User manual RANE AP 13

[. . . ] This is an AC input and requires special attention if you do not have a power supply exactly like the one originally packed with your unit. See the full explanation of the power supply requirements elsewhere in this manual. WEAR PARTS: This product contains no wear parts. Manual-1 FRONT PANEL DESCRIPTION Acoustic INSTRUMENT INPUT: is a stereo ¼" TRS (Tip-Ring-Sleeve) INPUT jack for use with any acoustic instrument with two pickups; however, also accepts instruments with only one pickup. When using a mono cable, signal is routed to the TIP selected by the Input Wiring Switch (see ). MIC & PIEZO pickup input OVERLOAD indicators: An individual red indicator for each type of pickup. [. . . ] No surprises here: the tip is "+" positive, the ring is "­" negative and the sleeve is signal ground. MAIN OUTPUTS MONO button: Engaging this pushbutton combines or Monoes the Main A & B Output. EXPAND IN A & B jacks: Two unbalanced ¼" TS jacks used to expand the AP 13. These inputs sum (pre-Main Level control) with the Main A & B signals. As long as nothing is plugged into the B jack, the signal from EXPAND A automatically drives EXPAND B. INSERT loop A & B jacks: Two unbalanced ¼" TRS jacks wired per the tip=send, ring=return convention. Allows placing an outboard signal processor in series with the main signal paths. RETURN A & B jacks: Two unbalanced ¼" TS jacks used as the return path from the OUTPUTS of an outboard signal processor. As long as nothing is plugged into the B jack, the signal from RETURN A automatically drives RETURN B. SEND A & B jacks: Two unbalanced 1/4" TS jacks used to connect to the inputs of an outboard signal processor. PIEZO OUTPUT: An unbalanced ¼" TS jack gives a direct dry Output signal from the Piezo Pickup only. The PIEZO PICKUP OUT slider controls the amount of signal; however, since this Output is located after the PIEZO PICKUP LEVEL slider, then LEVEL also controls this Output. TUNER OUTPUT: An unbalanced ¼" TS jack used for direct tuner connection, fed by the PIEZO input. Located post EQ but pre-LEVEL, this Output is unaffected by either the LEVEL or OUT controls. Ground lift switch: provides the ability to separate chassis ground and signal ground. In some circumstances, moving it to the opposite position eliminates hum and buzz problems. Remote power supply input: This unit is supplied with a Rane RS 1 Remote AC Power Supply (RAP) suitable for connection to this input jack. Never use a power supply other that the one supplied or a replacement approved by Rane. Using any other type of supply may damage the unit and void the warranty. MIC PHANTOM POWER switch: controls the voltage used to power an electret or other condenser mic pickup. Chassis grounding screw: A #6-32 screw is used for chassis grounding purposes. See CHASSIS GROUNDING below. CHASSIS GROUNDING NOTE If after hooking up your system it exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration between units somewhere. [. . . ] A standard TRS insert style (tipsend, ring-return) Y-cord gets input and output from the INSERT jack to the effects unit. In the SEND and RETURN loop, the most you can obtain is a 50% effects signal, because the dry signal is internally mixed with the return. Another effects tip: If you want to put one effect on just the mic, and a different effect on just the piezo, but you want a mono output, just pan everything hard left and right for stereo and push the MONO switch on the rear of the AP 13. CONNECTING TWO GUITARS TO THE AP 13 A Y-cord can be used, as long as you don't try to run two piezo pickups. [. . . ]
