TECHNICAL INFORMATION The first stage of the NEOX400-210T preamp uses a low noise bi-fet linear scaling amplifier with a 2 pole low cut point at 23 Hz to prevent excessive speaker cone excursion and intermodulation distortion. Additional bandwidth roll-off is provided at 20 kHz for RFI suppression. The variable gain stages are a feedback-divider type control, one of which is all solid state and the other utilizing a cathode follower (tube), each providing a maximum gain of about 30 dB. On the tu

features may be provided with the active pickup, such as equalization, volume control and compression. Tuner Output Jack — The “tuner output jack is provided to allow a tuner to remain plugged into the amplifier while playing. This output remains active when the “mute switch is pressed, allowing for tuning your instrument while not sending signal to either the “direct output or the speaker. Signal level of -30dB (typical hot bass level) will drive all known tuners. Input Signal Mute Switch — T

LED will illuminate for approximately 3 seconds during power switch-on and switch-off. It is normal for this LED to glow while continuing to monitor the internal conditions for about 3 seconds after the protection relay has closed. It will also illuminate during any internal fault condition. If this happens, turn the amp off and consult a repair technician. • The “thermal LED indicates that the amplifier has overheated, engaged the protection circuit and shut down.

chorus, delay and reverb processors) require that the signal flow out of the send jack on the amplifier, through the unit where it is split into a dry (unaltered) signal and a wet (processed) signal. On the processing unit, you will use the mixed signal output to return the signals (both wet and dry) to the return jack on the amplifier. The ratio between the wet signal and the dry signal is heard as the amount of effects added back to the original signal, which is controlled by the mix knob (als
