Heritage DTT-73

DUAL TABLETOP 73, it is in essence a reformatted DMA 73. The DTT-73 widens the range of application to onstage use, portable systems, hotel rooms, on location recordings, etc.

• Microphone input impedance: HI=1200 Ω minimum, LO=300 Ω minimum. Higher gain positions gradually have greater impedances, optimum for lo gain ribbon mics. Input is transformer balanced and floating.
• Line input impedance: 10 kΩ bridging, transformer balanced and floating.
• DI input impedance: Greater than 2 MΩ, unbalanced.
• Output impedance: Less than 75 Ω, transformer balanced and floating, to drive a load of 600 Ω (factory terminated).
• Maximum output: Greater than +26 dBu into 600 Ω.
• THD: Less than 0.025 % at 1 kHz, less than 0.05 % at 100 Hz.
• Frequency response: 20 Hz (+0.3 dB) to 20 kHz (-0.2 dB).
• Maximum gain: Slightly greater than 80 dB.
• Noise: Less than -100 dBu.
