Block Diagram AC260

Specifications of the AC 260

Low Impedance In/Output:  600 ohms center tapped

(balanced).
Low Impedance Connector: XLR type jack.
High Impedance In/Outputs: 50K

.

High Impedance Connectors: 2- 1/4” mono phone
jacks

AC 265 Direct Box

Features of the AC 265

• Connects high impedance (50K ohms) to low imped-

ance (600 ohms), or low impedance to high imped-
ance.

• Ground lift switch to fix ground-loop hum problems.
• Allows a hi impedance unbalanced source to directly

feed a low impedance balanced input.

• Low distortion
• Low noise
• Adjustable attenuation pad, makes this different from

the AC 260.

Operation of the AC 265

• Connect the output of the high impedance source to

the input of the AC 265.

• Connect the low impedance output of the AC 265 to a

XLR
