MU-2 TUBE PHONO PREAMPLIFIER
v1.2
MU-2 features
MM (Moving Magnet) and MC (Moving Coil) cartridges support
Input impedance matching in range 50Ω-1kΩ for MC carts.
„On the fly” input impedance change during music listening with automatic mute function
Warm-up function: signal is attached to outputs with delay mandatory to stabilize tubes
operating points.
Immediate outputs detach when device is switched off or in case of AC mains is down.
Physical separation of left and right channel path to decrease stereo channels cross talk
High quality resistors (1% tolerance) and capacitors (1% and 5% tolerance) in audio path for high
stability and accuracy of RIAA frequency correction curve.
Microprocessor controlled circuit
Connection
1) Carefully take MU-2 out of the shipping carton and plastic bag. Use soft gloves if possible to
avoid fingerprints on stainless steel cover. Do not hold glass front panel by hand.
2) Place preamplifier in proper distance (minimum 10cm) from other electrical equipment like
amplifier to avoid electromagnetic
interferences. Take care about proper
ventilation because preamplifier generates
heat.
3) Connect RCA cables from turntable to RCA
inputs of MU-2. If turntable tonearm is
equipped with grounding cord connect it
to GND socket.
4) MU-2 outputs connect to high level inputs
of integrated amplifier or line preamplifier
(inputs marked AUX, CD, DVD etc..).
WARNING! Do not connect MU-2 to input
marked PHONO unless it’s Muarah MU-4 integrated amplifier.
5) Connect AC main power. WARNING! Main AC Power going to MU-2 should not be applied until
all the system components are connected together. AC mains power cord has to be connected
to MU-2 first and then to AC outlet.
