9 XENYX X1204USB/1204USB User Manual PHONES/CTRL R(oom) Use this control to set control room output level and head-phones volume respectively. CD/TAPE TO MAIN When the CD/TAPE TO MAIN switch is depressed, the 2-track input is routed to the main mix and thus serves as an additional input for tape machines. You can also connect MIDI instruments or other signal sources here that do not require any further processing. At the same time, this switch disables the main mix to tape output link. POWER The blue POWER LED indicates that the device is switched on. +48 V The red "+48 V" LED lights up when the phantom power supply is switched on. The phantom power supply is necessary for condenser microphones and is activated using the switch on the rear of the device. ◊ Please do not connect microphones to the mixer (or the stagebox/ wallbox) while the phantom power supply is switched on. Connect micro-phones before you switch on the power supply. In addition, the monitor/PA loudspeakers should be muted before you activate the phantom power supply. After switching on, wait approx. one minute to allow for system stabilization. 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 XENYX display the level virtually independent of frequency. A recording level of 0 dB is recommended for all signal types. 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 tape input, Alt 3-4 and main mix are blocked from the control room outputs, the headphone connector and the level meter. MAIN SOLO (1204FX 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 (1204FX only) The PFL LED indicates that the peak meter is set to PFL mode. Fig. 2.12: PHONES connector PHONES You can connect headphones to this ¼" TRS connector. The signal on the PHONES connection is sourced from the control room output. 2.3.7 Alt 3-4 and main mix fader MODE (1204FX 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. Fig. 2.13: Alt 3-4 and main mix fader Use the high-precision quality faders to control the output level of the Alt 3-4 subgroup and main mix.
