Iftach’s Burson Conductor 3X GT with Abyss Diana MR

• 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]}
