Headphones Considerations

The Private Q system with its built-in "Class A" amplifier provides
the highest quality amplification. Because of this very clean sound of
the amplifier, the differences between various types of headphones
become more obvious, similar to differences between studio monitor
speakers. We spent a great deal of time experimenting with different
types of headphones together with some users of the system.
Here are some tips:

The Private Q provides very high (52Vpp) output voltage swing and
can be loaded down to as low as 4 ohms. This is sufficient to drive all
types of headphones and also speakers!!
We found that although the choice of headphones is strictly personal
the following applies:

1. Choose headphones for the main type of music you recording, for
their durability and comfort.

2. If you need extremely loud levels of sound (hard rock drummers)
look for headphones with low or medium impedance (50-100 Ohm),
high efficiency (dB/mW) and good ear isolation. For this purpose we
recommend Fostex T 20 (older version is louder) and Sony
headphones, for example MDRV600. Some Sony headphones you
might find to fragile for studio use. MDRV600 are the LOUDEST
headphones we ever heard.

3. If you are concerned more with sound quality (T20 maybe a little
harsh, while Sonys are usually bright- you can compensate this with
Private Q EQ) try some AKGs (not 240 -they sound thin and are not
loud), maybe Senheiser or look for audiophile headphones but
choose carefully keeping in mind 1.)
Don't spend a fortune on headphones, there are good cost effective
headphones out there.

4. We still did not hear all the headphones so maybe you'll find the
best solution. Please let us know!

From our current experience headphones that work best in a rock and
roll studios are T20s.

Operation

I. Gain Structure

1. Private Q is a +4dBm system. Its inputs are designed to accept
levels at "0 VU". If you are sending levels considerable below 0 VU
you will not get the volume the system is capable of producing.
a. When you use Aux sends to combine signals to send to PQ
channels be aware that sending at 0 VU is important. Check the Aux
send VU meters.
b. When you use multitrack returns to send to PQ then you will
probably be sending a good level already as most engineers are
aware of recording signals at around 0 VU.

2. When starting a session with PQ it is important that the
individual Q boxes have their channel and master volumes set at a
"good" level ( at least 12 o'clock ). The tone control should be set flat
and pan pots appropriately to what the channel is used for.
The maximum gain in each channel is +6dB while unity gain (0 dB) is
at 3 o'clock.

II. What Do You Send To Private Q

1. The basic rule of thumb for fold back mixes: send signals that are
off your monitor but pre monitor fader. In other words send signals
that are post multitrack return. If you use Group Outputs (Busses) to
send to the PQ they must be after the multitrack returns. You should
not use the busses that you are recording to tape as these are off the
inputs and there will be no signal there when you play back the tape.

2. The best sources for signals to send to PQ are:
a. Multitrack return patch points (for individual instruments)
b. Aux (cue) sends for combined signals (stereo drum mix, effects
mix, etc.)

c. Often it is a good idea to send the control room mix to
one
of the stereo channels and individual instruments to the other
channels. This way musicians can use the engineer mix
or update it.
