Triode Corporation’s TRV-EQ3SE tubed phono/preamplifier features a low noise design with tube rectified power supply with IC regulator circuit. The point to point circuit design helps to maintain a pure signal path. Both MM and MC cartridges can be amplification, with an MC transformer of high efficiency being included that is 77 percent super permalloy EI core. The winding structure, precisely divided into layers, for wide bandwidth response and high rise time. Triode claims that, this provides “Good rise characteristics minimize a phase distortion in audible bandwidth and clarify great sound images. Reproduce realistic music with good S/N images.” The front panel controls include switches for MM, MC1, MC2, MC low, MC high and Low cut filter.
Frequency response is from 10Hz to 70kHz with a low 0.1 percent THD. Other features include: Input Level: MM 2.5mV, MC Low 0.23mV, MC High 0.19mV Input Impedance: MM 47K Ohms and MC 2-47 ohms Gain: MM 42.5dB, MC Low 58.7dB, MC High 64.4dB S/N Ration in Input: MM 90dB, MC 87dB Maximum Input Capability: 250mV (1kHz) 11mV Output Voltage: 200mV (1kHz) RIAA Curve Deviation: +/-0.25dB (20Hz to 20kHz) Channel Separation: More than 90dB Low Cut Filter: 15Hz @ 18dB oct Input Terminals: Three Lines (MM / MC1 / MC2) Output terminals: Two Lines (RCA / XLR) Capacitors: Mundorf Capacitor Resistors: Kiwame Resistors Tubes: Four ECC803 and one 5AR4.
