Dual TRS 1/4 to TRS Jack - Bad method??

At the moment I'm using this cable running from the outputs of the synth to a trs jack input to the mixer and also the same for another keyboard to record.

However, is this a bad idea?,

If the input to the mixer is a balanced TRS mono input, then yes, bad idea.

You would be putting the stereo output of the synth/keyboard into the two sides of a balanced mono input.

Mono mic/line channels:
• XLR microphone input jack
• 1/4" TRS line-input jack
• Phantom power, globally switched
• Variable input trim (0 to +50 dB)
• Overload (OL) indicator LED
• Monitor Aux Send with Pre/Post switch
• Post-fader FX Aux Send
• 3-band EQ
• 75 Hz low-cut fi lter
• Pan control
• Mute switch (Mute/Alt 3-4 switch on 220FX)
• Solo switch
• Sub 1-2 and L-R assign switches (260 FX only)
• 60 mm fade

So bad then

Not the right way to do it.

Should just use a pair of normal TS instrument cables for each synth/keyboard (or TRS cables if balanced outputs from synth/keyboard), and connect the left and right main/stereo outputs of each synth/keyboard to a pair of mixer channels each, or use them in mono and only connect one output of each synth/keyboard to one mixer channel.

cheers mate

if it's for a keyboard/synth with a headphones jack, you can probably get a stereo signal by running the stereo end of the cable from the HEADPHONES jack of the keyboard and then run the L/R cables into 2 channels on the mixer... not the best route, but at least it'll be a stereo signal.

cheers its what I was currently doing but I was worried about losing fidelity

Ahhh, if using the TRS end of the cable on a stereo headphone output of the synth, and connecting it to a pair of mixer channels, then that is fine.

I thought you were connecting a pair of outputs on the synth, with a single TRS connection at the mixer, into a single mixer channel, which is not good.

Are "TS" cables just unbalanced 1/4 inch?

Yes, just standard guitar/instrument cables.

TS = tip and sleeve connected, unbalanced
TRS = tip, ring, and sleeve connected, balanced, or stereo unbalanced

Thanks. I knew tip ring sleeve, so I just assumed. Always grateful for knowledge. Thanks
