I've put together some notes about the differences between channel 4 on the T4S and the T1.

The T4S channel 4 compares favourably to the T1 channel 4/5 because T4S channel 4 is fully functional like channels 1, 2, and 3.

T1 channel 4/5 has one function that is not available on the T4S or T8S. T1 channel 4/5 can accept two inputs (left and right from a mixer or instrument) and convert it to mono.  You can combine two inputs to mono on the T4S with the Aux inputs (channels 5/6) but there are no physical controls for those channels.

T4S has the Aux inputs (channels 5/6) and there is no equivalent to those channels on the T1.

T4S ToneMatch MixerT1 ToneMatch Audio Engine
Channel 4
  • Combo 1/4" (6.3mm) / XLR input. This single input is mono and can be panned.
  • XLR input
  • Phantom Power
  • Support for bare piezo pickups (pickups without a preamp)
  • Full support for ToneMatch Presets, zEQ, ParaEQ, Effects, Reverb
  • Can be routed to Aux Outputs 1 and/or 2
Channel 4/5
  • A single mono channel with two 1/4" (6.3mm) balanced line-level inputs that are converted to mono.
  • No XLR input
  • No phantom power
  • No support for bare piezo pickups (pickups without a preamp)
  • Full support for ToneMatch Presets, zEQ, ParaEQ, Effects, Reverb
  • Can be routed to Aux Output 1
Aux Inputs Channels 5/6
  • Two 1/4" (6.3mm) balanced line-level inputs
  • Each input can be panned Left or Right
  • Each input is routed directly to the Master Outputs
    • No processing (ToneMatch Presets, zEQ, ParaEQ, Effects, Reverb)
    • Cannot be routed to Aux 1 or 2
  • Each input level control is set using the Prefs | PAN/AUX settings
No equivalent

Happy reading.

Here's a little more.

The T4S is well suited to a duo with two microphones and two guitars or instruments without preamps. You have four full-function channels and if you are running stereo, you can pan the inputs to either side of the stereo image.

The T1 is well suited for a solo artist with one microphone, one guitar, and backing tracks, and have an extra input for something else.  If you are running mono, this works great. If you need stereo, the T1 wasn't engineered to do that.

On the T4S, to have full control over stereo backing tracks, you will need to dedicate two channels (e.g., 3 and 4). You can use the Aux inputs, but you don't have any signal processing available or physical controls (trim, volume control).

Just wish the ease of use over aux inputs had remained the same as the T1 in that the T4S volume control is buried multi levels deep in the menu system not via a standard pot.

T1 channel 4/5 is a single channel with two inputs that are combined to mono before any processing. This saves having to use two channels to mix down a stereo source. This channel is full-featured (with some limitations on the types of sources it will accept). It's not just an Aux input.

T4S channel 4 is a full-function single channel with one combo input. To accept a stereo source, you need two channels (e.g., 3 and 4) or you can use the T4S Aux channels.

The T4S has no equivalent to the T1 channel 4/5.

The T1 has no equivalent to the T4S Aux channels.

The T4S Aux inputs are not full-featured like the channels 1, 2, 3 and 4, so they don't compare favourably with the T1 channel 4/5 if you want EQ, Effects, Reverb, and physical controls.

If you are running stereo, you will have different priorities compared to running mono.  The T4S is a stereo device so it doesn't have a single channel with a mix-down to mono.
