R1 Remote
These are tips for living with the R1 Remote Control Unit
Contents
Packing It
Ken-at-Bose [1] says
Don't put the Remote Control in the outside pocket of the Power Stand gig bag. It'll get hit during transportion.
The gig bag for the upper half of the Cylindrical Radiator(tm) speaker is designed to leave room for the Remote alongside the bayonet; this is a good protected area.
Stiff Controls
If the knobs get stiff, you can pull them out a bit. Chances are they've just gotten jammed down during packing.
Do You Have to Use the R1?
If you power up the System without the Remote Connected, the PowerStand operates as though the Remote is connected with all controls straight-up (12 o'clock) position.
The PS1 power stand continuously senses activity at all preset selectors and what is connected at the input/output jacks. In general, it is not recommended to operate without the remote connected. The PS1 power stand can however function without the R1 remote control. If you power the PS1 power stand on without the R1 remote control connected, it will operate as if the R1 remote control was connected and at a fixed setting of 12 o'clock (center position) on all the control knobs. Alternatively, if the unit is powered on with the R1 remote control first connected and the user then disconnects the R1 remote control, it will retain the last settings of the R1 remote control before you disconnected it. This is helpful in the case where sharing may be necessary.
Even without the R1 Remote control the system can get to full output if the input trims are carefully set.

Stiff Controls
If the knobs get stiff, you can pull them out a bit. Chances are they've just gotten jammed down during packing.
What do the LEDs mean?
There are two LEDs on the R1 remote control, one for Channel 1 and one for Channel 2.
The LEDs indicate that a certain level of signal has been reached at a point after the preamp and after the insert loop and before the conversion of the signal from analog to digital.
The LEDs are independent of the Master Volume Control at the bottom of the R1.
The LEDs turn from off → green when there's more than a little bit of signal in the channel.
The LEDs turn from green → red when the signal reaches a threshold that is about 10 dB below the level that would clip the A/D converter and cause objectionable distortion.
If the LED is only flickering red the signal is in a safe range and there will be no distortion.
If the LED is red most of the time the signal is too high and this is what you do.
- 1) Check the LED on the PS1 power stand for that channel. If it is red most of the time, turn down the Trim Control for that channel on the PS1 until the LED on the PS1 power stand is only flickering red.
- 2) Check the LED on the remote. If it is still red most of the time, turn the Channel Volume Control for that channel down on the R1 remote until LED is only flickering red.
After completing this procedure you may be able to get more overall volume by turning up the Master Volume Control on the R1.
Hint: Many players find it helpful to note their gain settings -- trim on the PS1, channel volume and master volume on the R1 -- and make sure these levels are set properly during setup.
Connections
Two R1 Remotes for One PS1 Powerstand
Can I have more than one R1 Remote connected to a single PS1 Powerstand?
No - Please don't try to connect more than one Remote to a Power Stand (or more than One Power Stand to a Remote) Daisy Chain Remotes?
One R1 Remote for Two PS1 Powerstands
There are two connections on the R1 Remote. Can I connect two PS1 Power Stand (Classic) / Model Is and control them simultaneously?
No. The two connections are just for convenience to allow for more flexible routing of the remote cable.
You can, however, set up one PS1 Power Stand (Classic) / Model I with one R1 Remote, then unplug the R1 Remote from the first PS1 and plug it into the 2nd PS1 to get that one set up.
The first PS1 Power Stand (Classic) / Model I will retain the settings present at the time you unplug it.
Please note: This will not let you dynamically control two Systems during a performance, but you can at least get them all set up properly even if you only have one working R1 Remote.
Vocals on the Left
I always wire up the PowerStand so that the vocals are in Channel 1. This just means that it's always the same, easy to describe, and one less thing to wonder about. (exception below)
Two Players
If you've got two players sharing a System, and hence the Remote, take a moment to wire things up so that the Channel strip that affects someone's sound is closest to them.
Leave 'em Hanging - (not)
Here's an idea for a bracket you can mount on the mic stand. Sure, the velcro is fine but ...

Zipper Sounds, Latency
Hilmar-at-Bose [2]
...there are two design related issues that come into play here. The reason why nearly nobody knows about this is that rarely anyone ever notices it.
1) The Level knob on the R1 Remote has a certain amount of latency. It takes a moment from the time you turn a knob until the setting actually takes effect. The exact time depends on the circumstances, but it's always less than one tenth of a second which is indeed barely (if at all) noticable.
2) The Channel 1 and 2 Level controls produce a very slight "zipper" noise when they change between different volume setting. That noise does not affect the tone controls or the master volume. The technical reasons for that are complicated, but I'm happy to explain it, if someone is interested. Anyway, the "zipper" noise only occurs when you actually operate the control, so it doesn't occur while playing unless you play and adjust at the same time. If you need to do that (e.g. for a fade-out) and the zipper is audible and objectionable, you could maybe use the volume control on your instrument or the master volume on the remote.
Again, most people never notice these issues in the first place and if they do, it's rarely a problem of any sort.
Muting
Channel 1 and 2 Controls on the Remote don't mute the channels.
Quoting Hilmar-at-Bose[3]
The channel volume controls have about 40 dB gain from all-the-way-down to all-the-way-up but don't completely mute the sound.
