Avoid incorrect polarity connections to prevent damage to the speaker or amplifier. 4. Children and Pets: • Speakers are not toys. Make sure they are placed out of reach of children and pets. 5. Care: • Clean the surface with a soft, dry cloth. Do not use chemical cleaners or water.
Cable:
1. Use: • Cables are for their intended use only. Use them only with devices that meet the cable's technical specifications. • Ensure that all connections are secure and tight for optimum performance. 2. Handling: • Never pull on the cable to remove it from a device. Always hold the plug firmly. • Do not bend, overstretch, or place excessive strain on the cable. Cables should not run under heavy objects. 3. Children and Pets: • Keep cables away from children and pets as they can be a strangulation or injury hazard. 4. Inspection: • Check cables regularly for visible damage such as breaks, cracks, or frayed ends. Damaged cables must be replaced immediately.
Accesories:
1. Use: • Accessories such as adapters, mounts or cleaning utensils must only be used for their intended purpose. Incorrect use can cause damage. 2. Care: • Clean accessories only according to the manufacturer's instructions. Avoid harsh cleaning agents or use in damp environments. 3. Safety: • Ensure accessories are correctly fitted or connected to prevent accidents or malfunctions. 4. Children and pets: • Accessories, especially small parts, pose a choking hazard and should be kept out of reach of children and pets.
