4.1 Input panel controls

The input panel has a combination of controls and connectors for a wide variety of control and
configuration.

1. LCD – DSP control and monitoring interface.

2. MASTER VOLUME - Contextual rotary and push knob that is used to adjust and navigate
the DSP menu and to adjust parameters (for example Master Gain).

3. INPUT LEVEL - Rotary knob used to adjust the level of the corresponding input. The
detent 12 o’clock position represents unity level (no gain or attenuation). Rotate the knob
to the left to attenuate LINE level sources, or rotate to the right to add gain to MIC level
sources. There is an input level control for INPUT 1, INPUT 2, and INPUT 3.

4. POWER – AC switch for switching the power ON or OFF. The LCD screen lights up when
the power is turned ON, after approximately 3 seconds.

5. MIX OUT - A post-input level sum of all three input channels. This allows for the ‘mix’ to
be sent to a secondary device, such as a PA or recording device. It can be adjusted in
DSP to output a stereo signal (L+R) or an isolated RIGHT channel. This is ideal for
connecting LEFT mains to RIGHT mains in a PA configuration.

6. THRU - An output that is parallel to INPUT 1. This is not affected by the DSP of the
system. It is used to daisy-chain the signal of INPUT 1 to an external device.

7. INPUT 1, 2 - Balanced MIC/LINE XLR/TRS inputs to connect a line level signal source
(such as mixer, etc.) or a microphone. Whenever possible, balanced signal feed is always
preferable to guard against potential noise.

8. INPUT 3 - Unbalanced stereo RCA input to connect LINE-level signal sources, such as
mobile devices or media players.

9. MAINS IN - The device receives its power supply via the MAINS IN socket. Use the
included IEC power cord to connect the system to a stable, grounded power source.
Connect the device only to an electrical outlet that is capable of providing the voltage and
current outlined on the product label and system specifications.

4.2 System status

Normal

1. LEVEL – Indicates the master gain of the system in dB. The range is from mute to +10 dB,
in 1 dB increments.

2. 1 - Indicates the current recalled preset number. There are five presets available for
storing and recalling.

3. E - Indicates that the current recalled preset has updated parameters and is not saved.

4. IN1 - Indicates in meter form the magnitude of signal present on INPUT 1.

5. IN2 - Indicates in meter form the magnitude of signal present on INPUT 2.

6. IN3 - Indicates in meter form the magnitude of signal present on INPUT 3.

LIMIT

LIMIT indication is displayed when gain reduction is being applied to the signal. This allows
the loudspeaker to continue operating while preventing the amplifier and components from
exceeding their functional capability. Levels operating continuously beyond the limiter
threshold must be avoided.

PK

When PK (peak) is indicated, the INPUT signal magnitude is higher than what the amplifier can
handle and is effectively clipped (distorted). Lower the volume of the signal source and/or
lower the INPUT LEVEL by rotating the corresponding INPUT LEVEL knob counter-clockwise.
The PK status must be avoided at all times. Even momentary bursts of clipped signal can
severely damage system components.

PHANTOM 1 and 2 - Activates a +15V phantom power supply on INPUT 1 and/or INPUT 2. This
is a sufficient voltage for use with most condenser microphones.

MIX OUT - Adjusts the routing and summation to the MIX OUT output. Adjust this parameter
when a stereo image is desired from two systems.
– L + R - The LEFT and RIGHT signals of INPUT 3 are summed and output to both the

loudspeaker and the MIX OUT output.

– R - The RIGHT signal of INPUT 3 is routed directly to the MIX OUT output. The

loudspeaker will only output the LEFT audio signal.
In both settings, the signals from INPUT 1 and INPUT 2 are also summed and routed to the MIX
OUT output.

DELAY - This parameter sets the amount of audio delay that will be applied before the signal
is output to the loudspeaker. This is useful for compensating the differences between
speakers at different distances from the listener. MIX OUT and THRU outputs are not affected.

6 Troubleshooting

Problem Possible Cause(s) Action

1. No sound Amplifier Verify all the electronics are on, the signal routing is
correct, the source is active; the volume is turned up,
etc.
Correct/repair/replace as necessary. If there is still no
sound, then the problem may be wiring.

Wiring Verify you have connected the correct cables to the

amplifier. Play something at a low level through the
amplifier. Connect a test loudspeaker in parallel with the
malfunctioning line. If the sound level is gone or is very
weak, the line has a short in it (possibly a severe scrape,
pinch, or a missed connection). Using the test
loudspeaker, move down the line and test each
connection/junction until you find the problem and
correct it. Observe proper polarity.

2. Poor Low-

Frequency

ensure they are all clean and tight. If the problem
persists, check the wiring. See problem 1.

If noise is present, but no program material is playing,
evaluate each component as necessary to isolate the
problem. Most likely there is a break in the signal path.

Check and correct the system grounding, as required.

Slowly increase the input gain knob level to engage the
microphone pre-amp.

Switch PHANTOM 1 or PHANTOM 2 to ON in the menu.
