MIXERS

This section description starts in reverse to show the signal flow options from arrival to the various outputs.

15. LEFT/RIGHT MASTER FADERS: Depending on their position, the left and right master faders attenuate
or amplify the combined L and R signals arriving from all the input channels. These resulting signals can be
seen on the VU meters (14).

14. LEFT/RIGHT VU METERS: According to the master fader settings (see above), these meters show the
amount of signal being sent to the MAIN LEFT/RIGHT outputs (1) and subsequently to a PA system or
recording device. Note: ARTHUR PRIME has 30 dB of headroom, so its electronics and output amps are
rarely likely to clip. The main purpose of these meters is to monitor the level of signal flow to successive audio
devices.

13. HP OUT: Headphones can be connected to this socket for independent monitoring of the sound.

12. VOLUME: This lets you adjust the volume level of your headphones. Note: The signal level you will hear
from the L/R MASTER through your headphones is not related to the level determined by the master fader
positions.

DIGITAL STEREO REVERB – USING THE INTERNAL EFFECT
The volume and decay of ARTHUR PRIME’s high-quality internal reverb can be independently controlled on
the main outputs – this is unique!

10. DECAY R and 11. REV RIGHT: These controls let you regulate the reverb and its decay on the right
channel.
