Neumann V 402 Mic preamplifier
2024年 3月 3日より、IC-7610に換装。 現在の送信には基本性能を忠実に発揮させて自然な音声を求め
Neumann TLM102 コンデンサーマイク → Neumann V402 マイクプリアンプ → IC-7610 。
受信＆モニターには、Neumann NDH-20 ヘッドフォン & Neumann KH-80 スピーカーを併用。
音振れの無いように同一メーカーで揃え、非常にシンプルな組み合わせで運用しております。
人は、それぞれに持って生まれた声（個性）があります。 それを生かして、ほんの少しのコーディネートをすることで『声の輪郭や品』を加えることができます。 よって、本来の自分の声を劇的に変化させるために使うものではありません。
時代とともに、パソコンとソフトウェアで音質管理が可能になりましたが、音声信号の遅延や回り込みなどの障害もあります。 ご覧のようなアナログ機器は、時代を超えても操作感が一目瞭然で非常に明快です。
私生活を含めて基本的に 『作り手』 がしっかりと見えるものが好みです。 物に対する考え方、造りこみ、美しさなど。 自分の価値観と合致したものであれば多少の対価は厭いません。 妥協をするのではなく自分が許せる範囲の中でアイテムを取り揃えて構築しています。

Neumann V 402
The Neumann Mic Preamp V 402 is a state-of-the-art dual-channel mic preamp with a built-in professional studio-grade headphone amplifier. The transformerless circuit is designed for maximum clarity and sonic purity. The V 402 is thus the perfect complement to all Neumann microphones to bring out the true personality of voices and instruments.
We believe that the best combination of Neumann microphones currently used in amateur radio is a Neumann microphone preamplifier. When you monitor your own voice through the microphone, you can clearly feel the difference. If you hear a sound that sounds like nothing you've ever heard before, it's probably because your sense of pitch has become sharper.
◆A state-of-the-art dual channel transformerless mic preamp that perfectly complements all Neumann microphones.
◆Two studio-quality instrument inputs with very high impedance
◆Switchable low cut removes rumble without degrading the signal
◆Extremely clean studio quality headphone amplifier
◆Easy monitoring mix with volume adjustment for each channel
◆Handmade production by Neumann expert engineers in Germany

CLASSIC PRO / PDM/LSII
Power distributor for radio equipment and peripheral audio equipment.
The power supply area, which tends to be complicated, can be managed all at once, and nine power supplies can be obtained from this housing.
It also provides clean power through a noise filter and surge filter.
★Spike, surge filter
Instantaneous and sudden changes in voltage/current caused by lightning etc. will weaken in an instant. As a result, damage to the sound system and equipment can be prevented and troubles can be avoided.
★Noise filter protection circuit
It provides the best sound quality by minimizing noise entering the power line and avoiding the negative effects on sound quality caused by the presence of a filter.
★Excessive power protection circuit
Even if an abnormal voltage such as excessive voltage supply or low voltage occurs due to a problem with the power supply or a cable connection error, the protection circuit will activate and automatically shut down to protect the equipment.
★Equipped with a liquid crystal display that displays voltage, current, and time
The power status is obvious at a glance.
Voltage and current can be monitored in real time.
★Equipped with front LED light
Equipped with two pull-out and angle-variable LED lights on the front panel. Supports operation in dark places.
★8-step sequence function
You can turn ON/OFF from 1ch to 8ch in order. (ON: 1→8, OFF: 8→1)
You can prevent noise from entering the speakers by connecting the power outlets in the order in which the speakers are turned on. The interval between channels is approximately 1 second.
Neumann KH80 DSP
NEUMANN (Germany)
2 KH 80 DSP speakers
KH 80 DSP is a 2-way powered monitor speaker equipped with a 4”/1”+120W/70W high efficiency amplifier.
Although it is a compact 4-inch size that is ideal for home environments, it achieves low frequency reproduction approaching that of a 5-inch model.
The KH 80 DSP, which is equipped with a 4-inch woofer, is a model that is equipped with a sound quality adjustment function using DSP.
The KH 80 DSP has a 4-inch woofer that provides wideband playback of 57Hz to 21kHz, making it a compact speaker that is ideal for home studios, yet allows you to clearly hear low frequencies.
Not only music, but also amateur radio reception sound is monitored with these two Neumann KH80 DSP speakers.
Built on digital technology, the KH 80 DSP delivers studio-accurate monitor sound in any environment with filtering and room adjustment options.
The traditional strengths of Neumann's monitor philosophy include a compact design with incredible adaptability, directivity optimized for the listening position, vibration-reduced cabinet design, and sophisticated material selection. Equipped with:
■Type: 2way
■Frequency characteristics: 57Hz - 21kHz ±3dB
■Amplifier output:
Tweeter amplifier maximum output: 70W
Woofer amplifier maximum output: 120W
■Woofer: 100mm (4”)
■Driver: 25mm (1”)
■Maximum output sound pressure level: 108.8dB
■Input terminal: XLR/6.3mm (balanced)
■Dimensions: W154 x H233 x D194(mm)
■Weight: 3.4kg
■Remarks:
■Built-in DSP, gray

Connector & Cable
Typical cables are hot, cold, ground (and shielded) 2-core and shielded wires.Neumann's microphone cable has three independent cores: hot, cold, and ground, and has a separate shielded wire on the outside, which is a "special design".is.
NEUMANN microphone cable
★Neumann microphone cable
Most normal consumer cables are 3-pole/3-pole and will still produce sound, but 4-pole/4-pole cables are the strongest and most suitable for Neumann condenser microphones.
It is a 3-core cable with perfectly balanced transmission, and has 4 wires for both male and female connections, so the noise is said to be 1/10th that of regular microphone cables. This cable is fully wired with 4 poles and 4 poles, and is made with 8 connections.
When connecting and using a Neumann condenser microphone, a dedicated ground wire is used instead of a shielded wire for phantom power, making it possible to supply clear phantom power.
NEUTRIK connector cable
★Neutrik is a Liechtenstein company that manufactures connectors used in audio and video recording studios and concert sound systems.
Although it is about 10 times more expensive than general connector cables, it has a solid construction and quality that is unsurpassed.
We also paid attention to all the cables that connect the microphone to the equipment.
We keep the wiring as simple as possible, with efficient lengths and appropriate connectors and cables.
It all comes down to a reliable connection, hum, and prevention measures.
