Low/no Volume on Start

Function RoseConnect
#9

I have had this happen twice now in the month or so I’ve owned my RS250.

I’ve only had this happen when using Roon, as I use that 99% of the time. I occasionally use RoseTube, but have not used it enough to have the problem occur.

I use the RS250 RCA outputs set at a fixed 2v output level into my integrated amp. If I turn the amp volume WAY up I can hear music very quietly.

Rebooting the RS250 with the power button has always solved the issue, so far.

Hopefully this is a software glitch that can be resolved.

We are very sorry for the inconvenience caused.
We will fix the symptom and apply it in the next update.

Thank you

Hello @Rosehan.
Will the software update also be applied to the RS520 ?
I recently purchased the RS520 to replace a 12 years old Naim Uniti which had a power output of 50 watts per channel into 8 ohms / 90 watts per channel into 4 ohms. My loudspeakers are Quad S4, with a nominal impedance of 6 ohms, sensitivity is 88db ( 2.83V @ 1M ) with recommended amplifier power of 40watts - 200 watts.
The Uniti could drive the speakers to much higher volume levels than the RS520, which I find surprising when comparing the respective power outputs of the two amplifiers.
I listen to Tidal and RoseRadio. Tidal volume, in particular is very low. I have increased the “ volume settings for each source” from -5db to 0db for both Tidal and Rose Radio. This has brought a small increase in volume but still not enough in my opinion.
This is the only real criticism I have of my RS520. It produces great sound and has great functionality as well. If the low volume issue could be fixed it would make me even happier !
I would appreciate your comments. Thank you.

Hello All, same thing happened coming out of standby:

  1. RS250, latest firmware 4.5.05
  2. Please explain the environment in which Rose equipment is used.
    → Please let us know if you are using an external DAC (USB connection or coaxial/optical, etc.) No
    → Please let me know if AMP is used Yes
  3. Please let me know if you use software volume No
  4. Does the volume decrease occur simultaneously and equally for all sources (music, rosetube, radio, etc.)? I only use Tidal
  5. Is the volume not adjustable when the problem occurs? (Fixed at a small volume and unable to adjust the volume) Volume is near its max to hear music, volume control on external preamplifier
    Or is it a case where the volume is adjusted but the maximum volume is reduced?
  6. Do you set and use a fixed value in the preout level setting? Yes, fixed value for preout
#13

Happened this morning on the latest software 4.6.07 (previously 4.5.07) including Firmware upgrade from 3144 to 3147.

  1. Please tell me the model name of Rose device you are using.
    RS150B
  2. Please explain the environment in which Rose equipment is used.
    → Please let us know if you are using an external DAC (USB connection or coaxial/optical, etc.)
    → Please let me know if AMP is used
    RCA outputs to Amp
  3. Please let me know if you use software volume.
    No
  4. Does the volume decrease occur simultaneously and equally for all sources (music, rosetube, radio, etc.)?
    Was streaming from TIDAL, did not check other sources
  5. Is the volume not adjustable when the problem occurs? (Fixed at a small volume and unable to adjust the volume)
    Or is it a case where the volume is adjusted but the maximum volume is reduced?
    Have fixed volume output on RS150B. Increased my Amp volume to maximum and could just hear the track.
  6. Do you set and use a fixed value in the preout level setting?
    Fixed pre-out to 6500mV

Going to shutdown the RS150B and reboot from power off as not done this since software upgrade.

@ROSEHAN Same problem happened again today as per yesterday, have investigated further and expanded the findings below:

Took the RS150B out of standby using the iPhone APP.

  1. Please tell me the model name of Rose device you are using.
    RS150B
  2. Please explain the environment in which Rose equipment is used.
    → Please let us know if you are using an external DAC (USB connection or coaxial/optical, etc.)
    → Please let me know if AMP is used
    RCA outputs to Amp
  3. Please let me know if you use software volume.
    No
  4. Does the volume decrease occur simultaneously and equally for all sources (music, rosetube, radio, etc.)?
    Volume is very low for all sources at the same low level, Music (off internal SSD), TiDAL, RoseTube & Rose Radio. Using the front panel ‘Mute’ button mutes the audio and when ‘un-muted’ returns to low level. Front panel volume + & - has no effect as have fixed pre-out level.
  5. Is the volume not adjustable when the problem occurs? (Fixed at a small volume and unable to adjust the volume)
    Or is it a case where the volume is adjusted but the maximum volume is reduced?
    Have fixed volume output on RS150B. Increased my Amp volume to maximum (+16.5dB) and could just hear the track. The music plays at a very very low level and only just be heard at maximum amp volume.
  6. Do you set and use a fixed value in the pre-out level setting?
    Fixed pre-out to '6500mV (unbalanced 2200mV)'

This is getting very annoying now. Was this bug meant to be fixed in the very latest software release 4.6.07, if not when is it to be fixed please?

Dear users

We apologize for any inconvenience caused.

We applied the 4.6.07 version after resolving the symptom, but it seems that we need to check it again and update it.
We will fix it and apply it as soon as possible.

Thank you

Checked today and brought the RS150B out of standby from the front panel and very low audio output again. I think the signal level from RCA to my amp is slightly lower than the minimum pre-out level that can be set, so lower than minimum ‘100mV (32mV Unbalanced)’ setting.

#18

Happened again this morning so have temporarily set to using RS150B variable Volume output and set level to maximum. (Not using fixed pre-level output.)

#19

@Woorlord

We apologize for any inconvenience caused.

When the current software volume control function is turned on, this phenomenon appears.
Is the software volume control function turned on?
I was told that this issue would be resolved and updated this week.

Thank you

#20

Version 4.7.01 installed this morning and pre-out levels set to previous 6500mV setting.
So hopefully this issue now sorted. @ROSEHAN thanks for the confirmation on fix.

#21

Same here, just purchased a brand new device and need to set pre-out to 2200mV to get even to close to the volume of my recordplayer or CD transport. Seems very unlogical to me.

expected mcuh more from a device that costs over €2600,-!!!

#22

@Affacc

We apologize for any inconvenience caused.

Please answer a few questions.

  1. Does the system version information of your RS250a display 4.7?
    If not, you need to update to the latest version.

  2. If you do not use the Pre out level setting function, does this phenomenon not appear?

I will forward the symptom to our software team. We will fix any problems as soon as problem accur.

Thank you

#23

I am happy to say that I have not had this issue occur for at least one month. Thank you for the follow up.

#24

@ROSEHAN

The device itself states; Version 4.7

This is what is stated on the App
App 4.7.01.1
Device 4.6

I need to set the pre-out to a minimum of 2000mV to get about the same level of volume as out of my cd transporter or record player.

If I do not set the pre-out the system sounds most of the time like a tin can. And there is serious lack of volume

#25

@Affacc

One more question.

Does the symptom appear when you come out of standby mode and play music?
Or does it appear when you power on the RS250a?

Thank you

#26

@rosehan

It occurs randomly it seems.

During playback, when chosing a different source, as well.

#27

@Affacc

I have a question regarding the RS250 preout level setting issue.

  1. When the symptoms appear, does the sound come out quietly? Or is there no sound at all?
    If there is no sound, turn up the volume of the amp to see if there is really no sound.

  2. When adjusting the volume while the symptom is present, does a pop-up message appear indicating that the volume can be adjusted only when the pre-out level setting is released?

Thank you

#28

@rosehan

When the symptoms appear, does the sound come out quietly? Or is there no sound at all?

sound but like from a transistor radio

If there is no sound, turn up the volume of the amp to see if there is really no sound.

See above (and I know how volume knobs work…)

When adjusting the volume while the symptom is present, does a pop-up message appear indicating that the volume can be adjusted only when the pre-out level setting is released?

Yes

FYI
I have done a full factory reset now and it seems to work now. I haven’t tested it via the app yet only via the device. Will see if the bug appears again and keep you informed
