Overview
The Ashly TM-360 is a table-top mixer and 60W mono amplier suitable for applications that
require background music with priority paging from a single microphone. There are two line level
inputs and one mic/line input with switchable phantom power. Input 3 is a line input, input 2 is a line
input with priority over input 3, and input 1 is a mic/line input with priority over input 2. Main speaker
outputs include a 60 watt 4W connection as well as 25V and 70V outputs. 230V export versions have
60 watt 4W, 70V, and 100V outputs. A second zone output is available with a 1W 8W output as well as
a balanced 600W output, and an independent 600W PRE output is available as well.
All input and speaker connections use Euroblock connectors, with inputs 2 and 3 also using
summed mono dual RCA jacks. A rear panel DIP switch determines each input’s zone 2 assignment
status, inputs 1 and 2 priority (mute trigger) status, inputs 2 and 3 mute link status, low cut lter, and
phantom power status for input 1. The TM-360 has a power saving standby mode which can be trig-
gered by audio inactivity or by contact closure. Please read this entire manual to fully understand the
features and proper use of this product.

Front Panel Features
1) Input 2 Jack
This is a 3.5mm Tip Ring Sleeve (TRS) jack on the front panel that drives input 2. This jack is
very useful for connecting MP3 players, and overrides all input 2 connections on the back panel.
2) Input Signal LEDs
These LEDs ash when input signal is present.
3) Input Level Controls
These control the level of the three input channels.
4) Bass and Treble Controls
These control the bass and treble of the main amplier output.
5) Master Volume Control
This controls the main amplier output level. There is a separate rear panel level control for
zone 2 output.
6) Power LED
This LED lights blue when the unit is powered on and active, and red when in standby mode.
7) Power Switch
This switch turns the power on or off

Rear Panel Features
1) AC Mains
This is the AC cord for connecting to 120VAC mains, 60Hz, 24W.
2) Main Speaker Outputs
This 5.08mm Euroblock connector is used for the main speaker output wiring. For low imped-
ance speaker loads, minimum 4
Ω,
connect between the COM and 16V/4
Ω
pins. For 25V or 70V
speaker loads (70V and 100V output taps on 230VAC models), the LINK wire must rst be installed
between the 16V/4
Ω
pin and OPT IN pin, then connect the speaker load between COM and 25V or
70V pins.
3) Zone 2 and Preamp Outputs
In addition to the main 60 Watt amplier output, there is a separate ZONE 2 output which is a
switch selectable mix of channels 1, 2, or 3. This output is not effected by the priority ducking/mute
action or by the bass/treble EQ controls.
The ZONE-2 output provides two signals; 1) a low impedance output that is capable of contin-
uously driving 1 Watt into an 8 Ohm loudspeaker, and 2) a 600 Ohms transformer balanced output.
Zone 2 output is controlled by the rear panel Zone 2 level control, as well as the three channel assign
DIP switches.
The PRE OUT connection is used for driving additional external devices with the same signal
that drives the main TM-360 power amplier. The PRE OUT 600
W
output signal is taken before the
master volume control.
4) Zone 2 Level Control
This controls the level of the Zone 2 output signal.

5) Mix Conguration DIP Switches
Switches 1, 2, and 3: Zone 2 Assign
These assign each input to Zone 2 output, post-level control. There is no effect to the main
output mix.
Switches 4-5: VOX Trigger -
The TM-360 has the ability to trigger a mute on channel 2 or 3 from the presence of an audio
signal on channel 1 or 2. This is called Voice Operated Switching, or VOX. Input 2 has priority over
input 3, and input 1 has priority over input 2. Input 1 also has the ability to use a contact closure
trigger such as a mic push-to-talk switch for priority muting of channel 2. Additionally, input 1 can
be set to have priority over both inputs 2 and 3 together (see switch 6).
The TM-360 has audio detecting LEDs on each input. When the VOX TRIG switches are set
to ON for inputs 1 or 2, the same signal level which activates the LED is used as the VOX trigger.
VOX mutes the dependent channel until the trigger signal falls back below the LED threshold. Each
input features a rear panel gain trim that rst optimizes the overall input sensitivity for each input,
but can also serve to ne-tune the sensitivity of the signal detector which creates the VOX trigger
point for each input.
Switch 6: Mute Link 2&3
When this switch is turned on, it sets the channel 1 VOX trigger or Manual Mute contact
closure to mute both channels 2 and 3. If only channel 2 is to be affected, leave it off.
Switch 7: Low-Cut Filter
This switch turns on a 400Hz 6dB/oct low-cut lter affecting the main and PRE outputs but not
the zone 2 outputs. This is useful for providing the proper EQ for paging horns.
Switch 8: CH 1 MIC Phantom Power
This provides +18V phantom power to input 1 for use with condenser and electret microphones.
6) Input 3 Connectors
3.5mm Euroblock connectors and summed stereo RCA jacks are used for input 3. If wiring an
unbalanced input signal into a balanced Euroblock input, be sure to ground the (-) input pin.

Operating Manual - TM-360 Public Address Amplier
7) Input 3 Gain Control
Input 3 gain trim range is adjustable from -10dB to +10dB
8) Input 2 Connectors
3.5mm Euroblock connectors and summed stereo RCA jacks are used for input 2. If wiring an
unbalanced input signal into a balanced Euroblock input, be sure to ground the (-) input pin.
9) Input 2 Gain Control
Input 2 gain trim range is adjustable from -10dB to +10dB. This control is also used to ne
tune the signal threshold that will trigger the muting of input 3.
10) Input 1 Connector
A 3.5mm Euroblock connector is used for input 1, and can be used as a mic level or line level
input. As a balanced line input, it can connect to a telephone paging system instead of a microphone.
If the input signal is unbalanced, be sure to ground the unused (-) input pin.
11) Input 1 Gain Control
Input 1 gain trim range is adjustable from 0dB to +50dB. A typical line level input setting
would be close to 0dB. A typical Microphone input setting would be closer to +50dB. This control
is also used to ne tune the signal threshold that will trigger the muting of input 2 (or inputs 2 and 3
if linked.
12a) Manual Mute Contact Closure
Contact Closure between pins 1 and G will mute input channel 2, or mute channels 2 and 3
together if they are linked using mix conguration switch #6. This is typically used when a micro-
phone plugged into channel 1 has a push-to-talk switch, whereby the pressing of the switch not only
turns on the mic but also mutes the signal on channel 2, or channels 2 and 3 if they are linked. When
the switch is released, the signal on channels 2 and 3 returns.
12b) Master System Standby
The TM-360 has a power saving standby mode which can be triggered by 25 minutes of audio
inactivity, or by contact closure of the Master System Standby connector pins G & 2. When in
standby mode, the front panel power LED will turn red, changing back to blue for normal operating
mode. Standby mode is ended when there is audio signal present again, or when the Master System
Standby circuit is opened. Master system standby has priority over standby due to inactivity.
