Design Features
Summary of Phono 1 Design Features
1.
Custom extruded & machined aluminum chassis provides a stable, rigid
base plus the beautiful solid cherry wood face plate, rails and feet enhance
the aesthetics and improve vibration control of the system.
2.
Microprocessor controlled Vacuum Florescent Display (VFD) & Logic
3.
Internal USB software upgrade port
4.
High quality polytetrafluroethylene (PTFE) insulation and rhodium plated
unbalanced connectors for maximum reliability and low Elector-magnetic
Interference (EMI)
5.
High quality pro-audio grade gold plated balanced connectors for maximum
reliability and low Electro Magnetic Interference (EMI)
6.
2 unbalanced RCA selectable line level inputs
7.
1 balanced XLR line level input
8.
2 unbalanced RCA selectable outputs
9.
1 balanced XLR selectable outputs
10.
Balanced inputs/outputs are transformer coupled giving high Common
Mode Rejection Ratio (CMRR) for low noise operation with optional pin 1
ground lift to suppress inter-chassis ground loops
11.
Individual ground path for left/right channels to increase immunity to
ground loops and inter-channel crosstalk
12.
3 position ground selector per channel to equalize ground potentials and
minimize system residual noise
13.
Input/output audio signal switched concurrently to avoid audio ground mix-
ing/noise summing thereby maximizing signal to noise performance
14.
Audio amplification circuits employ New Old Stock (NOS) 2 x 8416 (10,000
hour) & 2 x 6n6p (5,000 hour - optimized for 10,000 hours) high grade se-
lect vacuum tubes in pure class A with zero negative feedback delivering
ultra-low distortion - thereby maintaining the natural harmonic structure
of the audio signal
15.
Software selectable Gain levels of 55db to 70 db in 5 db increments
16.
