LEVEL METER

The high-precision level meter accurately displays the appropriate signal level.

LEVEL SETTING:

When recording to a digital device, the recorder’s peak meter should not exceed

0 dB. This is because, unlike analog recordings, slightly excessive levels can create

unpleasant digital distortion.

When recording to an analog device, the VU meters of the recording machine

should reach approx. +3 dB with low-frequency signals (e.g. kick drum). Due to

their inertia VU meters tend to display too low a signal level at frequencies above

1 kHz. This is why, for example, a Hi-Hat should only be driven as far as -10dB.

Snaredrums should be driven to approx. 0 dB.

◊ The peak meters of your EURORACK display the level virtually

independent of frequency. A recording level of 0 dB is recommended

for all signal types.

MODE (UB1204FX-PRO only)

The MODE switch determines whether the channels’ SOLO switch operates as PFL

(Pre Fader Listen) or as solo (Solo In Place).

PFL

To activate the PFL function, depress the MODE switch. The PFL function should,

as a rule, be used for GAIN setting purposes. The signal is sourced pre-fader and

assigned to the mono PFL bus. In the “PFL” setting, only the left side of the peak

meter operates. Drive the individual channels to the 0 dB mark of the VU meter.

Solo

When the MODE switch is not depressed, the stereo solo bus is active. Solo is

short for “Solo In Place”. This is the customary method for listening to an

individual signal or to a group of signals. As soon as a solo switch is pressed,

all channels in the control room (and headphones) that have not been selected

are muted thereby retaining stereo panning. The solo bus can carry the output

signals of the channel pan controls, the aux sends and the stereo line inputs.

The solo bus is, as a rule, switched post-fader.

◊ The PAN control in the channel strip offers a constant power

characteristic. This means that the signal is always at a constant level,

irrespective of its position in the stereo panorama. If the PAN control

is moved fully left or right from center, the level increases by 4 dB

in that channel. This ensures that, when set in the center, the audio

signal is not louder. For this reason, with the solo function activated

(Solo in Place), audio signals from the channels with PAN controls that

have not been moved fully to the left or right are displayed at a lower

volume than in the PFL function.

As a rule, solo signals are monitored via the control room outputs and

headphones connector and are displayed by the level meters. If a solo switch is

pressed, the signals from the 2-TRACK INPUT, Alt 3-4 and main mix are blocked

from the control room outputs, the headphone connector and the level meter.

MAIN SOLO (UB1204FX-PRO only)

The MAIN SOLO LED lights up as soon as a channel or aux send solo switch is

pressed. The MODE switch also has to be set at “Solo”.

PFL (UB1204FX-PRO only)

The PFL LED indicates that the peak meter is set to PFL mode.

PHONES

You can connect headphones to this ¼" TRS connector. The signal on the PHONES

connection is sourced from the control room output.

MAIN OUTPUTS

The MAIN outputs carry the MAIN MIX signal and are on balanced XLR connectors

with a nominal level of +4 dBu.
