Mixer / Alto / L-12

Classic

L1 Model I

Alto L-12

Summary

Simplest thing that could possibly work.

Use the ¼ inch phone jack (Tip-Sleeve) outputs to

• The PS1 Power Stand (Classic) / Model I Channels 1 or 2 if you want to use the Presets and the R1 Remote Tone and Level Controls
  OR
  
• The PS1 Power Stand (Classic) / Model I Channels 3 or 4 if you prefer to leave Channels 1 or 2 open for other inputs. You will have to control Tone and relative Level (between the Channels) at your input source, as you do not have this control over Channels 3 and 4 in the PS1 Power Stand (Classic) / Model I or the R1 Remote.

You can use the XLR Balanced outputs.

Outputs

Connnection to a Model I or Classic

This mixer has a button to attenuate the output to match microphone level inputs like those found on the L1 Classic and L1 Model I.

or

Connection to a Model II

Connect to the L1 Model II Analog Input

Connection to a Compact

¼ Inch with suitable output

for PS1 Powerstand Channel 1 or 2 inputs

You can use TS (Tip Sleeve) unbalanced cables, or TRS (Tip Ring Sleeve) balanced cables, but since the ¼ inch phone connections at the Bose Classic and Model I Power Stand are unbalanced there is no particular benefit using balanced cables.

¼ Inch Tip-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)

This should work fine.

¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Sleeve (unbalanced)

This should work fine.

¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)

This should also work, but likely no better than a simple ¼ Inch Tip-Sleeve to Tip-Sleeve cable. This is because the ¼ Inch input on the Bose System is Tip-Sleeve (unbalanced) anyway.

Cables you can use

XLR (balanced) to XLR (balanced)

XLR to XLR, male to female

(balanced to balanced) should be fine. This is the same kind of cable you would use to connect a microphone.

If you use the ¼ inch inputs

Use

• The PS1 Power Stand (Classic) / Model I Channels 1 or 2 if you want to use the Presets and the R1 Remote Tone and Level Controls
  OR
  
• The PS1 Power Stand (Classic) / Model I Channels 3 or 4 if you prefer to leave Channels 1 or 2 open for other inputs. You will have to control Tone and relative Level (between the Channels) at your input source, as you do not have this control over Channels 3 and 4 in the PS1 Power Stand (Classic) / Model I or the R1 Remote.
