PS1 Connections Channels 1 & 2
Contents
Connecting Other Equipment
Connector Types
This section is an overview of connections you can make from a other equipment (mixer, music storage device, etc.) to the PS1 Power Stand (Classic) / Model I.
Audio equipment inputs and outputs are either balanced (three conductors) or unbalanced (two conductors). Balanced signals have the potential to be more resistant to hum and noise.
In addition different kinds of connectors are used for the input and outputs.
Here are the main types:
- XLR, male (prongs) and female (receptacles for prongs), usually balanced
- ¼ Inch, male (shaft) and female (receptacle for shaft), balanced (tip-ring-sleeve on shaft) or unbalanced (tip-sleeve)
- RCA, male and female, always unbalanced
- ½ inch mini (male and female), balanced (tip-ring-sleeve on shaft) or unbalanced (tip-sleeve)
Cable Types and Connection to the PS1
Note: The PS1 Power Stand (Classic) / Model I Channels 1 and 2 ¼ inch inputs are unbalanced. There are many kinds of cables that will work but no connection that uses the ¼ input will be balanced because the internal connection is unbalanced.
XLR (balanced) to XLR (balanced)
This is the same as a microphone cable but is also used to connect a balanced line output to a balanced line input.
¼ Inch Tip-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)
These cables are prone to noise if you are running long lines (greater than 20 feet). Consider using shorter cable runs, or running a balanced line. You can use a short unbalanced cable to a DI or Direct Box (to convert from unbalanced to balanced) and run an XLR to XLR cable from the Direct Box to the Bose System.
¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Sleeve (unbalanced)
No issues.
¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)
No issues but no better than a simple ¼ Inch Tip-Sleeve to Tip-Sleeve cable because the ¼ Inch input on the Bose System is Tip-Sleeve (unbalanced).
XLR (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)
No issues but because all four ¼ Inch inputs on the PS1 inputs are unbalanced, this cable provides no advantage over an unbalanced cable.
XLR Female to ¼ Inch Tip-Sleeve
No particular benefit to using this kind of cable as compared to the one above.
¼ Inch Tip-Ring-Sleeve (balanced) to XLR Male (balanced)
Specialized instrument cable (probably Guitar)
This is probably a specialty cable that was supplied with the instrument. It is intended for a microphone input on a mixer and will work fine with the Bose System.
XLR Female (balanced) to ¼ Inch Tip-Sleeve (unbalanced)
This is often used as a Microphone adaptor cable. Can be problematic. Sometimes you see these being used for home karaoke machines and are not suitable for professional use. The ¼ Inch input was designed for high impedance line-level inputs and may not provide enough gain for a microphone which is probably low impedance.
¼ Inch Tip-Sleeve (unbalanced) to XLR Male (balanced)
This is probably an Instrument adaptor. May be problematic. You are probably running an impedance mismatch (high impedance from the instrument to low impedance balanced XLR).
Things you can do if the signal is too high for PS1
- check to see if there is a 'pad' built-in on the mixer (most Mackie mixers have this on the panel beside the XLR outs)
- turn down the main outs on the mixer
- use a 20 dB Pad (attenuator) between the mixer and the Bose System.
