Linsoul E1DA Cosmos Scaler Headphone Amp Preamplifier, High

Linsoul E1DA Cosmos Scaler Headphone Amp Preamplifier, High Performance Low-noise Low-distortions Variable Gain Pre-amp with Volume Knob Control for Audiophile Musician

• 【𝐋𝐨𝐰 𝐃𝐢𝐬𝐭𝐨𝐫𝐭𝐢𝐨𝐧 & 𝐇𝐢𝐠𝐡 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞】E1DA Cosmos Scaler is an exceptional high-performance, low-noise, and low-distortion variable gain pre-amp designed explicitly for the Cosmos ADC. Precise measurements are challenging due to the immense loop gain OPA1612+OPA1656 composite. However, estimates suggest it's about 100 times lesser than the Cosmos ADC or H3, sitting at around -175db@1kHz at 0db gain.
• 【𝐏𝐫𝐞𝐦𝐢𝐮𝐦 𝐐𝐮𝐚𝐥𝐢𝐭𝐲】Made with sandblasted, black anodized aluminum featuring precise laser markings. Internally, it's composed of a composite of OPA1612+OPA1656, Viking resistors, Murata and Samsung C0G capacitors, and quality connectors/relays sourced from Taiwan.
• 【𝐕𝐚𝐫𝐢𝐚𝐛𝐥𝐞 𝐆𝐚𝐢𝐧 𝐓𝐚𝐛𝐥𝐞】Ultra-low THD+N variable gain buffer tailored for Cosmos ADC. This device comes with 16 positions that can be adjusted using its knob. Ranges from 0db to 26.078db. Notably, in the "Auto" position, the Scaler acts as an ultra-fast autoranger (100mS) with the left channel targeting 4.5Vrms. Only the 20Hz-20kHz range is valid for the autoranger.
• 【𝐅𝐫𝐞𝐪𝐮𝐞𝐧𝐜𝐲 𝐑𝐞𝐬𝐩𝐨𝐧𝐬𝐞】The Scaler exhibits a remarkable frequency response of .2Hz-570kHz @ 26db gain +.5/-3db. It can stretch up to .2Hz-7.11MHz @ 0db gain, although this heavily depends on the cable's capacitance. It's stable up to 7m of mic cable.
• 【𝐔𝐧𝐢𝐪𝐮𝐞 𝐌𝐎𝐍𝐎 𝐦𝐨𝐝𝐞】 When only the left input is utilized, the signal automatically routes to the right channel as well. Moreover, the Cosmos APU's short cables are seamlessly compatible with the Scaler.

𝐂𝐫𝐨𝐬𝐬𝐭𝐚𝐥𝐤: Demonstrates exceptional crosstalk performance with L->R at -133db and R->L at -158db@1kHz when unused input is shorted at 0db gain.

𝐑𝐞𝐬𝐢𝐝𝐮𝐚𝐥 𝐍𝐨𝐢𝐬𝐞: A minimal noise footprint of 250nVrms(A) @ 26db gain.

𝐏𝐨𝐰𝐞𝐫𝐢𝐧𝐠: Through a USB-C +5V rail with a current consumption of less than 500mA.
