Crystal-Line CL40S
- 4 Channel Universal Line Level Adapter/Driver & Cell
Audio Switch
- Inputs & outputs support single ended/unbalanced as well as differential/balanced connections
- Isolated Current Balanced™ inputs & outputs break
ground loops and eliminate extraneous ground currents that cause shared
impedance effects
- 24 volt p-p/9+ Volts rms single ended, 48 volts p-p/18+ Volts rms differential,
input & output levels
- DC Coupled input & output circuits, uses only one blocking capacitor in
overall signal path
- Resistor plug programmable gain/attenuation
- 1Ω DC Coupled Output Impedance

Crystal-Line CL0.2
- 2 Channel Line Level Adapter
- Inputs support differential/balanced/bridged as well as single ended/unbalanced
connections
- Isolated signal pathway will not create a ground loop and will preserves
current balanced™ Lines
- Independent ouput line level controls
- Resistor plug programmable input level gain/attenuation
- Can be wired to combine front and rear channels for hiss reduction
by correlation averaging
- 2Ω Output Impedance @ 1kHz
