Preamp Two Mk 6

phono MC/MM + Line preamp

 
Preamp Four Line
 

Design * Construction

. full tube technique in signal path
· MC- and MM-input stage
· low noise phono input stage
· passive phono pre-emphasis
· RIAA-phono de-emphasis stepwise switchable for different cut off frequencies
· switchable input impedances for MC- and MM-operation
· 3-steps MC-adjustment by switchable transmission ratio
· pure class A-operation
· galvanic isolation by output transformer coupling
· catridge module technique
· balance/volume control by processor controlled relays and resistors
· volume adjustment with high resoultion and wide control range
· equal balanced-unbalanced in-/outputs by transformer technique
· all functions relay-controlled
· flexible switch functions by processor control
· balanced or unbalanced output
· internal switch mode power supply for all operation voltages
· on / off muting


Front panel rotary step switches

· front panel rotary switch 2 x phono, MC/MM, CD, 2 x tuner/line
· step switch mode for selection of RIAA-phono-cut off frequency
· front panel rotary switch balance 16 x 0,7 dB-stepwise
· front panel rotary switch volume 120 x 0,7 dB-stepwise
· front panel rotary switch on for on/off and volume adjustment store


Front panel optical elements

· LED for operation display
· remote control receiver
