MIXER

The TM500 is a practical 12-channel stereo
powered mixer with built-in signal processing in a
compact table top design. The mixer can also be
rack-mounted with the supplied rack ears. It’s ideal
for small club venues, lounge acts and other sound
reinforcement applications. A comprehensive
mixer section with extensive routing and metering
capability, the TM500’s stereo power amp produces
250 watts a side into 4 ohms and features a fan­cooled, bipolar design for greater stability and long
life. A built in DSP section provides 16 different
effects including reverbs, delays, gates, f langing and
more with up to 16 variations for a total of 256. 3­band EQ for the mono channels and 2-band EQ for
the stereo channels is complemented by a dual 7­band graphic EQ for more sonic control. A truly
useful audio tool that offers users exceptional ver­satility and performance in one package.

ARCHITECT’S & ENGINEER’S

SPECIFICATION

The mixer amplifier shall incorporate a 250 W per
channel stereo amplifier, a dual 7-band graphic equaliz­er, digital signal processing and a stereo mixer with 8
microphone-line input channels and two stereo line
input channels. Microphone inputs shall be on XLR­type connectors and line inputs shall be on balanced
1/4

″ phone connectors. Each channel shall have a trim

control (microphone channels) or pad switch (stereo
line channels), one external and one internal effects
sends, 3-band equalization (microphone channels) or
2-band equalization (stereo line channels), pan, a
peak-level indicator and a level control.

Two stereo effects returns shall be provided on
1/4

″ phone connectors, and each shall have an inde-

pendent level control. The mixer shall provide 256
variations of digital signal processing.

Phantom power of +48 volts shall be provided for
operation of condenser microphones. The amplifier
shall be fan cooled. Amplifier output shall be provided
on two 1/4

″ phone connector s per side. Indicator s

shall be provided for output-signal level, power and
+48 volts. The unit shall be a stand alone or rack­mount type (rack ears included).

The amplifier shall deliver maximum power equal
to or greater than 250 watts per side into 4 ohms, sig­nal-to-noise equal to or greater than 112 dB, THD less
than 0.02% and frequency response of ±1 dB from 20
Hz to 20 kHz. The mixer shall have residual noise of ­90 dB and THD less than 0.02%. Dimensions shall be

19.35

″ (491 mm) wide, 13.75″ (349 mm) deep and

5.5

″ (139 mm) high. Weight shall be 36 lb. (16.4 kg).

The mixer amplifier shall carry a three-year warranty.

The mixer amplifier shall be a SAMSON TM500.
