I did not find a manual for the Conductor 3GT (not X)

The System

Listening with

Abyss Diana MR · Headphones: open-back, planar magnetic, circumaural

Impedance: 30 Ω
Sensitivity: 93 dB/mW ≈ 108.2 dB/V (calc.)
Frequency response: 2 Hz – 45 kHz (-3 dB @ 5 Hz)
Plugs / cables supplied: JPS Labs 1.5 m cable with 3.5 mm, 6.3 mm, 4-pin XLR or 4.4 mm plug

Matching notes: At 30 Ω and 93 dB/mW, the Abyss Diana MR is a low-impedance load: about 1.2 V (50 mW, 41 mA) for 110 dB SPL (calc.). Burson does not publish a 30 Ω rating for the Conductor 3X GT. Its 16 Ω and 32 Ω ratings (10 W XLR / 5 W SE; 8 W XLR / 4 W SE) fall either side of it. The Conductor 3X GT’s 0.5 Ω headphone output impedance is 1/60 of the load. ^{[1] [2] [3] [4]}

Specs from manufacturer data unless a source below says otherwise. “calc.” values are worked out from those figures (V = √(P × R); 110 dB SPL used as a loud reference level). Gear listed without specs is not in our spec library yet.
