Pro Setup Menu Level Nine – Mono Enhancements
Mono Enhance is a proprietary ADA processing mode designed to improve playback of monaural
source material with no separation. This enhancement feature first sums the left and right channels,
then adds delay to the left channel with respect to the right channel. This delay is set prior to any Pro
Logic decoding and delivers surround sound with depth and feel, instead of playing audio only out of the
center channel.
The two Mono Enhancement parameters that can be adjusted are Effect Delay and
Effect Level. The Effect Delay parameter allows you to add up to 20 mS of delay to the left channel
with respect to the right channel. The Effect Level parameter sets the actual amount of the effect from
–20 dB to + 20dB. We recommend playing back a monaural source while adjusting the Mono
Enhancement parameters.
To Set Mono Enhancement Parameters
1. Select an Input label that is playing a monaural signal and press the Input knob.
2. Press and hold the Mode knob until the display changes to the Tone, Balance, and Volume
recall setup.
3. Rotate the Mode knob until the cursor is flashing over the P in PRO SETUP.
4. Rotate the Mode knob until the cursor flashes over the E in EH.
5. Press the Mode knob. The cursor will flash over the M in MONO ENHANC LEVEL
6. Rotate the Mode knob until the cursor flashes over the M in MONO ENHANC DELAY.
7. Rotate the Input knob to set the amount of left channel delay.
8. Rotate Input knob back until the cursor flashes over the M in MONO ENHANC LEVEL.
9. Rotate the Input knob to set the amount of mono enhancement.
Pro Setup Menu Level Nine – Solo Test Mode
The Solo Test mode is ADA’s proprietary multi-channel monitoring mode. The Solo Test mode permits
you to have just one speaker playing while all other channels are muted. You can select just one channel
and easily switch between single channels while in the Solo Test mode. This feature is useful when
trying to determine if you have a damaged speaker or driver. The Solo Test mode is also ideal to gain an
understanding of how different multi-channel recordings are mixed because it allows you to listen to
one channel at a time. The unique feature is particularly interesting when playing back multi-channel
music recordings where you can actually isolate individual instruments and vocal tracks. To achieve the
Solo Test mode on other preamplifiers would require you to individually turn down the gains of each
amplifier channel except the one under test.
To Activate the Solo Test Mode:
1. Press and hold the Mode knob until the display changes to the Tone, Balance, and Volume
recall setup.
2. Rotate the Mode knob until the cursor is flashing over the P in PRO SETUP.
3. Press the Mode knob. The display will change to the Pro Setup menu.
4. Rotate the Mode knob until the cursor flashes over the S in SOLO TEST.
5. Press the Mode knob. The display will change to the speaker level menu with the cursor flashing
over the O in OFF.
6. Rotate the Mode knob until the cursor flashes first letter of the channel you want to solo test.
7. Press the Mode channel to mute all other channels. You can adjust the volume level of the
channel under test if you wish.
8. You can exit the Solo Test mode by accessing <P or M>.
