Installation
The ART Solo Studio may be used in a wide variety of applications and environments. In a 1U rack-mountable, all-steel enclo-
sure, the unit is designed for continuous professional use. Mounting location may not be critical but, for greater performance reli-
ability, we recommend that you not place the unit on top of power amps or other sources of heat and/or strong magnetic fields.
Note: The tube circuitry needs about a minute to "warm up" and stabilize from a cold power up.
AC Power Hookup
The ART Solo Studio has an internal power supply, only connect the unit to mains power of the type marked on the rear panel.
The power source must provide a good ground connection and the ground pin on the mains plug should never be defeated.
Audio Connections
Audio connections to and from the SOLO VLA are:
CONNECTIONS
Unbalanced 1/4-inch cables may be used with no damage to the SOLO VLA. We recommend using only high-quality
cables equipped with the appropriate connectors.

1. Power Switch
When the main power switch is engaged, the unit is powered "on." The VU meter will light. Switch LED's will light if its associ-
ated switch is in the "in" position. Power on the Solo Studio before any monitoring outputs or power amps are turned on.
Note: The Solo Studio should be turned "on" with all monitor levels turned down to protect against any "thumping"
caused by power up. Likewise, the Solo Studio should be turned "off" after turning all monitor levels down.
Note: Like all tube-based equipment, the Solo Studio needs to warm up to operating temperature. The 12AT7 tube
will reach operating temperature within one to three minutes. During this warm-up period you may experience
sound variations due to the bias of the tubes stabilizing. This is normal and the Solo Studio will provide consistent
results once the warm-up period is over.
Note: If the Solo Studio fails to power up when the POWER switch is turned on, check to see that its power cord is
plugged into an active outlet. Locate the fuse installed in the IEC connecter, verify that the fuse is not blown, replace if
blown with the same type and value fuse. If the unit still fails to operate properly, turn it off and unplug it. Then consult
your dealer or Customer Service Department through www.artproaudio.com.
2. Input Combo-Jack
The Solo Studio 's combo connector follows the AES standard of Pin 1 = Ground, Pin 2 = Hot (+), Pin 3 = Cold (-). The
Balanced inputs have an input impedance Balanced 47K ohms and >800K ohms Un-balanced. The Maximum input level
is +19dBu balanced and +17dBu unbalanced.
3. Phantom Power Switch / Clip Indicator
The PHANTOM switch safely applies +48V phantom power to the XLR input on the front and rear panel. In addition to indicating
whether Phantom power is enabled, this LED also indicates clipping (red), even when PHANTOM power has been disabled.
Note: Use phantom power only when the microphone that you are using requires it. Doing so will reduce the
possibility of shock hazard.
