FULL INSERT The insert jack is a Tip Ring Sleeve (TRS) 1/4" phone jack, where the tip is the send, the ring is the return and the sleeve is ground. When used as an insert point or in full INSERT mode, the channel is opened up to allow an external piece of equipment to be inserted into the channels signal path. The signal coming from the microphone preamplifier will go out through the external equipment before it can continue back through the channel, re-entering before the channel EQ controls. Most external equipment is not set up for the TRS plug directly so an adapter cable is required. Plug the adapter's 1/4" stereo TRS end into the mixer insert all the way. The two mono 1/4" jacks at the opposite end are the send and return cables. If both an INSERT and a DIRECT out is required, put a "Y" adapter on the SEND cable. INSERTS AND DIRECT OUTS DIRECT OUT (HALF INSERT) Plug a 1/4" mono cable "half way" into the Channel Insert Jack. The "half" insert connection creates a send signal without breaking the channels signal path. The insert in this mode is no longer used as an insert but becomes what is called a DIRECT out. MULTI-TRACK RECORDING A multi-track recorder can be connected to the channel INSERT jacks (1/2 plugged for Direct Out). This set up could be used with a live set up to record a live show. Set the GAIN control at the top of each channel so the signal going to your recorder is not too loud or too weak. Too loud of a signal will distort the input of your recorder, and there is no correction for a distorted track. Too weak of a signal will reduce recording quality and increase noise. With this setup, note that the channel EQ will not affect what is being recorded. The EQ for each track will be adjusted at mixdown. MULTI-TRACK RECORDING SETUP MULTI TRACK INPUTS MULTI-TRACK EDITING To re-record or edit a certain track while listening to the tracks you want to keep, you can setup only the channel you want to re-record for "Recording". Have the other channels set up for "Mixdown". On the multi-track recorder, enable "Record" ONLY for the channel you want to edit or the other recorded tracks will likely be erased. MULTI-TRACK MIXDOWN Use this set up for mixing down from a multi track recording to a two track recorder, or to the built-in USB stereo output. Connect the Multi-track recorder's outputs to the LINE inputs of the channels. Each channel's Gain control should be set to minimum and use the channel fader for level. Monitor your mixdown sessions with high quality headphones connected to the Headphone jack, or connect a professional power amplifier (Carvin's DCM power amps) and high quality studio monitors to your main L/R outputs. The internal DSP or the external effects loops can both be used during mixdown. Mixing is a practiced skill. A trained ear will know when to add EQ, effects, compression, gate. Listen to your favorite CD through the same headphones or monitoring system you plan to mix through. Note each instrument's level and position in the stereo mix. Use this as a guide to help mix your project. ALTERNATE RECORDING SETUPS Another way to connect your multi-track recorder is to use an insert adapter or TRS cable on each Channel Insert for each track. Use the "tip" connection for the recorder inputs, and the "ring " connection for the recorder outputs. With this setup, you can record, then mixdown without changing cabling. A much simpler recording setup would be to use a 4-track recorder, and use each of the 4 subgroups as your track outputs. For example, record drums on subgroup 1, vocals on 2, guitars on 3, and bass or keys on group 4. This is much more limited to what you can to with mixdown, but can be great for a live recording at a show when limited time is available for setup or recording. MULTI-TRACK MIXDOWN SETUP MULTI TRACK OUTPUTS USB IN/OUT USB TO COMPUTER STEREO RECORDER The rear USB connector offers an added interface for recording. Connecting a USB cable between a computer and a USB equipped Carvin mixer will allow recording on a computer (with compatible USB drivers and software). The L-R stereo mix, (pre-fader, pre-graphic EQ) is sent via the REC OUT USB LEVEL to the rear USB port. Inversely, you can bring audio in from computer playback via USB. The audio comes into the RETURN 4 bus on the mixer to the RTN4/USB LEVEL control. The USB features up to 48kHz, 16 BIT audio resolution. 13
