ASP880 Input Information

Microphone Preamplifiers & Line Inputs

• 8 hybrid class-A microphone preamplifiers (contain both transistors and op-amps)
• Optimised for 0 to 60dB gain with an EIN (equivalent input noise) of -127.5dB.
• Switchable -10dB pad on channels 1+2 to provide a -10 to +50dB padded gain range
• Inputs provided on the rear panel using Combi XLR connectors, where the ¼” Combi Jack connector provides a padded balanced line input (input impedance  >6kΩ)
• Input impedance switch functions as a variable pad for any line input signal.

D.I Inputs

• Two discrete class-A JFET D.I. inputs (Channels 1+2)
• Plugging in jacks to the connectors on the front panel will automatically select the D.I. signal over the signals present at the rear.
• Input impedance >1MΩ
• When pushed, the JFET circuit will provide 2nd and 3rd harmonic distortion to give the input a rich sound and colour.

ADC Direct Access

• ADC balanced line inputs available on the rear panel DB25 connector (Tascam format)
• Direct access to AD converter with +18dBu input headroom (0dBFS = +18dBu) for line level signals.
• Provides a path for inserts between the mic preamps and the ADC.
• Activate direct AD access by pressing the A-D button on the required channel.

* Line input level at the combi jacks will be affected by the input impedance switch position, this can be used as a second pad control to adjust line input ranges on all channels.
