MTR DI-3 Active Mono DI Box *SOLD*
£25
Margate

Recommended Posts

MTR DI-3 Active Mono DI Box in great condition with original box and manual. 

This DI has been on my board for a couple of years and has worked faultlessly. 

"The MTR DI-3 single channel D.I. box can be powered in 3 different ways: by a 9 volt PP3 battery, phantom power up to 48v from the desk (or an MTR PPS-48), or an external 9v regulated power supply into the DC socket on the left edge. 

The MTR DI-3 has a mono jack input, and link out socket to, for instance, an on stage or in studio combo, a ground lift to eliminate hum loops, a three position attenuator for accurate level matching, and a balanced 600 ohm XLR output. The active electronics have a purely resistive high input impedance, and so do not colour the sound.

* Frequency response: 20Hz-20kHz ±1.5dB.

* Distortion: (THD) < 0.005% at 1kHz, 0dBu

* Output noise: <-100dB unweighted

* In/Link impedance: 1MOhm, jack.

* Output impedance: 600 Ohms balanced XLR.

* Attenuation switch: -40dB, -20dB, 0dB.

* Ground Switch: lifted/connected.

* DC Input: 9vDC, 100mA, neg. centre pin

* Phantom Power: +18 volts DC to +48 volts DC

* ‘Low Battery’ led: glows @ approx. 6v"

 

Collection from Margate, or I can post if required.
