Introduction X2 Reference Manual 9 C HAPTER 1 I NTRODUCTION About the X2 The X2 is an extremely flexible, 24-channel, 8-group output, in-line monitor professional mixing console. The monitor path of each channel has its own 45mm linear fader, automated mute, and access to EQ and Aux sends, so you can mix or monitor one input while the main path mix[...]

Introduction 10 X2 Reference Manual in the console (each channel, monitor, effect return, aux send, and group output). It features its own ADAT Synchronization Interface jack, plus MIDI in/out jacks, so that its built-in 10,000-event sequencer can be synchronized directly to the ADAT system or to a MIDI system. The mutes may be externally controlle[...]

Guided Tour X2 Reference Manual 13 C HAPTER 2: G UIDED T OUR Recorder/Mix Systems The X2 is designed to be extremely flexible, as evidenced by the channel module design. This is where signals are mixed, EQ’d and routed to the Aux sends, Groups and Left and Right Master outs. Each channel provides a Tape In connector, where signals return from the[...]

Guided Tour 14 X2 Reference Manual input appears at the monitor controls. This is the position normally used for mixdown (with the main channel assigned to L-R) or for bouncing tracks (with the main channel assigned to the appropriate Group or Groups). To avoid low-end rumble and noise, turn on the HPF (high-pass filter), which removes frequencies [...]

Guided Tour X2 Reference Manual 15 Aux Send/Return Systems In the center of each channel module is the Aux Sends section, which allows the signal to be routed to outboard signal processing equipment or to feed a headphone amplifier. The first two sends (Aux 1-2) are Pre-Fader, meaning that the signal level is independent of the channel’s fader. T[...]

Connecting the X2 X2 Reference Manual 31 Interfacing to an Unbalanced -10 dBV Multitrack Recorder Interfacing the X2 with a typical multitrack recorder using semiprofessional unbalanced phono or 1/4" phone jacks is a simple process. Alternatively, if you are using one or more ADATs, it is recommended to interface the balanced inputs and output[...]

Connecting the X2 32 X2 Reference Manual Interfacing to a Professional +4 dBu Multitrack Recorder Professional recorders typically feature 3-pin XLR connectors on their inputs and outputs. The nominal signal level of these units is +4 dBu (1.23 volts). Depending on the model of recorder, these inputs and outputs may be balanced, servo-balanced (whi[...]

Connecting the X2 X2 Reference Manual 33 Interfacing to a Multitrack Recorder via a Patchbay It is also possible to access the multitrack tape recorder by the use of a patchbay, which is several rows of jacks that are permanently connected to both the inputs and the outputs of the X2, the multitrack tape machine, and all of the outboard equipment.

To connect the Aux Sends and Stereo Aux Returns to outboard effects: 1 Connect the Aux Sends (AUX 3, AUX 4, AUX 5, AUX 6, AUX 7, AUX 8) to the input or inputs of[...]

Connecting the X2 36 X2 Reference Manual Interfacing the Inserts Insert s are used to connect signal processing devices directly into the signal path of a Channel. Normally, the device connected would be one that shapes the dynamics or tone of a signal (such as a compressor, gate, or EQ), rather than an effects device (such as a reverb). It is also[...]

Applications X2 Reference Manual 37 C HAPTER 4: A PPLICATIONS Recording Setting Levels In order to ensure the cleanest signal with the least amount of background noise (hiss or hum), it is extremely important that proper level setting s be maintained not only within the X2 itself, but throughout the entire audio system. Therefore, it’s best to ob[...]

Applications 38 X2 Reference Manual If several “hot” (loud) Channels are assigned to a Group, it is possible that the Group will overload. Since the internal electronics of the X2 have 18 dB above 0 VU of headroom, it is only possible to clip the Group if: • the Group meter is hitting the top of its range with the GROUP MASTER FADER set to no[...]

Applications X2 Reference Manual 39 Recording Multiple Sources to One Track When more than one Channel is to be recorded onto the same track of a multitrack tape machine, it is necessary to assign all desired Channels to a Group. When the DIR switch of a channel is up, the TAPE OUT jacks receive the signal from a corresponding Group. For example, u[...]

Applications 40 X2 Reference Manual Recording Multiple Sources to Two Tracks (Stereo) Recording multiple sources onto two tape tracks can either be done as two separate Groups or as a stereo mix using two Groups. The former requires that you pan hard left all Channels going to the odd-number Group, and pan hard right all Channels going to the even-[...]

Applications X2 Reference Manual 41 Recording Tips For the cleanest possible recording, the Group FADERS (or Channel FADERS if the TAPE SENDS are being used) should be adjusted so that the level going to tape averages 0 VU on the meters of a typical analog multitrack tape machine (or -15 dB on a digital multitrack machine, such as the Alesis ADAT).[...]

Applications 42 X2 Reference Manual Overdubbing Monitoring the Multitrack on the Monitor Faders Once you have recorded onto the multitrack tape machine, you will want to listen back to those tracks, especially if you are overdubbing new tracks with musicians who need to hear the material already on tape (see next section, Getting the Mix to Headpho[...]

Applications 44 X2 Reference Manual Getting the Mix to the Headphones Once you have the tape tracks returning to the mixer, it is simple to create a cue mix for the musicians to listen to over headphones while overdubbing . The cue mix is created using Aux Sends 1 and 2 on the X2, because the signals from these sends are derived Pre-Fader (before t[...]

Applications X2 Reference Manual 45 Adding Effects Effects such as reverb, chorus and delay are typically wired in a loop from an Auxiliary Send to a Stereo Aux Return (see Chapter 3, “Interfacing Aux Sends and Returns to Outboard Effects”). There are two basic stages to getting a low-noise, distortion-free signal flow from an effects device: 1[...]

Applications 46 X2 Reference Manual 4 Raise the input control of the effects device until its meter or clip LED shows peak level, then lower the input control a bit. Consult the manual for the effect device for more information. Some effect devices have level setting switches on the back; these should be set so that a peak level can be reached with[...]

Applications X2 Reference Manual 47 To make sure you’re hearing what’s actually going to tape, make sure the L-R switch is up, and follow the procedure earlier in this section under “Recording Multiple Sources.” If the effect is stereo, it must be recorded onto two tracks. If you’re recording onto one track only, try setting the STEREO SE[...]

Alternatively, you can also use the MIDI sequencer to record mutes from the X2’s console, thereby bypassing the X2’s built-in sequencer. If you plan to use an[...]

Applications 52 X2 Reference Manual Live Performance Creating a Monitor Mix Most sound reinforcement applications work best in mono, since so few members of the audience are seated in the ideal spot to hear the balance of a stereo sound system effectively. Also, a stereo sound system can be much more difficult to mix. To configure the X2 mixer in o[...]
