1073N Channel Amplifier Issue 1.4
Configuring the 1073N for Neve rack or Original BCM10
When the 1073N is used in a Neve 3U or 5U rack or an original BCM10
console the rear panel input and output connections, power switch,
fuse and phantom power controls are not used. The following
configuration should be used for the remaining controls:
u Set ‘EXT LVL CTRL’ switch to YES: This routes the 1073N audio
through the volume control of the rack or console.
u Set ‘5k1 TERMINATION’ to OFF: This removes the 5.1kW resistance
from the signal path to ensure correct frequency response.
u Set Mic Impedance to match the microphones you are using: Low
impedance = 300W, Hi impedance = 1200W.
In most cases you would set this to Hi.
Configuring the 1073N for Neve 45 series consoles including the new 2016 BCM10
When the 1073N is used in a Neve 45 series console without fader
connections (most 45 series consoles other than the original BCM10) the
rear panel input and output connections, power switch and
phantom power controls are not used the following configuration
should be used for the remaining controls:
u Set ‘EXT LVL CTRL’ switch to NO: This routes the 1073N audio
internally.
u Set ‘5k1 TERMINATION’ to YES: This terminates the high pass filter
correctly to ensure correct frequency response.
u Set Mic Impedance to match the microphones you are using: Lo
impedance = 300W, Hi impedance = 1200W.
In most cases you would set this to Hi.
