My Tascam 38 VU meters acknowledge signal input when in "INPUT" mode when it wants to. The channels that do register signal on inputs in "INPUT" mode sometimes do not playback in "SYNC" or "REPRODUCE" modes; there appears to be no signal from the channels on which I just recorded OR some channels play back in one mode and not the other OR the VU meters acknowledge a signal present but I can't hear it's output. What seems to be the problem? Thanks guys.

You're kind of light on details of the equipment you're going to use - so the best I can do is provide generic instructions. You'll need two devices - one must be able to perform playback for source media and the other for recording or copying duties. Inspect the jacks provided on the rear of both units. Most provide standard RCA type "Phono" jacks for left and right audio channels. Connect a stereo patch cable (with plugs that match the jacks of the playback and recording devices) between the left and right OUTPUT (or "PLAY") jacks on the source device and the left and right INPUT (or "RECORD") jacks on the recording device. Insert the source tape, cd, album, etc. in the device that will playback the original and insert a high quality blank media into the device that will provide recording capabilities. Begin playing the source. Set options such as tape bias, Dolby Noise Reduction, etc. on both source and recording devices to match media in each. Advance the playback source to a point that contain the loudest sections. Set recoding levels by monitoring the VU meters on the recoding device and vary the input adjustment levels so that only the loudest prortions of the program just begin to briefly "flirt" with the 0Db or red zone of the meter. Signals that cause the meter to indicate into this area and beyond begin to overload the amount of information that can be recorded on the blank media and often result in muddy audio quality during playback, later. You should also record the same section repeatedly with differnt options (bias, noise reduction, etc.) to actually hear the difference to determine which sounds best to you. Once levels are set, queue the playback device and start recording. In the case of tape, allow enough recording time to let the leader section of the tape to pass beyond the recording heads for several seconds or more. Once the desired amount of silence has elapsed, play the source program. Allow it to run to completion using both sides in the case of tape and then playback the entire new recording to make sure it recorded without any issues.
The output of the Dish Network box should be hooked to the input of the VCR. The output of the VCR should be hooked to the input of the TV. The VCR should be on channel 3 to record. Select channel to be recorded on the Dish Network box.
It sounds like you have Dish Network box output hooked to TV input. & VCR output hooked to an aux. input on the TV.
Have you clicked the little "monitor" icon (looks like a speaker) on the armed audio track so that it goes orange? Once on, you should see a signal on the VU meter (assuming the line in has a good signal etc). Once recorded, turn the monitor off again to listen to the track with all the others.
Chances are that pre-amp IC that controls both channels has failed. Follow the wires from the tape head and trace the signal. Better still start with the output of the deck and trace backwards. If you touch the audio circuit with an insulated screwdriver (don't short anything) it should buzz. when you find something that buzzes on one side (coming out) but doesn't buzz on the otherside (signal going in) then you have found what needs to be replaced.
PS don't touch the power section.
It seems that the recording input source is provided as "Line In" whereas you need to select the "Mic In". This is because the "Line In" is a stereo input and expects input for both right and left channels whereas the "Mic In" input is a mono input which is the same as our default condensed mic device is.
By the way, you would be able to see the graphic VU meters while recording, weren't they displayed that the recording is done only for one channel ? Always use VU meters for checking the levels for recording, they are available with almost all recording softwares.
It sounds like either the inputs are not assigned or the tracks are not armed for recording (or both).
Here is a quick explanation of the procedure involved in recording with the DP-02 that I posted for another person who was asking for some basic instruction on how to record. You might be missing a step somewhere along the line as for instance you will still see the meters move even if you don't have the inputs assigned or don't have any tracks armed, but the DP-02 won't record anything until you do both.
To record you need to first assign your input to a track, then arm the track for recording, and then press play + record at the same time.
1. So you would patch your mixer output, mic or instrument into an input on your DP01 (say input A). You can run some audio to set the level with the input level knob (located next to input A on the front panel).
2. Then to assign that input to a track simply press and hold the 'input A' button and then press the 'rec' button of the track you with to record on. The 'rec' button will flash rapidly to indicate that the input is assigned to the track.
(To assign the input to a different track you have to clear the input assignment from the first track and assign the input to a new track. To clear an assignment press the input assign key, A in this case, and the track it's assigned to will flash its 'rec' button. Hold down the input assign key and then press the flashing 'rec' button. The button will stop flashing and the input can then be assigned to another track by following step 2 again).
3. Next, to arm the track for recording simply press the 'rec' button for that track. The 'rec' button with flash slowly.
4. To begin recording press play + record together in the transport section and the 'rec' light for the armed track will stop flashing and light steadily. Press 'stop' to end recording.
This should get you started. The operation of the DP02 is actually pretty intuitive once you've gone through it a couple of times (which is one of the real strengths of the unit). You'll be multitracking like an expert in no time.
The easiest way to record using an external Lexicon effects unit (without an external mixer) is to connect your mic onto one of the 2488's inputs and assign that input to a channel strip (track). You should have the 2488 sends (output) going to the Lexicon's inputs. Then connect the Lexicon outputs back into another set of inputs on your 2488 and assign those inputs to two empty channel strips (tracks).
Then you will have to take that channel that has your mic input assigned to it and press send and set the levels there to send the signal out the sends (to the Lexicon).
Now you have a channel strip assigned to the mic input which contains your dry signal, and you have the two inputs returning from the Lexicon which contains your wet or effected signal.
You then have some options. You can control the amount of effected signal you hear while recording by adjusting the faders of the two wet tracks and you can either record the dry signal or the wet signal (or both) onto separate tracks.
Typically when recording the singer will want to hear an effect (say reverb) on his voice, but the engineer wants to record only the dry track at recording time (because effects can always be added later, but they can't be taken out). To accomplish this you would use the setup above, but only arm the mic input track for recording. In this way the singer hears the reverb, but only the dry vocals get recorded and the engineer can add reverb to that track again later as desired (and mix it back with the dry vocal etc).
On the other hand if you want to record only the effected signal you would simply arm the two channels to which the inputs coming back from your Lexicon are assigned for recording. This will get you a recording of the effected signal only.
Hope this helps you do what you are trying to do.
