Musical Paradise MP-701 Preamp User Manual

Input

MP-701 MK2 provides three RCA inputs (IN1, IN2 and IN3) and one XLR

input. XLR input shares with IN3 RCA input, so the user needs to choose

either XLR or RCA cable connected to IN3. Cannot connect both at the

same time to IN3. The input impedance of MP-701 MK2 is 100Kohm which

is an easy load for all kinds of source devices.

Output

MP-701 MK2 provides two RCA outputs and one XLR output. They are

connected in parallel and shares the same audio signal output from the

tubes and coupling capacitor. For optimal result, the total impedance of

the connected devices must be higher than 10Kohm. For example, the

input impedance of a power amp is 100Kohm, and the impedance of an

active sub-woofer is 100Kohm. The total impedance drops down to

50Kohm.

Tube Replacement Guide

MP-701 MK2 supports 6Z5P, 6X5, 5T4, 274B, 5AR4, GZ34, GZ33, 5R4, 5U4G

rectifier tubes.

When using 6Z5P and 6X5 rectifier tubes, S2 switch must be set to 6X5 position.

When using 5T4, 274B, 5AR4, GZ34, GZ33, 5R4, 5U4G rectifier tubes, S2 switch

must be set to 5AR4 position.
