CONNECTIONS- Inputs
Audio Input Connections
Input connections to the PL6.0 II can be made with XLR, TRS (1/4-inch), or terminal-block connectors.
The XLR/TRS connectors are “combo” style; they accept either XLR or TRS type inputs.
The terminal block connectors are three-pin “Euro-” (or “Phoenix-”) type. The accessory packet shipped with your amplifier contains two of these input connectors.
Each channel’s input connectors are wired in parallel (example: Ch1’s combo connector is wired in parallel with CH1’s terminal block connector). This is useful for daisy-chaining the input signal to other equipment. If you are using the “combo” connector for input, the terminal- block connector can be used for daisy-chaining. If using the terminal-block for input, the “combos” can be used for daisy-chaining. Remember to disconnect unused inputs; any input signal on either input connector will be amplified and output.
If the Mode Switch is set to PARALLEL, all input connectors (CH1 and CH2) are connected in parallel. An input signal applied to any of the four input connectors will drive the amplifier. Any of the unused inputs may be used to daisy-chain the input signal to other equipment. Make sure only one input signal is applied to the amplifier.
The inputs are electronically balanced. To main- tain the benefits of balanced connections, make all connections using balanced, high-quality cable and connectors. If balanced inputs are not available, use an unbalanced-to-balanced con- verter, such as a “DI” box or proper audio trans- former. If the input cables are short and the venue location free of electrical noise, unbalanced input connections may be acceptable. This is not the preferred method, but sometimes necessary. No damage will be done using unbalanced connec- tions, just a reduction in audio quality and performance.
Unbalanced connections are prone to noise and interference pickup as well as ground-loop induced hum. If your system has noise or hum, disconnect all amplifier inputs to verify the source of the noise. If the noise disappears, the noise source is not the amplifier. Check cabling and other equipment connections.
Use balanced connections and high-quality cable and connectors for best results.
Terminal-block jack accepts 3-pin terminal- block plugs.
Combo input jack accepts both
XLR and TRS (1/4-inch) plugs.
