Hi. We intend mixing our school band with Yamaha O1v and recording by
using the digital stereo output into a HHB CDR882 recorder. Testing
the set up, we are inputing Cd audio to the O1v. O1v & HHB are
connected via Digital coaxial connections (HHB adjusts internaly/
automatically to o1v wordclock)

Even with master and channel faders of O1v set at an unusably high
level, the input level as monitored on the HHB is minimal. We
increased the digital input level on HHB to +15db and this gave a
modest improvement.
Is this acceptable to increase the input level so much or does it
suggest a problem elsewhere in the chain?
any advice appreciated.
cheers

It's always OK to do what works, as long as it actually works.

I understand that you're connecting the digital output of the 01V to the
digital input of the CDR for recording. The record level meters on the HHB
should match up with the Master meters on the 01V when you're recording,
no matter what the input source is. But if you're mixing so that the master
meters are only going to a conservative half scale reading most of the time
(this is actually a pretty good thing to do). then the CDR's meters will
only
go up to half scale when recording, and same when playing back the
recorded CD. That's normal. If you want to record at a higher level, that's
fine, but the higher you go, the less headroom you have before clipping, so
you may find yourself riding the level controls more than you'd like.

We use a HHB single drive CDR with the digital output of an 02R96.

Even with master and channel faders of O1v set at an unusably high
level, the input level as monitored on the HHB is minimal.

Sounds to me like the output levels of the 01V might be a tad on the low
side. or not.

However, even with our output levels peaking not that far below below
clipping, we end up cranking in about 10 dB gain on our HHB CD recorder.

We increased the digital input level on HHB to +15db and this gave a
modest improvement.

Shouldn't be a problem. Might even be a good idea to leave a few (3-6) dB
headroom on the finished recordings. I rip the CDs we make and edit and
apply gain to bring the levels on the distributed recordings to peaks of -1.

Is this acceptable to increase the input level so much

10-15 dB is "not so much".

or does it suggest a problem elsewhere in the chain?

IME you are probably in the ballpark.

On the 01v Utility button there is a tone generator facility. Switch
this on (press the utility button however many times you need to to
bring up the screen), set the tone output level to -15dBFS at 1KHz, and
adjust the input level on the HHB recorder to be the same. Then whatever
the levels you set on the mixer will be what is fed into the recorder.
If this doesn't happen then you have a problem, which is beyond me to
fix at this distance.

Other contributors have made good points about keeping the mix levels down.

One more thing - run the master output level fader on the 01v at full
all the time.

Full (+10 dB) or zero dB?

I favor the latter.

Many thanks to all for your responses. We will get rig set up again
and test some of the advice. We will let you know how it pans out.
Your help is much appreciated. cheers

IMO, not a good idea. Mixing live sound is about having options, and any
fader that is already at the top can't be pushed any further, need be.

Hi guys,

On most consoles Full IS zero dB, so maybe you mean Full or -10 dB?

Anyway, I do not see any reason not to have the master fader(s) at
full ( = 0 dB).

If the level has to be pushed any further, that's what the channel
faders are for.
If more volume is needed, then the amplifier(s) should be addressed.
The master faders are not volume control.

On a calibrated console, when your channel gain staging is done
correctly, you balance the mix with your channel faders and you aim
for the nominal level (0 dB) on the master, your levels through the
whole console will be hot while perserving the minimal required
headroom (normally +/-22 dB) for the console.

If you argue that keeping the master faders at -10 dB will increase
the headroom on your master buss with an additional 10 dB, you should
keep in mind that you'll be working at -10 dB below nominal, which is
not optimal in terms of signal-to-noise on one side and headroom on
the other.
Furthermore you may find yourself now pushing all your channel faders
to the max, trying to get some decent master level, and doing so,
eating up all the headroom in each channel.
Should you have adjusted the amplifiers for an input level of -10, do
not make the mistake now to push the master faders up now.

For whatever reason you choose to set your master fader at the -10dB
position, you must consistently keep your levels at this less than
optimal level as well, and keep the master faders fixed at that
position at all times.
So, why not work at the intended "0" dB nominal level with the
corresponding "0" master fader position in the first place.

Regards,
Norman.

Are you getting a "good" level on the 01v meters when inputting the Cd
audio?
If not, check the following:
How are you inputting Cd audio to the 01v?
- 1. Through the channel inputs.
In short:
If you are inputting through the channel inputs, you have to adjust
the channel gain to get your highest peaks at 0dB on your meters with
both your cannel and your master faders at the "0" position (your
master fader has always have to be at the "0" position).
Normally you do this gain staging with in the SOLO (pre fader) mode,
but I do not know the 01v.
If done correctly, the level on the recorder should match the level on
the 01v and as dispayed on the meters.

- 2. Through the 2TR inputs.
When inputting through the 2 track inputs, you have to set the 15/16 -
2TR IN switch to 2TR IN so you can get the Cd audio into the 01v's
audio flow.
In this option, however I do not know if you can adjust the gain or
are limited to the 15/16 channel fader for level conrtol.

If you are testing for the recording, I would use the channel inputs
as in option 1 and apply this basic gain staging procedure for each
channel when recording.

Good luck and have fun with the recordings.

Best regards,
Norman.

CORRECTION!?!
I just found something about the 01v and I see that the meters are
digital meters, where I'm used to working with analogue meters.
SO, YOUR meters should peak at -16 dB(FS) and NOT "0" dB as I wrongly
mentioned ( when my analogue meters show "0" dB, it's -16 dBFS on a
digital meter such as yours).
On your meters "0" is digital clip, you should stay far away from it.
Sorry for the confusion.

By the way, if this -16dB the level your meters are showing that you
find too low, then your levels may be o.k. after all.
