To connect the 586 to your system, refer to the following steps:

• Turn off all equipment before making any connections.

• If desired, install the 586 in your rack with the rack screws provided.

The 586 can be mounted above or below anything that does not generate excessive heat. Ambient tempera-

tures should not exceed 113ºF (45ºC) when equipment is in use. Although the unit is shielded against radio

frequency and electromagnetic interference, extremely high fields of RF and EMI should be avoided where

possible.

• Make audio connections via XLR, 1/4"TRS, or 1/4"TS plugs.

Both types of connectors for the inputs and outputs can be used for balanced or unbalanced connections.

However, the use of more than one connector at a time for the input pair could unbalance balanced lines,

cause phase cancellations, short a conductor to ground, or cause damage to other equipment connected to the

586.

• Verify that the fuse installed in the pull-out fuse holder of the fuse receptacle matches the type

and rating corresponding to the voltage in use as indicated on the rear panel of the 586.

• Apply power to the 586. Connect the AC power cord to the AC power receptacle on the back of

the unit. Route the AC power cord to a convenient power outlet away from audio lines.The unit

may be turned on and off from the rear panel power switch or from a master equipment power

switch.

Connecting a mic to a console.

1. Connect your mic cable to the Mic input of the 586 (See Figure 1, next page).

NOTE: If you are using a mic with a separate power supply, such as a tube microphone, make sure that you are

not sending 2 sources of +48V phantom power to the mic. Use the +48V from the mic's power supply.

Use the +48V Phantom Power switch on the 586 for all other microphones which require phantom

power.

2. Set the front panel of the 586 to the desired settings, including phantom power, pad, phase, etc.

Connect the Line Output of the 586 to the console's LINE INPUT, and ensure that the console's

input selection switch is set to LINE, and the console's gain control is set appropriately low. Set

the rear panel switch on the 586.
