DSP Controls

There’s probably no better way to enhance audio than with the judicious use of effects such as reverb and echo. The TM500 has its own built-in Digital Signal Processor (DSP) chip which provides some of the best effects around.

As discussed in the “Using The Aux Sends and Returns” section on page 20 in this manual, each TM500 channel has its own discrete Aux Send 2 knob. This allows effects to be applied only to certain signals and not just to the overall mix (applying effects to the overall mix could make for a muddy sound). As each channel’s Aux Send 2 knob is turned clockwise, signal from that channel is routed increasingly to the internal DSP (if the DSP On/Off switch (see #19 on page 8) is pressed in [“on”]). Note that the TM500’s master Aux Send 2 Level knob (#10 on page 7) sets the overall amount of level being routed to the internal DSP. For best signal-to-noise ratio, you should use the master Aux Send 2 Level knob and the channel Aux Send 2 knobs to drive the DSP as hot as possible, short of overloading it.

To return signal from the internal DSP, use the Aux Return 2 knob in the TM500 main section (see #9 on page 7) to set the amount of “wet,” processed signal you want to have added to the overall mix. (Note: this knob sets the amount of signal returning from the Aux Return 2 jacks instead when the DSP On/Off switch is off). When set to the fully counterclockwise (“∞ ”) position, no signal is returned from the DSP, so you’ll hear only “dry” signal. Turning the Aux Return 2 knob clockwise will cause more and more DSP (“wet”) signal to be added to the overall mix. When set to the fully clockwise (“+10”) position, the wet signal is boosted by 10 dB. Wet signal is returning at unity gain (that is, with no boost or attenuation) when the knob set to the “0” position.

The Rev To Aux 1 Level control (see #16 on page 7) is used to return signal from the internal DSP to onstage monitors or headphones connected to the Aux Send 1 jacks (when operating the TM500 in standard stereo configuration) or to the right speaker outputs (when operating the TM500 in “split mono” configuration— that is, when the Aux 1 / Monitor switch is pressed in [see #20 on page 8]). See the “Using Aux Sends and Returns” section on page 20 in this manual for more information.

The TM500 provides 16 preset effect Banks (selected with the Bank knob), and 16 Parameter variations for each preset (selected with the Parameter knob), making for a grand total of 256 different reverbs, delays, echoes, flanging, and chorusing effects— all available at the touch of a knob. For each Bank, Parameter 1 provides a “standard” setting— that is, a variation that is deemed as being most characteristic of that Bank type. To quickly audition the TM500 effects, simply leave the Parameter knob at “1” and rotate the Bank knob through its 16 different positions. To hear all 256 effects, change the Parameter setting as you call up each different Bank.

The chart in Appendix A (page 56) lists each Bank as well as describing the sonic variation caused by the different Parameter settings
